An alembic (from , originating from , 'cup, beaker') is an alchemy still consisting of two vessels connected by a tube, used for distillation of liquids.
In the case of another distilling vessel, the retort, the "cap" and the "cucurbit" have been combined to form a single vessel. The anbik The complete distilling apparatus consists of three parts: the "cucurbit" ( ḳarʿa), the "head" or "cap" ( anbīḳ) and the "receiver" ( ḳābila). 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 still, used to produce distilled beverages.
Alembic drawings appear in works of Cleopatra the Alchemist (3rd century C.E.), Zosimos of Panopolis (c. 300 C.E.), and Synesius (c. 373 – c. 414 C.E.). There were alembics with two (dibikos) and three (tribikos) receivers. According to Zosimos of Panopolis, the alembic was invented by Mary the Jewess.
The anbik is described by Ibn al-Awwam in his Kitab al-Filaha ( Book of Agriculture), where he explains how rose-water is distilled. Amongst others, it is mentioned in the Mafatih al-Ulum ( Key of Sciences) of Khwarizmi and the Kitab al-Asrar ( Book of Secrets) of al-Razi. Some illustrations occur in the Latin translations of works which are attributed to Pseudo-Geber.
