Alchemist in Green Using Bellows

An alchemist wearing a green robe uses a pair of bellows to control the heat of the fire beneath his crucible. Other vessels sit on the furnace at his side, and to his left a large still head for distillation rests over a portable stove. In the background are three men conversing, one examining a flask of liquid, likely performing a urinoscopy. This painting is a modern copy after an original by the seventeenth-century painter David Teniers the Younger (1610-1690), who was famed for his representations of alchemists at work in the laboratory.
