Facing a glowing furnace at left, a bearded alchemist in green with red cap looks at flask of green liquid with young assistant in red singlet; laboratory apparatus in foreground and background; a pufferfish hangs from the ceiling; two doves on window sill and through window a castle atop a mountain. Seated grey bearded man three quarter view facing right, in black coat with fur collar and cuff, black hat on head, sits at red carpet covered table of books, papers, copper pitcher and dark ceramic jar, holds in left hand a gold scale. Resting on a bench in front of table, large book and jug with blue glaze marks and glass.
