Metal leaf
A metal leaf, also called composition leaf or schlagmetal, is a thin foil used for gilding and other forms of decoration.[1] Metal leaves can come in many different shades, due to the composition of the metal within the metal leaf. Examples of this variation of shades in metal leaves can be found in Ancient Egyptian gold leaves, as the silver content within the gold leaves could make them appear bright yellow or paler shades of yellow.[2] Some metal leaves may look like gold leaf but do not contain any real gold. This type of metal leaf is often referred to as imitation leaf.
Metal leaves are usually made of gold (including many alloys), silver, copper, aluminium, brass (sometimes called "Dutch metal" typically 85% Copper and 15% zinc) or palladium, sometimes also platinum.
Vark is a type of silver leaf used for decoration in Indian cuisine.
Goldbeating, the technique of producing metal leaves, has been known for more than 5,000 years. A small gold nugget 5 mm in diameter can be expanded to about 20,000 times its initial surface through hammering, producing a gold foil surface of about one half square meter with a thickness of 0.2–0.3 μm.
