Traité complet des propriétés, de la préparation et de l'emploi des matières tinctoriales et des couleurs ...
A French treatise on dyestuffs, their preparation and use, compiled by the chemist J. C. Leuchs and the physicist E. Péclet and published in Paris in 1829 by De Malher. Its single plate is a technical diagram sheet of dyeing apparatus, with vats, pipes, furnaces and stacked trays drawn in fine black line on cream paper. A designer might take from it the clean, schematic plate layout and the numbered, labelled diagram style of early industrial engraving.
