A collection of technical drawings illustrates the chemical apparatus described in the list. At the top left, labeled A, is a cylindrical beige furnace resting on a wooden tripod, featuring two circular openings labeled B for the top and C for the bottom. At the top right, labeled D and E, are two reddish-orange ceramic vessels. Vessel D is a pear-shaped flask positioned above vessel E. Vessel E is a receiver with a wide top and two side spouts: a short, upper spout labeled F and a longer, lower spout labeled G.
