Leçons de chimie appliquée à la teinture
A Paris textbook of 1829 by chemist Michel Eugène Chevreul, published by Pichon et Didier, teaching applied chemistry to dyers and textile workers. Its pictures are plain line diagrams of laboratory apparatus: a tall graduated cylinder with a sloped tube, a bent-tube gas collection set, and a row of wash bottles on a flask, all drawn in fine black outline on tan paper, useful to a designer for simple scientific schematic motifs.
