Distilling essential oil can be used for aromatherapy, in cuisine, beauty, healing or to set a mood. Here's the methodology to capture the aromatic florals from rose, lavender, sage and other flowers and herb. Science of Alchemy: Simple Distillation Process Herbal Remedies in Medieval Alchemy Secrets of Aqua Vitae in Alchemical Science What is Steam Distillation? Steam distillation is a separation process using steam to extract volatile aromatic compounds from plant material. The process works by passing steam through the plant material, causing the essential oils to evaporate. The steam and oil mixture is then cooled, allowing the essential oil to condense and separate from the water. For citrus the cold-press technique is better citrus oils. The essential oils are in the peel. Resin oils, alternately, are separated with solvents as resin melts when heated. Steam Distillation in Ancient & Medieval Alchemy Oil of Philosophers: Alchemy Health & Beauty 5 Waters of Ancient Alchemy: Aqua Caustic Distillation separates components of a mixture based on differences in their boiling points. In aromatherapy, the most common method is steam distillation, where steam is passed through plant material to vaporize the essential oils. Materials Distillation Apparatus : Distillation kits can be found online or assembled at home using a pot with lid; a heat-proof bowl; a heat source and ice. Fresh Plant Material : Choose your desired type: floral petals, resinous materials or citrus peels. Water : Distilled or purified as desired. Ice : For creating condensation, if required.

Set the heat-resistant bowl inside the pot, making sure it floats above the water. Add Flowers : Fill the water with flower petals. Cover with a lid turned upside down. The lid should cover the pot, with the inverted end over the empty bowl. Fill the lid with ice to speed condensation. Alchemy: Ancient Mordant Recipes for Fabric & Stones Isabella Cortese: Renaissance Writer, Alchemist, Entrepreneur Asphodel: Ancient Dye & Medicine Plants As the water heats to boiling, the vapors containing both water (hydrosol) and essential oils condense on the inverted lid. The liquids run down the lid into the bowl. They can be separated as the oils cool and float on top of the hydrosol Collection : After 30-60 minutes of steam distillation, collect the liquid from the bowl. The oil will typically rise to the top and can be separated. Angel of Violet Light: Magnum Opus Alchemy Alexandria: Jewel of Ancient History Alchemists of Ancient Alexandria With the lab setup the oils should travel through a condensing tube as vapor, condense and drain into a collector vessel such as a measuring beaker or jar. Safety Precautions Always work in a well-ventilated area. Use caution when handling hot equipment to avoid burns. Ensure your workspace is clean to prevent contamination of the essential oil. Beware of unscrupulous online lab equipment vendors The time varies but can take several hours. The plant material can be restocked as necessary during the process.

Perfumes are grouped according to their strengths. Every fragrance has a purpose, from a fresh splash of rose or mint to mysterious woodsy musk. Perfumery opens worlds of enchanting aromas, deep emotions, harmonious scents and vibrant cultural connections. Kohl: Eye Beauty Magic of Ancients DIY Perfume Artisans: Top, Middle & Base Notes Alchemy of Perfumes: Scents, Cologne, Rose Water In ancient civilizations like Mesopotamia, Egypt, and the Indus Valley, aromatic herbs and oils are significant in religious and medical practices. In ancient Egypt, for instance, scents from flowers, spices, and resins are treasured by royalty. Incense is prescribed medicinally. By the Renaissance, the art of perfumery takes bold steps in Europe. In Grasse, France premium fragrances are cultivated. In Italy, enterprising women like Isabella Cortese and Caterina Sforza raise the standards for cosmetics, medicines and scents. Perfume is classified into several categories based on the concentration of fragrance oil. This classification indicates the intensity and longevity of each type. Below are the most popular types: Eau de Cologne, Eau de Toilette, Eau de Parfum, and Perfume (Extrait de Parfum). 12 Steps to the Magnum Opus: Ripley Scroll Oil of Philosophers: Alchemy Health & Beauty Arcanum Joviale: Alchemy of Sudorific Sweat Types of Perfume Understanding the different classifications of perfumes is key to selecting the right fragrance for any occasion. Below are the four main categories, each defining the concentration of fragrance oils and the resulting scent intensity. 1. Eau de Cologne (EDC) Scent Profile: Light and refreshing Concentration: 2-4% fragrance oil Longevity: Lasts about 2-3 hours Eau de Cologne is characterized by its lightness, making it a popular choice for casual daytime wear. With a refreshing burst of citrus and floral notes, EDC is perfect for warm days or when you want to evoke a sense of vitality. The low concentration of fragrance oils allows it to evaporate quickly, which is ideal for those who prefer to reapply scent throughout the day. Science of Alchemy: Alchemical Innovations Steam Distilling Floral, Resin & Citrus Essential Oils Science of Alchemy: Simple Distillation Process 2. Eau de Toilette (EDT) Scent Profile: Soft yet stronger than EDC Concentration: 5-15% fragrance oil Longevity: Lasts about 4-6 hours Eau de Toilette strikes a balance between subtlety and strength.

DIY perfumes are all about crafting a unique signature scent or giving fragrance as a gift, the benefits of aromatherapy and expression of creativity. Top, middle and base notes are integral to any perfume. Alchemy of Perfumes: Scents, Cologne, Rose Water DIY Perfumes & Cosmetics: Ancient Medieval Distillation in Alchemy: Ancient Process & Equipment Top, Middle & Base: Demystifying Perfume Notes With personally crafted perfumes the artisan is in control of the strength, fragrant notes and emotional appeal of the aroma. Perfumes are composed of layers of scents, commonly referred to as notes. Each note contributes to the overall character of the fragrance. Top Notes Top notes are the first impressions of a perfume, or the initial scent when it's applied. These notes are lighter and more volatile, usually lasting 15-30 minutes. Common top notes include citrus, herbs and some fruits. These include: Citrus : Notes like lemon and bergamot offer a vibrant, zesty scent to awaken the senses. Mint : Crisp and invigorating, mint adds a fresh element both delightful and energizing. Green Apple : The sweet, fruity aroma of green apple is a playful and lively start. Eucalyptus: Lively and bright with refreshing zing. Top notes are essential as they attract an initial response. Alchemy of Perfumes: Scents, Cologne, Rose Water Science of Alchemy: Alchemical Innovations Renaissance Purgatives & Ancient Remedies Middle Notes Middle notes make up the core of the fragrance and usually appear once the top notes fade away. They bridge the transition from the fresh opening to the deeper base notes. These add character and body to the fragrance composition. Often floral or fruity, common middle notes include lavender, geranium, rose, and nutmeg. Middle notes are often called the heart of the fragrance. Examples of middle notes include: Lavender : This calming floral note adds a fresh touch and promotes relaxation. Rose : A classic choice that exudes elegance and romance, rose enhances the overall blend. Jasmine : Known for its sweet fragrance, jasmine lends a lush and intoxicating character to the perfume. Sweet Marjoram : A blend of fresh, warm notes with a sweet and spicy tang, with a slightly sharp, herbaceous-woody undertone. Fennel : an intriguing mild licorice scent, similar to but softer than anise. These middle notes play a crucial role in connecting the freshness of the top notes with the richness of the base notes, ensuring a smooth transition in the scent. Lavender (Lavandula) Magic of Nature Antimony (Stibnite, Kohl) Ancient Metal of Science & Beauty 12 Steps to the Magnum Opus: Ripley Scroll Base Notes Base notes are the backbone of the fragrance. They emerge after the top notes have evaporated and typically last the longest (up to several hours or even days). Common base notes include resinous materials, woods, and musks. They provide depth and richness to the perfume, making it more rounded and complex. Base notes give depth and richness even after the lighter notes fade away. They are heavier scents that emerge slowly, contributing to the lasting impression. Common base notes include: Vanilla : Sweet and comforting, it smooths and balances other scents beautifully. Musk : This earthy, sensual note anchors the fragrance, creating a complex scent profile. Sandalwood : Known for its creamy and warm woodsy aroma, sandalwood adds longevity to perfume. Cedarwood : another warm wood scent reminiscent of rustic country living, charming and deep. Amber: Earthy resin from fossilized undersea forests, this beauty is traded from the Bronze Age but it's Pliny the Elder in Rome who identifies it as a resin by the scent when it's burning.

