A hand-colored technical illustration shows a distillation apparatus. On the left, a cylindrical red-brick furnace labeled A contains a bulbous copper vessel labeled B. Above this vessel sits a matching cap labeled C. A copper-colored pipe labeled D, called the serpent or coil, emerges from the top of the cap. It forms a bridge with two right-angle joints and enters a large wooden cooling tub bound by dark hoops. The pipe ends at a spout on the right side of the tub, where a green collection bag is attached to catch the distilled oil.
