Description
A term whose primary meaning in art, refers to the ellipsoidal shell and embryonic contents produced by birds. For paintings, the egg contents are used as a tempera medium. The whole egg, yolk, or white may be used sometimes mixed with oil and/or resin. The egg yolk is a stable emulsion of an aqueous liquid with an oily, proteinaceous medium which dries quickly into a hard, insoluble film. Egg white, or glair, has been used as a medium for illuminated manuscripts. It is also used as a size for attaching gold leaf. Albumen is the adhesive substance of egg white. As a pure film, albumen is clear, brittle, and water soluble. Water solubility can be decreased by heating or adding tannin. The exterior of a bird egg is covered with a brittle shell composed of keratin and calcite.
Synonyms and Related Terms
Ei (Deut.); huevo (Esp.); œuf (Fr.); uovo (It.); ei (Ned.); jajo (Po.); ovo (Port.); ägg (Sven.)
Other Properties
Miscible with water when fresh. Insoluble in water after heating.