Perfumes are prized in ancient civilizations such as Mesopotamia, Egypt, India and China. The word “perfume” comes from Latin per fumum , meaning “through smoke,” which refers to the practice of burning fragrant materials as in incense. 12 Steps to the Magnum Opus: Ripley Scroll Oil of Philosophers: Alchemy Health & Beauty Arcanum Joviale: Alchemy of Sudorific Sweat The global cosmetics market size is USD 295.95 billion in 2023 with the perfume market alone expected to reach USD 64.41 billion by 2030. Cosmetics continue to dominate youth economy in cultures around the globe. Perfumes are infused into human culture for over 6,000 years, emerging in Mesopotamia. These early fragrances are integral to religious ceremonies. For instance, Egyptians use myrrh and spices like cinnamon and rosemary in embalming, along with natron salt. Renaissance Purgatives & Ancient Remedies Giant Cinnamon Birds of Arabia Acetic Acid: Vinegar 🜊 in Ancient Alchemy Aroma-seeking alchemists blend oils and resins to create subtle layers of fragrance. In the ancient world scents are part of rituals and daily life. Incense from floral to spicy, resins such as myrrh and frankincense are used both for fragrance and attributed spiritual properties. Aromatherapy is considered healthy even in the old days. Medicinal incense recipes are created, the products burnt on braziers to spread smoke and scent. Myrrh has the misfortune to be associated with death for several reasons. One, it's used in church paintings of egg tempera to cover up the smell of egg decay and curing, which can take a few months. Alchemical Salt: Essential Salts of Alchemy Myrrh - Mystique, Death & Divinity Art of Egg Tempera: Paint Like the Old Masters Two, it's popular in the "beaks" of plague doctors as a scent to cover the smell of decay. Three, it's used in Egyptian embalming. Four, it has a musty grave-like scent. Nonetheless myrrh is one of the most expensive resins on the ancient world trade routes. In ancient Greece and Rome, perfumes are status symbols. Wealthy citizens commission custom scents crafted by skilled artisans. This burgeoning market drives innovations in extraction and blending, catering to an increasing desire for unique fragrances. Cosmetics have a similarly long and varied history. Kohl ( stibnite ) is used to line the eyes, to provide protection against the sun’s glare and ward off infections. Kohl: Eye Beauty Magic of Ancients Red Ocher (Ochre) Ancient Pigments Talc (Magnesium Silicate): Beauty, Art & Industry Talc, harvested from mineral deposits, gives a silky texture to the skin. Due to concerns about its proximity to asbestos in nature it's less used today, replaced with cornstarch. Mineral clays such as Earth of Chios, Earth of Sinope or Armenian bole are ascribed health benefits. Eau de Cologne is a type of perfume originating in Cologne, Germany. Created by Johann Maria Farina (Giovanni Maria Farina) in 1709, it becomes a general term for fragrant blends with concentration of 2–5% or higher, based on the mix of essential oils, alcohol and water. 12 Renaissance Medicines & Treatments Red & White Tartar: Wine Salts of Alchemy Ethyl Alcohol: Science of Solvents & Booze Typically based on diluted ethanol (70–90%), cologne includes a blend of citrus oils.

Alchemy these days is often seen only as a mystical practice purveying the clic hé of turning base metals into gold. Alchemy is in fact a significant science for two thousand years. It is the only science. The first alchemists appear in ancient Alexandria, in the early years AD. Alchemy: Science, Philosophy, Magic Science of Alchemy: Hydrochloric Acid Cleopatra the Alchemist of Alexandria Distillation One of the earliest techniques developed by alchemists, done in ancient Alexandria with equipment as the alembic and retort, distillation involves heating a liquid to create vapor and then cooling the vapor back into liquid. The pelican vessel and cohobation vessel are used for multiple distillations. Heating liquids can separate the components of a mixture or solution based on boiling points. This understanding led to the production of beverages like whiskey, essential oils and a lot of chemicals. Equipment Alchemists Need: Essential Tools of the Trade After the conquest of Egypt by Islam, Muslim alchemists extend on the work of the Alexandrian alchemists. Jabir ibn Hayyan advances the process of distillation. There is a question as to whether Jabir is one or more people. He invents various distillation devices. Although credited with invention of the alembic, based on al- ("the" in Arabic) and ambix (ambik- ‘cup, cap of a still’ in Greek) it's debatable. Science of Alchemy: Simple Distillation Process Egyptian Alchemy - Power of Eternity Ancient Greek Alchemy: ios and iosis Women in the Sciences The invention of the alembic is originally attributed to Cleopatra the Alchemist in Greco-Roman Alexandria, a major center of glass making. It may be even earlier, from Mary the Jewess , prolific inventor and darling of the Islamic alchemists. Mary invents the bain-Marie. Women are the cultivators of alchemy. Much of later science downplays the role of women because, according to science, females are too stupid to do science. However this doesn't stop Renaissance women like Isabella Cortese , Caterina Sforza or Sophie Brahe . Women of Alchemy: Anna Maria Zieglerin Alchemists of Ancient Alexandria Roger Bacon: Medieval Science & Alchemy Isabella Cortese brings female literacy up with her "Book of Secrets", written in the language of the people. Her book also produces numerous imitators, many by men pretending to be women. Caterina Sforza documents over 400 alchemical formulas and recipes, from medicines to make-up. Her book Experimenti  is full of notes and observations. She records such cosmetic recipes as lotions, lip colors and hair dyes. Sophie Brahe works in astronomy and alchemy, charting the skies at the observatory of her brother Tycho. Literature: Great Literary Patrons in History The Pseudos: Underground Alchemy Writers Writing in Letters of Gold: Ancient Alchemy Sublimation, Crystallization & Other Processes The process of crystallization involves the creation of solid crystals from a solution, melt, or by direct deposition from a gas phase. Crystallization is achieved by changing the solubility conditions of the solute in the solvent, as opposed to precipitation, which results from a chemical reaction. Alchemy experiments involve processes such as sublimation, creation of a gas directly from a solid, and crystallization . In general, alchemy processes are based on nature. Other early alchemy processes still used today include fermentation , calcination and cohobation .

Al-Razi and others experiment with various chemical reactions. Today, acids and bases are fundamental to understanding chemical reactions, creating materials, and synthesizing compounds used in everything from cleaning products to batteries. New Branches of Metallurgy Alchemy is partly a product of ancient metallurgy, the science of extracting and manipulating metals. In metallurgy, alchemy develops as a way to color metals or expand their bulk, and moves on from there. Ancient alchemists develop techniques for smelting, alloying, and purifying metals. Recipes for blending metals, dyeing metals, multiplying metals, metal plating, apart from mordanting and dyeing stones and creating purple are found in the Leyden Stockholm Papyri c. 250 AD. Gold-Making of Maria: Tetrasomia Four Metals Zosimos: First Golden Age of Alchemy Antimony (Stibnite, Kohl) Ancient Metal of Science & Beauty Use of Indicators and pH Testing Arnaldus de Villa Nova, a Spanish physician and alchemist, uses litmus for the first time around 1300. The blue dye is extracted from lichens from the 16th century on, especially in the Netherlands. Use of such natural indicators is important to the alchemical tradition, which uses acid and alkaline ingredients. Alchemists experiment with various substances to understand their properties and reactions with acids and bases. Today, pH testing is essential in fields ranging from agriculture to medicine, enabling precise monitoring of chemical concentrations and reactions. 10 Wise Plants & Herbs for the Elixir of Life Nicolas Flamel: Creation of an Alchemy Legend How to Make Asem: Essential Alchemy Production of Pharmaceuticals As alchemists explore properties of various plants and minerals, they synthesize compounds for medicinal purposes. Paracelsus, Swiss physician and alchemist, is particularly noted for Spagyria, or the alchemy of plants. He visits secluded mountain villages, blending modern knowledge with ancient wisdom. Paracelsus is also a pioneer in using chemicals in medicine. He is among the first to assert disease comes from outside the body and is not a product of imbalanced humors . Renaissance Purgatives & Ancient Remedies Alchemy and the Art of Gold-Making Sirius the Dog Star: Stellar Mythology He gains a vast following and transforms medical practice, leading to formulation of pharmaceuticals using new approaches to drug development. The principles of extracting and testing compounds in medicine is established by alchemists. “... Many have said of Alchemy, that it is for the making of gold and silver. For me such is not the aim, but to consider only what virtue and power may lie in medicines.” Paracelsus 8. Chemical Symbols and Notation As alchemy travels through the ages, the necessity for a universal language becomes clear. Alchemists create symbols to represent different substances and their reactions. In Alexandria these are naturally based on Egyptian hieroglyphs, and evolve from there. Unfortunately the symbolism of alchemy takes a dire turn after medieval times, when meaning is injected into every twitch of an alchemist's eye. This is one the several reasons alchemy is considered a spiritual practice by later interpreters. Living Metals & Genders in Ancient Alchemy Democritus: Laughing Philosopher Ahead of His Time Powder of Algaroth: Antimony Oxychloride Purgative The development of chemical symbols allow efficient documentation of experiments, making complex reactions easier to understand. This innovation has continued to streamline scientific communication, which remains essential for collaboration across disciplines. The oldest chemical element on the periodic table is phosphorus, discovered 1669 by alchemist Hennig Brand. Experiments and theories make valuable progress through work with chemicals, metals, dyes, acids, elements, compounds and processes.

