Q1948Cochineal dye is made by extracting carminic acid from dried female scale insects raised on prickly pear cactus, then using mordants and acidity to create reds from pink to crimson.
Indigenous dyers in the Americas cultivated cochineal and mastered the salts, acids and alkaline additions that make one source yield remarkably different colours. After the Spanish conquest, the concentrated dye became a guarded imperial commodity shipped into European textiles and paintings and onward through global trade. Its brilliance crossed borders; the wealth and power around it did not cross evenly. To find cochineal in an artwork is to find chemistry, skilled cultivation and colonial extraction compressed into colour.
