A gold nugget of 5 mm (0.2 in) in diameter (bottom) can be expanded through hammering into a gold foil of about 0.5 m 2 (5.4 sq ft). The Toi gold mine museum, Japan.. Gold leaf is gold that has been hammered into thin sheets (usually around 0.1 μm thick [1]) by a process known as goldbeating, [2] for use in gilding.
"Overlaying" or folding or hammering on gold foil or gold leaf is the simplest and most ancient method, and is mentioned in Homer's Odyssey [8] and the Old Testament. The Ram in a Thicket (2600–2400 BC) from Ur describes this technique used on wood, with a thin layer of bitumen underneath to help adhesion.
The leaves are native gold (70–90% pure) and created through a process of annealing and hammering a single sheet of gold. [7] By pounding the sheet in different directions, the craft-smith was able to outline the shape of the leaf and create the leaf's stem that is folded into tubes and connects to the strands of beads.

A foil is a very thin sheet of metal, typically made by hammering or rolling. [1] [2] Foils are most easily made with malleable metal, such as aluminium, copper, [3] tin, and gold. Foils usually bend under their own weight and can be torn easily. [2]
Gold usually undergoes one of these processes: it could be hammered, or pounded and rolled, or just a leaf or powder. In the first case, the gold needs to reach the measure of about 1/8000 of a millimeter thick, in the second one it could be used as a normal leaf (the measure depends on the purpose) or smashed in powder.

The external edge of the brim is strengthened by a twisted square-sectioned wire, around which the gold leaf is turned upwards. The overall height is 745 mm. The hat was hammered from a gold alloy of 87.7% Gold, 9.8% Silver, 0.4% Copper and 0.1% Tin. It was made of a single piece; its average thickness is 0.6 mm.
