Gold paste is an ancient art form that is widely used in aristocratic ornaments and Buddhist statues. It is hard to imagine how artisans hammered gold bars into slivers of gold foil as thin as an onion skin, and how they attached them to objects.

The production process involves more than 10 procedures. One gram of gold can be made into about 0.5 square meters of pure gold foil, with a thickness of only 0.12 microns. It is lighter than a feather, thinner than an onion skin and softer than silk. These real gold foils can keep their luster for at least 70 years.

A special glue is needed to create the gold paste. The viscosity of the glue and its thickness are the key to its success. The humidity of the air determines the amount of time it takes to dry.
