Process
Metals that are made into metal leaf need to be highly malleable. For malleability in Cryptography, see Malleability (cryptography. They can be pounded into sheets well below a micrometre in thickness without breaking or tearing. A micrometre ( American spelling: micrometer; symbol µm) is one millionth of a Metre, or equivalently one thousandth of a Millimetre The typical thickness of gold leaf is about 100 nanometres or 0. A nanometre ( American spelling: nanometer, symbol nm) ( Greek: νάνος nanos dwarf; μετρώ metrό count) is a 0001 mm[1]. When made by hand, small pieces of metal are placed between sheets of parchment and pounded repeatedly with wooden mallets. Parchment is a thin material made from Calfskin, Sheepskin or goatskin. As the metal thins out, it forms large sheets. These sheets are divided and the process repeated. The final sheets of metal are trimmed, cut to various sizes, and sandwiched between sheets of paper to protect them. At a thickness of 100 nm, one square metre of gold leaf corresponds to 0.

A cubic centimetre or cubic centimeter (symbol cm3 —the abbreviation cc, though widely used is deprecated is a commonly used unit of Volume For other uses of the words gram or gramme see Gram (disambiguation. In Imperial measurements, one ounce (28 g) of gold corresponds to about 200 square feet (about 20 m2) of gold leaf.

Uses
Decoration
Metal leaf is most often used for decoration. Before the discovery of electroplating, it was the only cost effective way to gild statues, rooftops or other objects. Electroplating is the process of using electrical current to reduce Cations of a desired material from a solution and coat a conductive object Gilding is the art of applying a thin layer of gold simulated gold or other metal to a surface A good example of exterior use of gold leaf is on the Dome and the statue of Mary atop the Main building on the campus of the University of Notre Dame, in South Bend, IN

Gilding is the art of applying a thin layer of gold simulated gold or other metal to a surface Gold leaf is available in a wide variety of karats and shades. The KARAT (abbreviation "K" or 'Kt' or "KP" for Karat Plumb is a measure of the Purity of Gold Alloys. 23-karat gold is the most commonly used.
Gold leaf is sometimes confused with metal leaf but they are different products. The term metal leaf is normally used for thin sheets of metal of any color that do not contain any real Karat gold. 24 Karats is pure gold. Real yellow gold leaf is about 92% pure gold. Silver colored white gold is approximately 50% pure gold.
Layering gold leaf over a surface is sometimes called gold leafing, and is a very common form of gilding. Gilding is the art of applying a thin layer of gold simulated gold or other metal to a surface

Water gilding
Traditional water gilding is the most difficult and highly regarded form of gold leafing. It has remained virtually unchanged for hundreds of years, and is still done by hand.
