Gilding
Sizing or size is a term used for any substance which is applied to a surface before gilding in order to ensure adhesion of the thin gold leaf to the substrate. Egg whites have often been used as sizing; the Ancient Egyptians sometimes used blood. Other commonly used for gold leaf sizing are rabbit skin glue diluted and heated in water (water gilding), and boiled linseed oil (oil gilding); modern materials include polyvinyl acetate.
