Traité de la peinture au pastel, du secret d'en composer les crayons, & des moyens de le fixer : avec l'indication d'un grand nombre de nouvelles substances propres à la peinture à l'huile, & les moyens de prévenir l'altération des couleurs
A French treatise on pastel painting, published in Paris in 1788 by Defer de Maisonneuve, with André-Charles Cailleau named as co-author, aimed at artists who make and fix pastel crayons. The pictures are small black woodcut-style tailpieces and vignettes of flowers, a vase and a plant sprig, printed as decorative breaks between sections, with a designer able to borrow their compact botanical forms for ornament.
