After synthetic pigments and dyes such as alizarin were invented in the late 19th century, natural-dye production gradually diminished. We'll be exploiting this property to create different colors for painting so let's get started! This dyeing process is a little different than most in that you will want to let your cochineal sit in the water as long as possible. Stannous chloride, citric acid, borax, or gelatin may be added to regulate the formation of the precipitate.
