The Alembic is a Vessel usually of Copper tined, which serves for, and is essential to all Operations in the Distillery.

There are several Sorts of Alembics, all different, either with regard to Matter or Form. As, the common Alembic with a Refrigeratory, the earthen and the glass Alembic, the Balneum Mariæ, and the Vapour-Bath Alembic.

Every one of these being of a different Construction, are also used in different Operations.

The common Alembic consists principally of two Parts, the lower Part called the Body, and the upper termed the Head.

The Body consists of two Pieces, the lower called the Cucurbit, and the upper the Crown. The Cucurbit or lower Part of the Body, is a kind of Receptacle proportioned to the Size of the Alembic, in which the Bodies to be distilled are placed.

The Crown, or upper Part of the Body, is also another Part of the Alembic; and is that Part of the Body to which the Head is immediately luted. But an Idea of these several Alembics will be much better attained from the following Figures, which represent them much stronger to the Imagination than is possible to be done by Words.

Fig. 1. Is a common Alembic, as it appears before it is placed in a Furnace, where a is the Bottom, b the Crown, c the Head.

Fig. 2. Is the Body without the Head; a the Rim or Top of the Crown where the Head is luted.

Fig. 3. The Head; a the Rim where it is to be luted to the Body; b the Nose, or End which is luted into the Worm.

Fig. 4. The Worm, as it appears when out of the Tub in which it is fixed when in use; a the End into which the Still Head is inserted, b that which conveys the Liquor into the Receiver.
