Description

A size or glaze made from egg white. Glair is prepared by beating egg white with a little water and allowing it to stand overnight. Some recipes add a small amount of vinegar. Glair becomes tackier, and more odorous, the longer it stands. Glair has been used as a sizing for gilding, as a binder for manuscript illumination paints, and as a thin glaze. It is a weak binder and cracks in low humidity.
