Four-page article on dyeing from the first edition of the Encyclopedia Britannica (1771). It defines the art, lists the materials used (mordants, salts, liquors, metals, colourants), and gives general observations on how dyestuffs behave. It then describes dye procedures and colour recipes for wool, silk and thread, including blacks, scarlets, blues, greens and yellows, with notes on how dyes add weight to silk.
