Alembic
An alembic (from , originating from , '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 "" (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" (, ) * 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'' (the Arabic word ''raʾs'' means "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 alembic is the pot ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Aludel
An aludel ( from Greek language, Greek , 'smoky, sooty, burnt-colored') is a Sublimation (phase_transition), subliming pot used in alchemy. The term refers to a range of earthen tubes, or pots without bottoms, fitted one over another, and diminishing as they advance towards the top. The lowest is adapted to a pot, placed in a furnace, wherein the matter to be sublimed is placed. At the top is a head to retain the Precipitation (chemistry), flowers, or condensation, which ascends. An aludel was used as a condenser in the sublimation process and thus came to signify the end-stages of transformation and the symbol of creation. Also called the Hermetic Vase, the Philosopher's Egg, and the Vase of the Philosophy. Description The contrivance serves to sublimate Mercury (element), mercury (zaybak), sulfur, orpiment (zarnīkh) and the like. It is made of glass or clay (fakhkhār) and consists of two tubes (ziḳḳ, actually hoses) fitted together. The mineral is put in the lower ...

Still
A still is an apparatus used to distillation, distill liquid mixtures by heating to selectively Boiling, boil and then cooling to Condensation, condense the vapor. A still uses the same concepts as a basic Distillation#Laboratory_procedures, distillation apparatus, but on a much larger scale. Stills have been used to produce perfume and medicine, water for injection (WFI) for pharmaceutical use, generally to separate and purify different chemicals, and to produce distilled beverages containing ethanol. Application Since ethanol boiling point, boils at a much lower temperature than water, simple distillation can separate ethanol from water by applying heat to the mixture. Historically, a copper vessel was used for this purpose, since copper removes undesirable sulfur-based compounds from the alcohol. However, many modern stills are made of stainless steel pipes with copper linings to prevent erosion of the entire vessel and lower copper levels in the waste product (which in ...

Distillation
Distillation, also classical distillation, is the process of separating the component substances of a liquid mixture of two or more chemically discrete substances; the separation process is realized by way of the selective boiling of the mixture and the condensation of the vapors in a still. Distillation can operate over a wide range of pressures from 0.14 bar (e.g., ethylbenzene/ styrene) to nearly 21 bar (e.g., propylene/propane) and is capable of separating feeds with high volumetric flowrates and various components that cover a range of relative volatilities from only 1.17 ( o-xylene/ m-xylene) to 81.2 (water/ ethylene glycol). Distillation provides a convenient and time-tested solution to separate a diversity of chemicals in a continuous manner with high purity. However, distillation has an enormous environmental footprint, resulting in the consumption of approximately 25% of all industrial energy use. The key issue is that distillation operates based on phase changes, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Retort
In a chemistry laboratory, a retort is a device used for distillation or dry distillation of substances. It consists of a sphere, spherical vessel with a long downward-pointing neck. The liquid to be distilled is placed in the vessel and heated. The neck acts as a condenser (laboratory) , condenser, allowing the vapors to condense and flow along the neck to a collection vessel placed underneath. In the chemical industry, a retort is an airtight vessel in which substances are heated for a chemical reaction producing gaseous products to be collected in a collection vessel or for further processing. Such industrial-scale retorts are used in shale oil extraction , shale-oil extraction, in the production of charcoal and in the recovery of Mercury (element) , mercury in gold-mining processes or from hazardous waste. A process of heating oil shale to produce shale oil, oil shale gas, and spent shale is commonly called retorting. Airtight vessels to apply pressure as well as heat a ...

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 (in contrast to 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 produced in the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cleopatra The Alchemist
Cleopatra the Alchemist (Greek: Κλεοπάτρα; fl. ) was a Greek alchemist, writer, 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 ''Basilica Philosophic ...

Muhammad Ibn Zakariya Al-Razi
Abū Bakr al-Rāzī, also known as Rhazes (full name: ), , 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. However, the religio-philosophical aspects of his thought, which also included a belief in five "eternal principles", are fragmentary and only reported by authors who were often hostile to him. A comprehensive thinker, al-Razi made fundamental and enduring contributions to various fields, which he recorded in over 200 manuscripts, and is particularly remembered for numerous advances in medicine through his observations and discoveries. An early proponent of experimental medicine, he became a successful doctor, and served as chief physician of Baghdad and Ray hospitals.. As a te ...

Pseudo-Geber
Pseudo-Geber (or "Middle Latin, Latin pseudo-Geber") is the presumed author or group of authors responsible for a corpus of pseudepigraphic alchemical writings dating to the late 13th and early 14th centuries. These writings were falsely attributed to Jabir ibn Hayyan (died 816, Latinisation of names, Latinized as Geber), an early Alchemy, alchemist of the Islamic Golden Age. The most important work of the Latin pseudo-Geber corpus is the ("The Height of the Perfection of Mastery"), which was likely written slightly before 1310. Its actual author has been tentatively identified as Paul of Taranto. The work was influential in the domain of alchemy and metallurgy in late medieval Europe. The work contains experimental demonstrations of the corpuscularianism, corpuscular nature of matter that were still being used by seventeenth-century chemists such as Daniel Sennert, who in turn influenced Robert Boyle. The work is among the first to describe nitric acid, aqua regia, and aqua fo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Emoji
An emoji ( ; plural emoji or emojis; , ) is a pictogram, logogram, ideogram, or smiley embedded in text and used in electronic messages and web pages. The primary function of modern emoji is to fill in emotional cues otherwise missing from typed conversation as well as to replace words as part of a logographic system. Emoji exist in various genres, including facial expressions, expressions, activity, food and drinks, celebrations, flags, objects, symbols, places, types of weather, animals, and nature. Originally meaning pictograph, the word ''emoji'' comes from Japanese + ; the resemblance to the English words ''emotion'' and ''emoticon'' is False cognate, purely coincidental. The first emoji sets were created by Japanese portable electronic device companies in the late 1980s and the 1990s. Emoji became increasingly popular worldwide in the 2010s after Unicode began encoding emoji into the Unicode Standard. They are now considered to be a large part of popular culture ...