Caterina Sforza (1463-1509) is a remarkable figure of the Italian Renaissance, leading a colorful and controversial life. Alchemy is more than just a pleasant distraction. She puts fire and vigor into the quest for alchemical advancement, and does it cosmetically. Alchemy: Processes Used by Alchemists Rosicrucianism in the Renaissance Sophie Brahe Writer, Alchemist & Astronomer Praised in Rome for her beauty, Caterina Sforza is not just a pretty face. Overall she has three husbands, eight children, a smorgasbord of lovers and a fighting spirit. Imprisoned, she attempts to escape. Regent of a strong nation she rules with decisiveness and ruthless strategy. Cruel in grief, she murders the children and wives of her husband's assassins. She's accused of trying to kill the Pope with poisoned letters. Maybe she does try, but to this day no one knows for sure. Natural Magic of the Renaissance Women Scientists of the Ancient World Gold-Making of Maria: Tetrasomia Four Metals She documents over 400 alchemical formulas and recipes, from medicines to make-up. Her book Experimenti is full of notes and observations. She records such cosmetic recipes as lotions, lip colors and hair dyes. In medicine, she creates formulations to treat various ailments. These range from common fevers and coughs to more severe conditions such as sciatica and tumors. She experiments with teas, tinctures, plant and animal poisons, inhalants, purging treatments, snuff and oils. Unus Mundus One World: Psychology Spagyria: Botanical Science of Alchemy World of Alchemy: A Little History Throughout her Experimenti she explores the properties of talc. Talc, or talcum, is a naturally occurring white clay mineral, the softest stone on the Mohs hardness scale. She uses talc in cosmetics, medicine and alchemy. According to her experiments, talc is effective in beauty as a cosmetic powder and ingredient, and as a cure for poison. It's also capable of turning gold to silver, a reverse of the normal goal. Chrysopoeia - Turning Lead into Gold Alchemy and the Art of Gold-Making Orpiment - Painter's Golden Poison Coloring metals is the subject of many alchemical texts. Alchemy emerges from metallurgy as metal-dyeing, gemology as dyeing of stones to make them look like gems, ancient medicine in use of organic materials to prolong life. Alchemy also produces paint pigments . Caterina's manuscripts overlap medicine, cosmetology and alchemy. She makes cosmetics such as hair dyes and lotions using alchemical principles and methods for production in her recipes. Many alchemical processes, such as desiccation or hydration, mimic those of nature. Kohl: Eye Beauty Magic of Ancients Spiritual Magic - Numbers Three & Nine Ambrosia: Divine Nectar & Immortal Gods Her cosmetic recipes would use "herbs and plants distilled in alchemical vessels". The distillation process, a foundational part of alchemy, is used throughout her manuscript across all disciplines. Her work with medicine is equated with alchemy, a branch of natural philosophy, although between alchemy and medicine there are no borderlines. Physicians are also alchemists. Caterina writes of "elixir vitae, an elixir capable of conferring perpetual health and youth." Hermeticism & Alchemy in Alexandria Michael Maier: Rosicrucians, Art & Alchemy Islamic Alchemy: Abu Bakr al-Razi She claims this elixir has the ability to raise the dead and cure the incurable. The instructions written in her manuscript, "recall the principal stages of the alchemical process as described in many alchemy texts", referring to use of glass vessels common to most alchemists. Under the same principles Caterina also produces a “marvelous and divine water” to improve memory, treat leprosy, and cure many other aches and illnesses. This panacea is considered an alchemical product due to its extraordinary nature, much like the elixir vitae . Alchemy & Astrology: Cosmic Connections Collective Unconscious: Seeking the Whole Zosimos: First Golden Age of Alchemy Not all her experiments are divine in inspiration. She uses alchemy to find the secrets of turning base metals into money metals due to a burden of debt. It's said she makes metal appear to be gold by changing its weight and color via principles of alchemy. Perhaps she uses a recipe similar to the one below. From the c. 250 AD Leyden Papyrus: "For Giving to Objects of Copper the Appearance of Gold And neither touch nor rubbing against the touchstone will detect them, but they can serve especially for (the manufacturing of) a ring of fine appearance. Here is the preparation for this. Zodiac Alchemy - Metals & Planets Emerald Tablet - Sacred Alchemy Text Science of Alchemy: Simple Distillation Process "Gold and lead are ground to a fine powder like flour, 2 parts of lead for 1 of gold, then having mixed, they are incorporated with gum, and one coats the ring with this mixture; then it is heated. One repeats this several times until the object has taken the color. It is difficult to detect (the difference), because rubbing gives the mark of a gold object, and the heat consumes the lead but not the gold." Caterina Sforza is grandmother to one of the major movers and shakers of the Renaissance, Duke Cosimo de' Medici I. He explores the practice of alchemy influenced by her passion for it.

