An alchemist smokes a small clay pipe as he works, stirring a substance in an earthenware jar. His assistant kneels beside the hearth at right, tending the coals of a fire beneath a distillation apparatus. Copper basins, books, and pans sit on the floor, as well as a portable furnace at the left of the scene. Through the open door, a second assistant departs.</div>
Circa 1725 – 1767
