Alembic
An alembic (from ar, الإنبيق, al-inbīq, originating from grc, ἄμβιξ, ambix, 'cup, beaker') is an alchemical still consisting of two vessels connected by a tube, used for distillation of liquids. Description The complete distilling apparatus consists of three parts: the "cucurbit" (Arabic: ; Greek: , ), the still pot containing the liquid to be distilled, which is heated by a flame; the "head" or "cap" (, ; Greek , ) which fits over the mouth of the cucurbit to receive the vapors, with an attached downward-sloping "tube" (, ); and the "receiver" (, ; , or , ) container. In the case of another distilling vessel, the retort, the "cap" and the "cucurbit" have been combined to form a single vessel. The anbik is also called the raʾs (head) of the cucurbit. The liquid in the cucurbit is heated or boiled; the vapour rises into the anbik, where it cools by contact with the walls and condenses, running down the spout into the receiver. A modern descendant of the a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Distillation
Distillation, or classical distillation, is the process of separating the components or substances from a liquid mixture by using selective boiling and condensation, usually inside an apparatus known as a still. Dry distillation is the heating of solid materials to produce gaseous products (which may condense into liquids or solids); this may involve chemical changes such as destructive distillation or cracking. Distillation may result in essentially complete separation (resulting in nearly pure components), or it may be a partial separation that increases the concentration of selected components; in either case, the process exploits differences in the relative volatility of the mixture's components. In industrial applications, distillation is a unit operation of practically universal importance, but is a physical separation process, not a chemical reaction. An installation used for distillation, especially of distilled beverages, is a distillery. Distillation include ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cleopatra The Alchemist
Cleopatra the Alchemist (Greek: Κλεοπάτρα; fl. c. 3rd century AD) was a Greek alchemist, author, and philosopher. She experimented with practical alchemy but is also credited as one of the four female alchemists who could produce the Philosopher's stone. Some writers consider her to be the inventor of the alembic, a distillation apparatus. Cleopatra the Alchemist appears to have been active in Alexandria in the 3rd century or 4th century A.D. She is associated with the school of alchemy typified by Mary the Jewess and Comarius. These alchemists used complex apparatus for distillation and sublimation.Taylor, F. Sherwood. “A Survey of Greek Alchemy”. ''The Journal of Hellenic Studies'' 50 (1930): 109–139. Identity and misnomers Cleopatra is a pseudonym for an unknown author or group of authors. She is not the same person as Cleopatra VII. Nonetheless, she is referred to as Cleopatra, Queen of Egypt, in some later works. One example of this can be found in ''Bas ...

Mary The Jewess
Mary or Maria the Jewess ( la, Maria Hebraea), also known as Mary the Prophetess ( la, Maria Prophetissa) or Maria the Copt ( ar, مارية القبطية, Māriyya al-Qibṭiyya), was an early alchemist known from the works of Zosimos of Panopolis () and other authors in the Greek alchemical tradition. On the basis of Zosimos's comments, she lived between the first and third centuries A.D. in Alexandria. French, Taylor and Lippmann list her as one of the first alchemical writers, dating her works at no later than the first century. She is credited with the invention of several kinds of chemical apparatus and is considered to be the first true alchemist of the Western world.. Through Zosimos many of the beliefs of Mary the Jewess can be observed. Mary incorporated lifelike attributes into her descriptions of metal such as bodies, souls, and spirits. Mary believed that metals had two different genders and by joining these two genders together a new entity could be made. By j ...

