Distillation By Means of A Metallic Still, 1892

Illustration from an 1892 Chemistry book for distillation by means of a metallic still. Retort and attachments sits on a furnace; neck is connected to coils immersed in a container (cutaway for view) of cold water. The liquid in C is heated by the fire F. The vapors rise through the head A and pass by the tube T to the worms placed in a vessel through which a current of cold water flows by means of tubes D and P. In chemistry, distillation means the separating of the constituents of a liquid by boiling it and then condensing the vapor that results. Distillation can be used to purify water or other substances, or to remove one component from a complex mixture, as when gasoline is distilled from crude oil or alcohol from a mash. When water is purified by distillation, it is boiled in a container, and the steam is sent into cooling tubes. The steam is condensed and then collected as purified water in a second container. The impurities in the water are left behind in the first container and can be discarded
