Dye

Main article:  CochinealA deep crimson dye is extracted from the female cochineal insects. Cochineal is used to produce , and other red tints. The colouring comes from . Cochineal extract's natural carminic-acid content is usually 17–23%. The insects are killed by immersion in hot water (after which they are dried) or by exposure to sunlight, steam, or the heat of an oven. Each method produces a different colour that results in the varied appearance of commercial cochineal. The insects must be dried to about 30 percent of their original body weight before they can be stored without decaying. It takes about 70,000 insects to make one pound of cochineal dye.

There are two principal forms of cochineal dye: cochineal extract is a colouring made from the raw dried and pulverised bodies of insects, and carmine is a more purified colouring made from the cochineal. To prepare carmine, the powdered insect bodies are boiled in or a solution, the insoluble matter is removed by filtering, and is added to the clear salt solution of carminic acid to precipitate the red salt. Purity of colour is ensured by the absence of . Stannous chloride, , , or may be added to regulate the formation of the precipitate. For shades of , is added to the alum.
