Gold leaf
Description
Extremely thin sheets of Gold that are used for gilding. Gold leaf has been used since at least 2600 BCE (Hatchfield and Newman 1991). It is prepared by interleaving thin plates of gold between layers of gold-beater's skin which are then hammered until the malleable metal is spread to a fine continuous film thickness of about 0.1 micrometer. Gold leaf is typically cut in 3 inch squares and sold in books containing 25 sheets. Standard gold leaf is 23.5 carat; other types of gold leaf are lemon gold (18.5 carat) and pale gold (16 carat). The latter two are alloyed with silver and are thicker and easier to handle. Gold leaf is used for gilding furniture, frames, and plaster. It is also used for gold lettering and other types of decoration.
