Encyclopedia article on dye-stuffs from Chambers's Encyclopedia (1881). It lists the principal natural dyes of animal and vegetable origin, such as cochineal, kermes, lac, madder, indigo, logwood, fustic, weld, woad and quercitron, with the colours each yields. It then covers the newer coal-tar (aniline) colours, including mauve, magenta, roseine, violine and picric acid, with their chemical preparation. It ends with methods of applying them to silk, wool and cotton, and in calico printing.
