When dry, it forms a waterproof, absorbent layer that is ideal for Egg Tempera, Encaustic, Oils, Acrylics, Watercolours, Gouache and Casein paints, as well as other mixed media and drawing techniques. It is made from natural materials including Water, Calcium Carbonate (Whiting), Cold Pressed Linseed Oil, Milk Protein (Casein), Natural Tree Resins, Fossilized Sea Shells, Saponified Olive Oil and Salt, and can be used either straight out of the jar or thinned with water for a harder, more sandable surface. We asked Encaustic and mixed media artist, Lora Murphy, to experiment with some Sinopia Casein Gesso to see how it reacted to different materials.
