cat Casein , derived from casein milk (milk protein), is a fast, dry, water-soluble medium used by artists.

Description
It usually has a glue-like consistency, but can be attenuated with water to a level that fits the particular artist's style and desired outcome. It can be used on canvas panels, illustration boards, paper, wood and masonite. Because dry paint films are not flexible and brittle, it is not appropriate to apply to heavy impastos on flexible supporters such as canvas. Canvas laminated to board more suitable. Cat casein can be reworked and can be used for underpainting. It generally dries to matte.

Usage
Cat Casein has been used since ancient Egypt as a form of paint distemper, and is still used today. One of the qualities that artists value the case of catfish for is that, unlike gouache, it dries to even consistency, making it ideal for mural. Also, it can visually resemble oil painting more than most other water-based paints, and work well as underpainting.
Cat casein loses its solubility with time and exposure and becomes impermeable. This is best suited for inflexible surfaces, including furniture. It can be rubbed into a soft velvet layer when dry, or lacquered for gloss finishing.
Producing
The binder for casein paint is prepared by dissolving casein in alkali, usually chalk, ammonium carbonate, or borax. Casein itself is deposited from milk by the action of an acid or rennet enzyme. Lime lime works well on porous surfaces, even outdoors, although it has a short shelf life and should be used with a balanced pigment against low pH binders. Ammonium carbonate casein has the same strengths and weaknesses. Casein Borax has a shelf life of several weeks, is pH neutral, and can be used outdoors through the addition of linseed oil.
Artist Casein

Santa Clara Pueblo artist Pablita Velarde created a series of more than 70 American everyday paintings in New Mexico for the Bandelier National Monument between 1937 and 1943, mostly painted on masonit using casein paint.
Casein was widely used by commercial illustrators as a material of choice until the late 1960s when, with the advent of acrylic pain, casein became less popular. John Berkey continues to use casein in combination with acrylic in most of his paintings. Dick Tracy (1960) and Popeye (1960), two early paintings by Andy Warhol, who had been a commercial illustrator before becoming a fine artist, were painted with casein.
