Artist & Craftsman Supply Market Share Analysis for July 2026

Jack Richeson Casein Paints use a milk-based binding agent that is water-soluble. Because it dries to an even, velvety matte finish, it is highly suited for reproduction and was very popular among commercial artists, especially before the invention of acrylics. A forgiving medium, casein can be reworked liberally by simply rubbing it with a damp cloth, wet brush, or even an eraser. A dry casein painting can also be buffed to a glossy finish with a soft cloth, giving it an appearance similar to that of an oil painting. These paints may be applied to almost any rigid, non-oily surface such as canvas panel, illustration board, heavy watercolor paper, plaster, metal, wood, masonite, or canvas mounted on panel. Casein paintings have proven to be very archival especially on rigid supports, but beware of applying heavily to flexible supports, like stretched canvas, as it is prone to cracking. Available in 5 oz and 37 ml tubes. Choose from available colors.
