Casein is a quick-drying, aqueous medium using a milk-based binding agent, and is one of the most durable mediums known to man. Nine thousand year old Casein cave paint-ings have been discovered in Asia, and later, the medium was used by Byzantine, Roman and Renaissance artists including the Old Masters.

In 1933, Casein pigments in tubes were developed by Ramon Shiva who relied on the expertise of the artists who used them to help perfect his high-quality paints. Casein paints can be used to create a variety of effects from the rich opaques of oil to thin watercolor washes. Casein paints may be applied to almost any rigid, non-oily sur-face such as canvas panel, illustration board, heavy watercolor paper, plaster, metal, wood, masonite, or canvas, or linen mounted on masonite. Because Casein has an exceptional integrity of color and always dries to a perfect matte finish, it is unexcelled for art reproduction. The velvety matte finish can also be buffed to a satin sheen or varnished to produce a resemblance to oils. Over time, Casein pigments become resistant to mois-ture and as history has proven, the medium has a durability and permanence which has easily stood the test of time.