The Renaissance brings a unique approach to medicine. Based on the Four Humors theory of health the Galenic way, purging the body of excessive humors is essential for good health. The concept of purgatives or purgatories shape medical and folk traditions. Powder of Algaroth: Antimony Oxychloride Purgative Amoebae: Microbial Predators on the Move Malevolent Microfungi: Hazards of Health & Home The Renaissance, an active period in art, science, and philosophy, also promotes significant developments in medical practice and understanding of the human body. One of the most intriguing aspects of Renaissance medicine is the concept of purgation. During this time, purging through various methods such as emetics, laxatives, and sweating medications is considered a vital process to restoring health and balance within the body. It's based on the medicine of Galen (129 - 216 AD) and meets fierce opposition by Paracelsus . Prussic Acid: Secrets of Hydrogen Cyanide Natural Health: Paracelsus & Hermetic Principles Spagyria: Botanical Science of Alchemy Purging for Health In the Renaissance, the understanding of health is largely based on the ancient Greek belief in the Four Humors: blood, phlegm, black bile, and yellow bile. Physicians believe the balance of these humors is crucial for health. Imbalance was thought to lead to illness. As such, purgation is believed essential in emptying the body of harmful excesses and toxins. Physicians and practitioners believe by inducing vomiting, diarrhea, sweating, or urination, they can help restore natural equilibrium of the humors, leading to improved health. If a patient has a fever, a doctor might prescribe a purgative to cleanse the body and bring back health. Purging is recommended for the majority of patients with ailments like fevers or digestive issues. Food poisoning is not unusual and the symptoms can actually mimic the cure. Microfungi: Mysterious Web of Life & Death Alchemy Tria Prima of Paracelsus: Three Primes Finding the Philosophers' Egg Fevers, on the other hand, can be instigated. During outbreaks of the Black Plague it's observed those who develop fevers are more likely to survive. Thus many people are exposed to conditions causing malaria, which is believed to be better than getting the plague. Throughout the Renaissance, various purgatives were employed, often drawn from traditional folk remedies and herbal practices. Some of the notable purgatives included: Emetics Emetics are administered to induce vomiting. Common agents like ipecacuanha, a Brazilian plant, and certain vinegar preparations are used to purge the stomach of noxious substances. This technique is believed to alleviate conditions such as nausea, fever, and psychological disturbances linked to “bad humors.” Invisible World: Prokaryotes & Animalcules Jan Baptist van Helmont: Renaissance Medicine Roman Inquisition: Power, Prayer & Politics Laxatives Laxatives are used to relieve constipation and remove waste from the body. Natural laxatives such as senna (in tea), castor oil, and rhubarb are common. Physicians view regular bowel movements as crucial for overall health. Elimination of waste is thought to improve digestion. Sudorifics, Diaphoretics or Sweating Medications These medications prompted sweating and were believed to expel impurities through the skin. Remedies derived from herbs like yarrow and elderflower are used, with the notion that sweating could effectively eliminate toxins, thus treating fevers and other ailments. Sudorifics and diaphoretics have distinct differences. While both play a role in regulating body temperature through water loss and evaporation, sudorifics specifically trigger noticeable perspiration, unlike diaphoretics which stimulate imperceptible perspiration. Science of Onion Tears: Demystifying Acids Isabella Cortese: Renaissance Writer, Alchemist, Entrepreneur Care and Feeding of Your German Kobold When sudorifics are used, the body detects the sweat being produced. The sweat is released in such abundance it can't evaporate quickly, leaving visible drops on the surface. Sudorific medications affect nerve endings in glands, sweat centers, or sensory nerves, prompting sweat glands to work harder. Diuretics Diuretics encourage renal function and increased urination, facilitating the removal of excess liquids and waste from the body. Plants such as dandelion and nettle were popular choices, utilized to treat conditions like edema and urinary tract infections by promoting fluid balance. Diuretics might also be instrumental in acquiring a urine sample. Uroscopy is highly popular in Islamic and European countries for identifying a disease by the clarity, sediment, color and smell of the urine. Doctors might even taste the urine for excess sweetness. Urine in Medieval Alchemy & Medicine Phosphorus, Uroscopy & Power of Pee Pill of Immortality: Chinese Alchemy Other Forms of Purging Beyond these methods, the Renaissance also recognized bloodletting as a purgative practice. This method involved the withdrawal of blood to reduce the volume of humors. Bleeding with or without leeches is a commonly known treatment practiced by doctors and barber-surgeons. Tears, crying: can be induced with onions due to the mild sulfuric acid content reacting with the surface of the eyes. Sneezing: by 1650 the use of snuff is popular to induce sneezing and clear the sinuses Phlegm-producing: honey, peppermint, steam, ivy leaf and type are some of the natural expectorants used. Spitting up or coughing up phlegm is considered a key to health in the Renaissance. It makes sense as the phlegmatic humor is possibly causing the illness, with an overproduction of fluids. 10 Ancient Spices of Trade, Health & Beauty Earth of Chios: Ancient Alchemy, Cosmetics, & Medicine Nitric Acid: Aqua Fortis the Acid Queen Do Purgatives Work for Health? While some modern medicine acknowledges the potential utility of certain purgative substances in treating specific conditions, many Renaissance practices lack scientific backing. The effectiveness is often anecdotal and rooted in beliefs of the time. Risks of dehydration or imbalances are largely overlooked. Nonetheless, the Renaissance laid the groundwork for further exploration into human health, leading to more rigorous standards of evidence in later centuries. Purgatives were extensively popular from the early 15th to the late 17th centuries. As scientific understanding evolves toward the Age of Enlightenment, the practice of indiscriminate purging starts to wane. Babylonian Astrology: Destiny in the Stars Glass & Arts of Ancient Glass Making 10 Wise Plants & Herbs for the Elixir of Life In the Renaissance, diseases such as plague, dysentery, and fevers are rampant. Conditions involving digestive troubles, constipation and bloating are also common. Purgatives are used not only as treatments for these diseases but as preventative measures for general health and to avoid “miasmas,” the foul air considered to cause illness. In the Imperial period the Romans believe miasmas from swamps cause malaria , and the danger of living near swamps is well known. Other diseases include syphilis , measles and smallpox. Syphilis then is much worse than now, as people break out in such lesions it seems their skin is sloughing off. Difficult living conditions and lack of sanitation bring a need for quick remedies to health problems. Seven Deadly Diseases of the Renaissance Scientific Revolution Europe 1543-1687 Sodium Silicate: Alchemy of Water Glass Facts About Renaissance Purgatives or Purgatories Cultural Roots : Many purgative practices were derived from ancient Greek and Roman medical texts and folklore. Philosophical Foundations : The concept of balance is heavily influenced by the philosophy of Aristotle, emphasizing health as a state of equilibrium. Herbal Knowledge : Renaissance practitioners have a fairly profound understanding of local herbs and plants, often using them in combination for enhanced effects. Social Perception : Health rituals involve purging are sometimes seen as demonstrating a person's wealth and status, with elaborate recipes, exotic ingredients and mysterious bottles indicating affluence. Literacy and Medicine : As medical texts became more accessible due to the printing press, individuals began to self-identify their ailments, leading to increased use of purgatives. Legacy : While the indiscriminate use of purgatives has faded, some herbal remedies and principles of detoxification remain popular in alternative medicine today.

Microfungi are invisible organisms until they flourish and form colonies. Among these are malevolent microbes dangerous to health, crops, trees and buildings. They dwell in hidden places and cause sickness, blight and toxicity in the environment, humans and homes. Microfungi: Mysterious Web of Life & Death Radioactive Gas: Radon (Rn) Noble & Deadly Prussic Acid: Secrets of Hydrogen Cyanide Dark Side of Microfungi: When Fungi Turn Rotten Overall, microfungi are fascinating organisms essential to various ecosystems, performing various jobs from decomposition to nutrient cycling. Several microfungi can cause major problems to human health, agriculture and infrastructure. Here are only a few of these invisible invaders. They cause athlete's foot, crop rot, Dutch elm disease, rice blast, and the infamous toxic black mold. Before the popular understanding of functions of the invisible world, ill effects are blamed on superstitious causes like evil elves. Invisible World: Prokaryotes & Animalcules Jan Baptist van Helmont: Renaissance Medicine Great Advances in Chemistry 1600-1800 Athlete's Foot: Sneaky Attack of Trichophyton Athlete's foot, or tinea pedis , is primarily caused by species of the microfungal genus Trichophyton . These fungi thrive on keratin, a protein found abundantly in skin, hair, and nails. They're usually picked up in communal showers and locker rooms. Infection typically occurs when Trichophyton enters through tiny cracks in the skin, leading to symptoms such as itching, burning, and redness, often accompanied by peeling skin. If left untreated, the infection can spread to other parts of the body and even transmit to others. Proper hygiene and antifungal treatments are essential for controlling this pesky microfungal invader. About 15% of the population will get athlete's foot. When Trichophyton  penetrates the skin, it can cause symptoms such as itching, burning, and blisters and cracking skin. Fermentation: Yeast & the Active Microworld The Microscope: Antonie van Leeuwenhoek Scientific Revolution Europe 1543-1687 Prevention and Treatment Preventing athlete's foot centers on good foot hygiene. Here are key strategies: Keep feet dry : Regularly changing socks and footwear helps reduce moisture. Aim to wear moisture-wicking socks, especially during physical activities. Polyester can cause sweating. Wear breathable footwear : Shoes made from breathable materials can help prevent sweating. Look for designs with ventilation to allow airflow. Use antifungal powders : Applying these products can absorb moisture and inhibit fungal growth effectively. Use as a preventative before fungal infection begins. Numerous over-the-counter antifungal treatments exist, from creams to oral medications. Most cases clear up quickly. Sodium Silicate: Alchemy of Water Glass Secret Lives of Sulfuric Acid-Eating Bacteria Biofilm: Metropolitan Microbes of People & Planet Botrytis cinerea : The Double-Edged Sword of Mold Botrytis cinerea  is a mold known for damaging crops like grapes and strawberries. This microfungus displays a striking dichotomy: it is infamous for causing substantial agricultural losses due to rot, but it also plays a crucial role in creating some premium wines. The Noble Rot Phenomenon Under specific conditions, typically consistent humidity followed by sunny weather, Botrytis cinerea  can induce "noble rot." This process is vital for producing sweet dessert wines, such as Sauternes from Bordeaux. The mold enhances fruit flavor and releases sugars by dehydrating the grapes. The infection leads to the concentration of sugars, creating an intensely flavored and prized sweet wine. While noble rot is a boon, the gray mold can devastate vines if left uncontrolled, resulting in losses over 30% of a vineyard's yield. Botrytis cinerea  infects fruits, vegetables and flowers, rapidly spreading decay. Tartrate Crystals: Secrets of Tartaric Acid Red & White Tartar: Wine Salts of Alchemy Famous Women of Renaissance Alchemy Effective Management Strategies Farmers need to balance harnessing and controlling Botrytis cinerea . Effective strategies include: Monitor humidity and temperature : Ventilation and climate control in vineyards significantly reduce mold growth. Selective harvesting : Picking grapes affected by noble rot while discarding rotten ones prevents spoilage and maximizes quality. Optimal vine spacing : Planting grapevines farther apart improves airflow, helping to manage moisture levels. Dutch Elm Disease: The Silent Killer of Trees Another harmful microfungus is of the genus Ophiostoma , the invisible pathogen behind Dutch elm disease. This devastating disease spreads through the elm tree population, often resulting in significant losses in urban forestry and natural woodlands. Arsenic Trioxide: Paris Green Paint Pigment & Pesticide 4 Infused Wines of Ancient Medicine Mother of Vinegar & Microbial Life in a Bottle The fungi enter the trees via bark beetles, blocking the vascular system and preventing the tree from effectively transporting water and nutrients. As a result, infected trees begin to wilt. The Ophiostoma  fungi cause yellowing leaves, dark streaks in wood and ultimately tree death. The impact of Dutch elm disease has dramatically changed the landscape of many regions, leading to the decline of these majestic trees and the loss of their ecological and aesthetic contributions. Losses in some areas are up to 90%. Control Measures and Solutions To combat this invasive threat, a combination of approaches is necessary: Sanitation : Removing and destroying infected trees helps stop the spread of the fungus. Pest management : Targeting and managing the bark beetles responsible for spreading the disease is crucial. Resistant varieties : Planting elm tree hybrids resistant to the disease can provide long-term solutions in Urbania. Reduction in Chemistry: Gaining Electrons Valerian: Natural Health & Essential Oils Glauber: Preparation of a Golden Spirit of Wine Rice Blast: A Threat to Global Food Security Magnaporthe grisea , a phytopathogenic Ascomycete fungus, is infamous for causing rice blast, a disease affecting cereal crops worldwide including rice, wheat, and millet. With its ability to adapt and overcome resistance in host plants, this fungus poses serious problems. The manifestation of rice blast appears as irregular brown lesions on leaves, which can lead to significant yield reductions. In regions where rice is a staple food, outbreaks can cause famine leading to disease. Rice blast can reduce yields by 30% to 50%. Magnaporthe grisea  infects rice through its leaves. It creates lesions hindering photosynthesis to stunt plant growth. This fungus has a remarkable reproductive capacity. It can quickly spread through entire fields if not controlled. Ancient Grains: Wheat, Barley, Millet, Rice Poison Pigments of Painters: Renaissance Oxidation: Metabolism & Essential Molecular Action Certain strategies help manage rice blast: Crop rotation : Alternating rice cultivation with different crops disrupts the fungus's lifecycle, reducing its prevalence. Resistant varieties : Developing and planting rice varieties that are resistant to the blast is pivotal in preventing serious outbreaks. Timely sowing and planting : Sowing rice at the optimal time can help plants avoid infection during peak vulnerability periods. Stachybotrys chartarum : Toxic Home Intruder Stachybotrys chartarum , commonly known as black mold, is notorious for its toxic effects and association with sick building syndrome. This toxic fungus thrives in damp conditions, often on materials rich in cellulose, such as drywall or wood. Rotten Egg Sulfur Smell: Microbial Processes White Lead Toxic Beauty, Art, Ancient Production Acetic Acid Bacteria for Vinegar Artisans: Acetobacter Exposure to Stachybotrys chartarum can cause abundant health issues, including respiratory problems, allergies and neurological symptoms. According to studies, children exposed to this type of mold have a 50% higher risk of developing respiratory illness. Environmental conditions allowing mold growth include poorly ventilated or water-damaged buildings. Moisture control is critical. Symptoms linked to black mold exposure include coughing, sneezing, and fatigue. Microbial Alchemy: Fermentation, Digestion, Putrefaction The Unseen World: Protozoans in Nature Seven Deadly Diseases of the Renaissance Mold in Buildings To tackle Stachybotrys chartarum , here are essential steps: Identify and repair water damage : Locate and fix leaks or moisture problems to deter mold growth.