Pot Still
A pot still is a type of distillation apparatus or still used to distill liquors such as whisky or brandy. In modern (post-1850s) practice, they are not used to produce rectified spirit, because they do not separate congeners from ethanol as effectively as other distillation methods. Pot stills operate on a batch distillation basis (as contrasted with Coffey or column stills, which operate on a continuous basis). Traditionally constructed from copper, pot stills are made in a range of shapes and sizes depending on the quantity and style of spirit desired. Spirits distilled in pot stills top out between 60 and 80 percent alcohol by volume (ABV) after multiple distillations. Because of this relatively low level of ABV concentration, spirits produced by a pot still retain more of the flavour from the wash than distillation practices that reach higher ethanol concentrations. Under European law and various trade agreements, cognac (a protected term for a variety of brandy pr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Muhammad Ibn Zakariya Al-Razi
Abū Bakr al-Rāzī (full name: ar, أبو بکر محمد بن زکریاء الرازي, translit=Abū Bakr Muḥammad ibn Zakariyyāʾ al-Rāzī, label=none), () rather than ar, زکریاء, label=none (), as for example in , or in . In modern Persian his name is rendered as fa, ابوبکر محمدبن زکریا رازی, label=none (see ), though instead of fa, زکریا, label=none one may also find fa, زکریای, label=none (see ). , often known as (al-)Razi or by his Latin name Rhazes, also rendered Rhasis, was a Persian physician, philosopher and alchemist who lived during the Islamic Golden Age. He is widely regarded as one of the most important figures in the history of medicine, and also wrote on logic, astronomy and grammar. He is also known for his criticism of religion, especially with regard to the concepts of prophethood and revelation. A comprehensive thinker, al-Razi made fundamental and enduring contributions to various fields, which he recor ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Distilled Beverages
Liquor (or a spirit) is an alcoholic drink produced by distillation of grains, fruits, vegetables, or sugar, that have already gone through alcoholic fermentation. Other terms for liquor include: spirit drink, distilled beverage or hard liquor. The distillation process concentrates the liquid to increase its alcohol by volume. As liquors contain significantly more alcohol (ethanol) than other alcoholic drinks, they are considered 'harder'; in North America, the term ''hard liquor'' is sometimes used to distinguish distilled alcoholic drinks from non-distilled ones, whereas the term ''spirits'' is more common in the UK. Some examples of liquors include vodka, rum, gin, and tequila. Liquors are often aged in barrels, such as for the production of brandy and whiskey, or are infused with flavorings to form a flavored liquor such as absinthe. While the word ''liquor'' ordinarily refers to distilled alcoholic spirits rather than beverages produced by fermentation alone, it ...

Rose-water
Rose water ( fa, گلاب) is a flavoured water made by steeping rose petals in water. It is the hydrosol portion of the distillate of rose petals, a by-product of the production of rose oil for use in perfume. Rose water is also used to flavour food, as a component in some cosmetic and medical preparations, and for religious purposes throughout Asia and Europe. Rose syrup (not to be confused with rose hip syrup) is a syrup made from rose water, with sugar added. Gulkand in South Asia is a syrupy mashed rose mixture. Central Iran is home to the annual Golabgiri festival each spring. Thousands of tourists visit the area to celebrate the rose harvest for the production of ''golâb'' (). Iran accounts for 90% of world production of rose water. History Since ancient times, roses have been used medicinally, nutritionally, and as a source of perfume. Rose perfumes are made from rose oil, also called ''attar of roses'', which is a mixture of volatile essential oils obtained by ...

Pictogram
A pictogram, also called a pictogramme, pictograph, or simply picto, and in computer usage an icon, is a graphic symbol that conveys its meaning through its pictorial resemblance to a physical object. Pictographs are often used in writing and graphic systems in which the characters are to a considerable extent pictorial in appearance. A pictogram may also be used in subjects such as leisure, tourism, and geography. Pictography is a form of writing which uses representational, pictorial drawings, similarly to cuneiform and, to some extent, hieroglyphic writing, which also uses drawings as phonetic letters or determinative rhymes. Some pictograms, such as Hazards pictograms, are elements of formal languages. "Pictograph" has a different definition in the field of prehistoric art (which includes recent art by traditional societies), where it means art painted on rock surfaces. This is in comparison to petroglyphs, where the images are carved or incised. Such images may or ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Metaphor
A metaphor is a figure of speech that, for rhetorical effect, directly refers to one thing by mentioning another. It may provide (or obscure) clarity or identify hidden similarities between two different ideas. Metaphors are often compared with other types of figurative language, such as antithesis, hyperbole, metonymy, and simile. One of the most commonly cited examples of a metaphor in English literature comes from the " All the world's a stage" monologue from '' As You Like It'': All the world's a stage, And all the men and women merely players; They have their exits and their entrances And one man in his time plays many parts, His Acts being seven ages. At first, the infant... :—William Shakespeare, '' As You Like It'', 2/7 This quotation expresses a metaphor because the world is not literally a stage, and most humans are not literally actors and actresses playing roles. By asserting that the world is a stage, Shakespeare uses points of comparison between the world a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
