Description

A mixture of pigment in drying oil emulsified with gum arabic and glycerin to produce a bright, transparent paint. Gum arabic and other polysaccharides, such as gum tragacanth and fruit gums, have been used as water-soluble paint media for many centuries. To form gum temperas, the water-soluble gums are combined with drying oils, and sometimes natural resins, to form milky emulsions. Glycerin is often added to keep the mixture from separating. Even with the addition of oil or resin, the dry gum tempera paint films are water-sensitive and should be treated similar to watercolors.