Microfungi, including molds, mildews, and rusts create a vast hidden universe. These unseen eukaryotic organisms are essential to ecosystems by breaking down matter and enriching the earth. They're in soil, water, hands and hair. Landing on food they can create a magic show. Great Advances in Chemistry 1600-1800 Secret Lives of Sulfuric Acid-Eating Bacteria The Microscope: Antonie van Leeuwenhoek Eukaryotic Organisms: Molds, Mildews, Rusts Eukaryotic organisms including microfungi are characterized by having complex cells with a nucleus and organelles. Microfungi are also called micromycetes. Within the kingdom of fungi, microfungi are specifically defined by their microscopic spore-producing structures. Molds, mildews, and rusts are all categories of microfungi: Molds primarily reproduce through spores and are often found growing on damp surfaces or decomposing organic matter. Mildews are a type of mold that typically grows on leaves and stems, particularly in warm, humid climates, and can affect plant health. Rusts are obligate parasites that infect plants, leading to crop diseases and significant agricultural impact. Radioactive Gas: Radon (Rn) Noble & Deadly Invisible World: Prokaryotes & Animalcules Jan Baptist van Helmont: Renaissance Medicine Unlike prokaryotes , such as bacteria, eukaryotes have cellular structures and are typically larger and more intricate. Molds show up as fuzzy patches in various colors on foods or damp surfaces. For instance, Aspergillus niger , a common mold, can be found on fruit and bread. Mildews, often gray or white, thrive in humid areas like bathrooms or basements. These are the same places radon gas can accumulate. Rusts are notorious for damaging crops. For example, the wheat rust fungus ( Puccinia triticina ) can reduce yields by up to 70% in severe cases. Other rust fungi include Puccinia graminis , stem or black rust; or P. striiformis causing "stripe, yellow, or strip rust". Meet the Microbes - History of Microbiology Prussic Acid: Secrets of Hydrogen Cyanide Elixir Vitae: Giambattista della Porta Besides the molds, mildews, and rusts, other notable groups of microfungi include: Yeasts: these unicellular fungi reproduce mainly by budding. Some species are used in baking and brewing. Slime molds: These aren't true fungi but share some characteristics. They often exist as amoeba-like cells before forming a fruiting body. Lichen-Forming Fungi: Some microfungi form symbiotic relationships with algae or cyanobacteria, creating a unique organism capable of thriving in extreme conditions. Microfungi is divided into specific groups: Ascomycetes : This largest group produces spores in sac-like structures called asci . Examples include yeast, which is vital for baking and brewing, and truffles, a delicacy worth up to $3,000 per kilogram. Basidiomycetes : Known for their club-shaped reproductive structures, these fungi include mushrooms and rusts. Some species, like the honey mushroom, can cover vast areas underground and may be responsible for up to 80% of forest decomposition. Zygomycetes : This group forms resistant spores known as zygospores. Common examples include the molds found on bread and fruit. Deuteromycetes : Referred to as "imperfect fungi," they primarily reproduce asexually. Many relevant molds, such as Penicillium , used to make antibiotics, are part of this group. Microfungi are found nearly everywhere. They're on soil, rotting organic matter, plant surfaces and in the air. They thrive in moist environments but also survive arid conditions. 80% of all indoor mold cases occur in buildings with water damage. Alchemy: Science, Philosophy, Magic Arsenic Trioxide: Paris Green Paint Pigment & Pesticide Eirenaeus Philalethes: Alchemy & Death in Renaissance London Their ability to adapt to various habitats is crucial to their survival. Microfungi can inhabit environments where life is impossible for many other species. Scientists estimate microfungi occupy over 1,000 different ecosystems, from ocean depths to mountain tops. Microfungi have important functions in ecosystems, including: Decomposition: They break down dead organic matter, returning nutrients to the soil and contributing to the nutrient cycle. Soil Formation: By decomposing dead plants and animals, microfungi enrich the soil, enhancing its fertility. Plant Health: Some microfungi form beneficial relationships with plants (mycorrhizae), assisting in nutrient uptake. Pathogenic Roles: While many microfungi are beneficial, some can be harmful, affecting plant health and yields, thereby influencing ecosystems and agriculture. Microfungi are vital decomposers, breaking down organic materials and recycling nutrients. Without them dead bodies from grasses to humans would pile up. Decomposition aids soil health and sustains the balance of ecosystems, allowing nutrients to circulate continuously. Certain microfungi establish mutually beneficial connections with plants, like mycorrhizal fungi. A mycorrhiza represents the symbiotic bond between a fungus and a plant. The fungus forms in the plant's rhizosphere, which encompasses the root system and vicinity. Roman Inquisition: Power, Prayer & Politics Isabella Cortese: Renaissance Writer, Alchemist, Entrepreneur Care and Feeding of Your German Kobold Mycorrhizae are crucial for plant nutrition, soil biology, and soil chemistry, enhancing nutrient uptake and thereby promoting plant growth and resilience against diseases. Approximately 90% of land plants rely on these fungi to optimize nutrient utilization. Microfungi grow and spread through hyphal growth. They extend their hyphae (thread-like structures) from spore sites, creating a network to explore new substrates. This growth allows them to find nutrient sources. In some cases, wind or water carries spores to new locations. As they penetrate surrounding materials, they secrete enzymes to break down organic matter, and absorb nutrients. Microfungi reproduce via spores, which are lightweight and dispersible by wind, water, or animals. Biofilm Communities: Metropolitan Microbes Goethite: The Other Iron-Rich Mineral Reduction in Chemistry: Gaining Electrons A single mold colony can produce thousands of spores in just a few days. When conditions are right, the spores cultivate thriving new fungal colonies. Microfungi digest organic matter such as dead plants, animals, and other organic materials by secreting enzymes that break down complex substances like cellulose into simpler compounds. They then absorb these nutrients to fuel their growth and reproduction. This function places microfungi at a crucial intersection in the food web. By converting dead matter into accessible forms, they nourish other organisms, particularly plants. Their nutrient cycling capabilities are essential for maintaining the health of ecosystems. Alchemy: Circulation & the Pelican Phantasy Heavy Metals Cadmium, Mercury, Lead, Chromium & Arsenic Microbial Alchemy: Fermentation, Digestion, Putrefaction Microfungi can release various gases, particularly carbon dioxide, during the decomposition of organic matter. They exude nutrients and other organic compounds into their surroundings. Metabolic processes can release gases, particularly carbon dioxide, during respiration. Certain fungi also produce volatile organic compounds (VOCs). These help attract insects or repel pests. Additionally, as microfungi decompose organic material, they release nitrogen and phosphorus back into the soil. Nutrient recycling is fundamental for healthy ecosystems. Microfungi are incredibly effective decomposers due to their ability to secrete a wide range of enzymes capable of breaking down tough materials. These include lignin and cellulose of wood. Human Methane: Meet the Microbes of Flatulence Four Humors & Medical Stagnation Paracelsus: Renegade Renaissance Physician Their microscopic size allows them to infiltrate small spaces, accessing nutrients that larger organisms cannot. This efficiency is critical for nutrient cycling within ecosystems. Microfungi are remarkably efficient decomposers due to: Enzymatic Power : They secrete enzymes that efficiently break down complex organic molecules, unlocking nutrients from dead matter and decaying plants. Hyphal Structure : Their extensive hyphal networks vastly increase surface area, enhancing contact with substrates for effective nutrient absorption. Competitive Advantage : Microfungi can thrive in environments where other organisms struggle, allowing them to colonize and decompose various organic materials successfully. Communication Microfungi communicate through chemical signals in their environment. This lets them coordinate growth and reproduction, respond to nutrient availability, and share resources. This phenomenon is known as fungal signaling or quorum sensing. Some fungi use mycorrhizal networks to share nutrients with neighboring plants. Dubbed the "Wood Wide Web," these networks promote communication and resource-sharing among diverse plant species, strengthening their collective resilience. Microbes: Bacteria, Actinomycetes, Protozoa, Fungi & Viruses Seven Deadly Diseases of the Renaissance Isabella Cortese: Renaissance Writer, Alchemist, Entrepreneur Facts About Microfungi Microfungi are essential for composting , breaking down organic waste and creating nutrient-rich soil. Some microfungi are used in biotechnology , especially in the production of enzymes and organic acids. Not all microfungi are harmful , as many have beneficial roles in promoting plant health and soil fertility. Diversity : There are over 1.5 million known species of fungi, many of which are microfungi. Medicinal Properties : Some, like Penicillium , are pivotal in antibiotic production, revolutionizing medicine. Bioremediation : Microfungi can help break down pollutants in contaminated soils, highlighting their environmental significance. Rapid Growth : Under ideal circumstances, some microfungi can double in biomass every few hours. Dependency on Mycorrhizal Fungi : Approximately 90% of terrestrial plants rely on these fungi for optimal nutrient absorption.

