Egg tempera

Description

A tempera paint prepared with the whole Egg, the yolk, or the white as a medium. Egg yolk is a natural emulsion containing a homogeneous mixture of lipids and water. Lecithin and Albumen act as emulsifying agents. Traditionally, the pure egg yolk, with its surface delicately dried by rolling in the palms, was poured from its yolk sac then ground with pigments. Vinegar or Clove oil was sometimes added as a preservative. Other recipes use whole egg, as an emulsifier, mixed with Linseed oil and water (see Tempera grassa). Occasionally a natural resin was also added. Some sulfur containing pigments, Vermilion, and cadmium colors, are incompatible with egg tempera (Doerner, 1934).