Alchemy seeks the magnum opus or great work. This twelve step program comes from the anonymous Ripley Scroll, so called as alchemist George Ripley is mentioned there in a poem. Here are explanations regarding the practical processes as listed in the Ripley Scroll. Radioactive Gas: Radon (Rn) Noble & Deadly Invisible World: Prokaryotes & Animalcules Scientific Revolution Europe 1543-1687 Phases, Stages & Steps: Origins in Alchemy Lists, steps, stages or phases should not be considered guidelines for all. Besides the Ripley Scroll many other sets of phases also exist, as in the Tabula Smaragdina or Emerald Tablet of Hermeticism. Alchemical texts like the Mutus Libe r and Twelve Keys of Basil Valentine highlight a synthesis of mysticism and practical experimentation. In the end this contributes to the decline of alchemy. In c. 100 AD Maria the Jewess uses a four-color process to explain desired changes in a work involving copper. It's a method of alloying and otherwise treating metals based on the popular Greek palette. Alchemy & the Magnum Opus - Black White Yellow Red Alchemy: Science, Philosophy, Magic Alexandria: Jewel of Ancient History This becomes a constant in recycled meaning, as the work of Maria is beloved even to the present day. However somewhere along the line, by the 13th century, people get the idea steps like these are formulae for turning lead into gold. Philosophical talk of the properties and coloring of metals almost two thousand years later turns into an over-mystified, over-codified representation of rules apparently made up by powerless geeks on a dateless Saturday night. Twelve stages of the Magnum Opus appear in numerous manuscripts. So do seven. In spiritual alchemy ancient use of colors black, white, yellow and red burgeons into therapeutic self-indulgence and somewhere along the line yellow is dropped, but no one seems to notice. Women Scientists of the Ancient World Great Advances in Chemistry 1600-1800 The Microscope: Antonie van Leeuwenhoek Twelve Steps to the Magnum Opus from the Ripley Scroll 1. Calcination The process of calcination involves the heating of a substance to remove impurities and break down its structure. The breakdown of materials through heat, or heat decomposition, is considered the initial step in attainment of the Magnus Opus according to the Ripley Scroll. Fundamentally calcination involves heating solids to a high temperature. The purpose is to eliminate volatile substances, oxidize part of the mass, or make them more brittle. Calcination differs from thermal decomposition, the general process of breaking down a compound with heat. Calcination is a specific type of thermal decomposition achieved by heating a substance to high temperatures in the absence of oxygen to produce oxides. Ornithomancy - Prophecy by the Birds Calcination Process: Alchemy at High Heat Alchemical Salt: Essential Salts of Alchemy 2. Solution (or Dissolution) Dissolution is the process where a solute in a gaseous, liquid, or solid phase dissolves in a solvent to form a solution. Solubility is the maximum concentration of a solute that can dissolve in a solvent at a given temperature. A solution refers to a uniform blend of two or more substances in varying proportions. These can be adjusted continuously to the solubility limit. While "solution" is typically associated with liquids, it can also describe mixtures of gases and solids. For instance, air is a solution primarily made of oxygen and nitrogen, along with small quantities of various other gases, while brass is a solution comprising copper and zinc. Baldness: 9 Natural Cures by Physician Dioscorides Acid-Producing Bacteria in Sulfuric Acid Creation Women of the Wild Hunt: Holle, Diana, Frigg 3. Separation Separation can refer to extraction, distillation, sifting or other methods of separating the components of matter. This is commonly used in the alchemy of plants, Spagyria, but is overall one of the most basic and popular of alchemical steps. Separation can involve one or more steps, such as multiple or circulatory distillation, or various types of separation like smelting then acid treatment. It can be carried out with centrifugal force. Separation is also a type of purification. Distillation is the most commonly employed method for purifying liquids. In its basic form, it requires heating the liquid until it reaches its boiling point. The vapor is directed through a water-cooled condenser, causing it to condense back to a liquid state to accumulate in a flask. Elixir of Life: Alchemy & the Emperor Secrets of Renaissance Herbal Recipes Moonwort (Botrychium Lunaria): Folklore, Magic and Medicine 4. Conjunction / Conjugation The word "conjugation" comes from the Latin meaning "to link together". In organic chemistry terms, it is used to describe the situation that occurs when π systems (e.g. double bonds) are "linked together". An "isolated" π (pi) system exists only between a single pair of adjacent atoms. A conjugate acid is created when an acid donates a proton (H+) to a base, essentially turning the base into a compound with an added hydrogen ion for example, ammonium. Conversely, a conjugate base is residue left after an acid has given away a proton in a chemical reaction. Consequently, a conjugate base results from the elimination of a proton from an acid, which can then attract a hydrogen ion in the opposite reaction. Given that certain acids can donate multiple protons, the conjugate base of an acid might exhibit acidic properties. Etch Carnelian Beads Like It's Indus Valley 2500 BCE Catalase: Unseen Enzymes Essential to Life Peracetic Acid: Origin, Reactions, Hazards 5. Putrefaction Also regarded as a process of decay, putrefaction is the breakdown of matter to its essentials, allowing for the emergence of new forms. Decomposition, the fifth stage of death, comes after pallor mortis, livor mortis, algor mortis, and rigor mortis. This phase involves the deterioration of an animal's body after death. Essentially, it entails the breakdown of proteins, the eventual loss of tissue cohesion, and the liquefaction of major organs. The decomposition of organic matter by bacterial or fungal digestion results in the release of gases. These penetrate the body's tissues, leading to the breakdown of tissues and organs. Fermentation & Rot: Comparing Processes Fermentation: Yeast & the Active Microworld Mother of Vinegar & Microbial Life in a Bottle 6. Congelation / Crystallization Crystallization is the process in which solids are created as atoms or molecules are arranged in a highly organized structure called a crystal. Crystals can form through various methods such as precipitation from a solution, freezing, or occasionally deposition directly from a gas. The characteristics of the resulting crystal are largely influenced by factors like temperature, air pressure, cooling rate, and, in the case of liquid crystals, the duration of fluid evaporation. Salt formation is an example of crystallization. The process involves two main stages. The initial stage is nucleation, which involves the emergence of a crystalline phase from a supercooled liquid or a supersaturated solvent. The subsequent stage is crystal growth, where particles increase in size, ultimately leading to the formation of crystal or crystalline structure. Alchemy Process of Congelation: Freezing, Crystallization 4 Infused Wines of Ancient Medicine Elixir Vitae: Giambattista della Porta 7. Cibation Cibation is the act of feeding the crucible with fresh material. A crucible is a container in which metals or other substances may be melted or subjected to very high temperatures. Although crucibles are historically clay, they can be made from any material that withstands temperatures high enough to melt or otherwise alter its contents. Graphite crucibles are recommended by practitioners today. Wine God Liber: Liberty & Liberal Libation White Lead Toxic Beauty, Art, Ancient Production Alchemy: Circulation & the Pelican Phantasy 8. Sublimation Sublimation is the process where a substance transitions directly from a solid to a gas without going through the liquid phase. The verb form of sublimation is "sublime," or alternatively, "sublimate." "Sublimate" also refers to the material produced through sublimation. The critical point at which sublimation happens quickly is known as the critical sublimation point, or simply the sublimation point. Examples of sublimation include dry ice sublimating at room temperature and pressure, as well as solid iodine sublimating upon heating. Hydrogen Peroxide H2O2 Decomposition Alchemy: Circulation & the Pelican Phantasy Secret Lives of Sulfuric Acid-Eating Bacteria 9. Fermentation Fermentation is a type of redox metabolism carried out in the absence of oxygen . During fermentation, organic molecules such as glucose are catabolized and donate electrons to other organic molecules. In the process, adenosine triphosphate ( ATP), an energy source for cells, and organic end products such as lactate are formed. Because oxygen is not required, it is an alternative to aerobic respiration . Over 25 % of bacteria and archaea carry out fermentation. They live in the digestive system , sediments , food , and other environments. Eukaryotes, including humans and other animals, also carry out fermentation. Asphodel: Ancient Dye & Medicine Plants Vinegar Cures of Physician Dioscorides German House Spirits: Beer Donkey (Bieresel) 10. Exaltation Exaltation (from t he Alchemy Website ) is "an operation by which a substance is raised into a purer and more perfect nature." This can be accomplished several ways already mentioned, or the practitioner can think of something new and exciting. Exaltation is also the process of jumping for joy when the patron hands over the cash. 11. Multiplication The Act Against Multiplication comes into effect in 1404 England, forbidding alchemists to make gold out of thin air or anything else. Specifically, the Act addresses the multiplication of gold from a smaller amount of gold. Multiplication is a common term in alchemy and for centuries alchemists have worked on the multiplication of metals. Thus the English laws hit some hard. About forty years later Charles VI, hoping for war funds, begins issuing special licenses to alchemists. Maria teaches multiplication or diplosis as part of the curriculum in the philosophical and alchemical centers of ancient Alexandria. She explains the treatment of various metals to achieve the effect. Turning lead into gold is a later invention. Arsenic Trioxide: Paris Green Paint Pigment & Pesticide Diplosis: Gold Doubling & Multiplication in Alchemy Apis - Sacred Fertility Bull of Egypt 12. Projection Projection in alchemy involves throwing a ferment or tincture onto a substance in order to effect a transformation of the substance. It's done after the magic philosophers' stone, powder, liquid, vapor is made or discovered. It can be achieved any way at all, for once one has found the mystical philosophers' stone, is anything left to know? Several scam artists of the alchemical past use this process and sleight of hand to convince patrons they could turn more material into gold if only they had the money. This is yet another reason for the decline of alchemy. Among those who claim to have achieved this stage are Edward Kelley , a known con artist, and his friend Michael Sendivogius , a Polish alchemist with fingers in diverse pies.

Arsenic trioxide is a toxic compound with a a long and complex history, known at least by the time of the ancient Romans. Here's a look into its production, scientific properties, reactions with other chemicals, and a pigment used by Impressionists called Paris Green. Lactic Acid Bacteria: Nature to Modern Uses Microbial Alchemy: Fermentation, Digestion, Putrefaction Separatory Funnel: Alchemy Lab Equipment Arsenic trioxide (As2O3) is an inorganic compound composed of arsenic and oxygen. It is a white, odorless powder. Highly toxic, it's associated with historical death and disease due to arsenic poisoning. Despite its toxicity, arsenic trioxide has found applications through history. Arsenic trioxide may have early use by the Alexandrian alchemist Agathodaemon , who takes his name from the serpent protector spirit of the city. Some consider the alchemist mythical, though he's noted to be working in the 3rd century AD. He calls the substance "fiery poison". Digestion & Horse Manure: Alchemy Process Alchemist Dippel: the Frankenstein Files Democritus: Laughing Philosopher Ahead of His Time Arsenic trioxide is produced primarily as a byproduct of the smelting of arsenic-rich ores or during the extraction of gold and copper. In smelting, arsenic-containing minerals are oxidized to form the trioxide. It can be made through the process of heating arsenic ores or arsenopyrite. This promotes production of arsenic vapor. Upon cooling, the vapor condenses into finely crystallized arsenic trioxide. It's sold in crystalline, powder or off-white chunks called white arsenic. Science of Alchemy: Simple Distillation Process Mad Honey - What's the Buzz? Night Raven (Nachtkrapp) Germania Arsenic trioxide can be produced through the regular treatment of arsenic compounds, such as oxidizing (burning) arsenic and arsenic-containing minerals in the atmosphere. An example of this is the heating of orpiment, a common arsenic sulfide ore: 2 As2S3 + 9 O2 → 2 As2O3 + 6 SO2 Congelation  in alchemy is the process of crystallization. In later Renaissance alchemy it's considered one the alchemical methods in creation of the philosophers' stone . Talc (Magnesium Silicate): Beauty, Art & Industry Women Brewers: Brewing History of Europe Kermes Insect & Ancient Red Pigments Properties Molecular Weight : Approximately 197.84 g/mol Melting Point : 817 °C (1,503 °F) Solubility : Soluble in water, with solubility increasing with temperature; also soluble in alcohol and organic solvents. Chemical Structure : Generally exists as a white crystalline solid, often referred to as a trioxide due to the presence of three oxygen atoms bound to arsenic. Arsenic trioxide exhibits a high solubility in water, allowing it to easily react with other substances. Its toxicity stems from its ability to interfere with cellular functions, making it a potent compound with both beneficial and harmful effects. 5 Waters of Ancient Alchemy: Aqua Caustic Queen Eleanor & the Calamitous Crusade Kohl: Eye Beauty Magic of Ancients Arsenic trioxide is reactive and can undergo several chemical reactions: With Hydrochloric Acid : It reacts to form arsenic trichloride and water. With Bases : It can form arsenites, which are salts of arsenous acid, when reacted with alkali materials. In Aqueous Solutions : It readily dissolves in water, leading to the formation of arsenious acid (H3AsO3), a potential source of toxicity in biological systems. Paris Green: Components, Uses, and Hazards One of the notable derivatives of arsenic trioxide is Paris Green, a pigment composed primarily of copper(II) arsenite. Historically used in paint due to its vibrant color, Paris Green has also been associated with significant health hazards, primarily due to arsenic levels. Aluminum(III) Oxide: Secrets of Precious Gemstones Metal to Rust: Unseen Organisms in Action Valerian: Natural Health & Essential Oils Despite its aesthetic qualities, the use of Paris Green (and similar arsenic-containing pigments) is now heavily regulated. It was used in agriculture as an insecticide but is less common today owing to the risks posed to human health and the environment. Paris Green is a favored color of French Impressionists such as Seurat and van Gogh. It's often used in underpainting and has many names including Mitis green, Schweinfurt green, Sattler green, emerald, Vienna green, Emperor green or Mountain green. Alchemy: How to Make Emerald from Quartz Verdigris: Creation of Coveted Blue Green Pigment Aqua Regia: The Green Lyon of Alchemy Side Effects / Symptoms Given its toxicity, exposure to arsenic trioxide can lead to serious health complications. Symptoms of arsenic poisoning include: Acute Symptoms : Nausea, vomiting, diarrhea, abdominal pain, and headaches. Chronic Exposure : May lead to skin lesions, peripheral neuropathy, and increased risk of cancer (particularly skin, bladder, and lung cancer). Even minimal exposure to arsenic trioxide can pose health risks, making safety protocols essential during handling or disposal. Major Uses of Arsenic Trioxide 1.

Insecticide Historically, arsenic trioxide was a common ingredient in insecticides and pesticides. While it is still used in certain agricultural practices, its application is decreasing due to safer alternatives becoming available. 3. Modern Medicine In modern medicine, arsenic trioxide is successfully used as a chemotherapy agent, particularly in the treatment of acute promyelocytic leukemia (APL). Its effectiveness lies in its ability to induce apoptosis (programmed cell death) in cancer cells. 4. Traditional Medicine Arsenic compounds may be used in traditional medicine. Non-standardized dosages and toxic effects pose significant risks. 5. Wood Preservation Arsenic trioxide has been used as a preservative for wood, providing resistance against rot and insects. Due to environmental concerns and health risks, its use is being replaced by less hazardous alternatives.

Radon (Rn) is part of the noble gas family. Colorless, odorless, and tasteless, radon presents unique characteristics and effects on human health and the environment. Radon is found in certain housing types. It's especially prevalent in Canada, Australia and Kazakhstan. Prussic Acid: Secrets of Hydrogen Cyanide Invisible World: Prokaryotes & Animalcules Great Advances in Chemistry 1600-1800 Discovery of Radon Radon is discovered in 1899 by Ernest Rutherford at McGill University in Montreal, Canada. He initially identifies it as a byproduct of radium decay, naming it "niton," based on Latin for several terms: "sleek, bright, gleaming, shining, glowing". Radon is the fifth radioactive element discovered. First called emanation , the radioactive gas is identified during experiments with radium, thorium oxide, and actinium by Friedrich Ernst Dorn, Rutherford and Owens, and André-Louis Debierne. In1923 the element is officially named radon, derived from its parent element radium. Over the years, radon has received increased attention due to health implications and unique properties in science. Scientific Revolution Europe 1543-1687 The Microscope: Antonie van Leeuwenhoek Sodium Silicate: Alchemy of Water Glass After the discovery of radon, various researchers confirm its status as a unique and significant element in the noble gas group. Noble gases include helium, neon, argon, krypton, and xenon. Properties of Radon Radon is categorized by its atomic number of 86. Here are some key properties: Physical State : Radon is a colorless, odorless, and tasteless gas at room temperature. Density : It is significantly denser than air, approximately 8.6 times heavier, making it a unique challenge in various environments. This density leads to radon's tendency to accumulate in lower areas like basements. Chemical Inertness : As a noble gas, radon is chemically inert and does not readily react with other elements or compounds. Radioactivity : Radon is highly radioactive, primarily due to its short-lived isotopes, with radon-222 being the most stable and abundant.

Health risks arise from radon's decay products, known as radon progeny or radon daughters, which are also radioactive. Polonium-218, one of the progeny, is highly toxic when inhaled. Radon in Nature Radon is naturally occurring, primarily generated through the radioactive decay of uranium, which is found in soil, rock, and groundwater. Approximately 0.1 to 0.2 picocuries of radon per liter of air are present in the atmosphere. Radon accumulates in enclosed spaces, such as basements and places of poor ventilation. It's produced in nature from decay of uranium and thorium found in rocks and soil, especially in geological formations like granite.

These minerals make up more than 80% of the rock. Other common minerals include mica (muscovite and biotite) and hornblende. Granite rocks contain up to 3% uranium. In homes built on such soil, radon levels can be higher. The gas seeps out of the ground, collecting in lower levels, corners, under stairs and other poorly ventilated spaces. These can have radon levels exceeding the EPA action level.

Besides granite, minerals potentially high in radon include limestone, some shales and dolomite. Water : Groundwater can dissolve radon gas, which can later be released into the air during activities such as showering or washing dishes. Hazards of Radon While radon itself has no immediate effects, its radioactive properties pose significant health risks. Inhalation of radon gas and its decay products can lead to lung cancer. Reduction in Chemistry: Gaining Electrons Oxidation: Metabolism & Essential Molecular Action Xanthan Gum & Plant Blight: Xanthomonas Campestris As a major cause of lung cancer in the United States, radon is responsible for approximately 21,000 deaths each year. Radon can enter homes through cracks in floors, walls, and foundations, as well as through construction joints and sump pumps. Regular testing is critical, particularly in high-risk areas. Homeowners can mitigate radon effects by improving ventilation and sealing entry points to reduce indoor concentrations. Factors Affecting Radon Concentration The concentration of radon in indoor environments can vary based on several factors: Geological Conditions : Areas with higher concentrations of uranium in the soil tend to have elevated radon levels. Building Construction : Homes with poor ventilation or those built on specific geological materials are at higher risk. Seasonal Changes : Radon levels can fluctuate seasonally due to temperature and atmospheric pressure variations, often peaking during the colder months.

Research : Radon is often used in scientific studies related to radioactive decay and environmental assessments. Mineral Exploration : Geologists sometimes measure radon levels for identifying uranium deposits. Radioactive Decay In the process of radioactive decay, an unstable atomic nucleus loses energy by emitting radiation. This decay occurs in several forms such as alpha, beta and gamma radiation. With radon, decay produces alpha particles, dangerous if inhaled, as it transitions to a more stable form. Acid-Producing Bacteria in Sulfuric Acid Creation Etch Carnelian Beads Like It's Indus Valley 2500 BCE Nitric Acid: Aqua Fortis the Acid Queen The decay chain of radon-222 includes several products such as polonium-218 and lead-214, all of which are also radioactive. Once inhaled, these decay products can attach to lung tissue, leading to cellular damage and increased cancer risk over time. Facts about Radon Here are some intriguing facts that highlight the significance of radon: Noble Gas : Radon is the heaviest noble gas, and it is the only one that is radioactive. This distinguishes it from other noble gases, which are stable and harmless. Short Half-life : Radon-222 has a half-life of approximately 3.8 days, which means it decays relatively quickly. Monitoring Systems : Various monitoring systems exist to detect radon levels in homes, providing crucial data for health safety. Homeowners can test for radon with kits from home improvement stores. Global Presence : Radon is present in every country, with varying levels largely dependent on geology. Countries with the highest presence are Canada, Australia and Kazakhstan. Areas rich in uranium and thorium often report elevated radon levels. Radon has a pronounced affinity for lung tissues.  Due to its density, radon can linger in lung tissues longer than lighter gases, increasing inhalation risk. Radon is used in some spa treatments. Long-term residential radon exposure may contribute to development of basal cell carcinoma of the skin.   In dermatology , radiation therapy is primarily used in the treatment of basal cell carcinoma (BCC) and squamous cell carcinoma (SCC), both definitively and as adjunctive therapy.
