What is gold foil and what is its use?

Gold foil is a thin sheet hammered with gold. Modern science and technology will carry forward the traditional gold foil technology and develop new varieties of gold foil, such as high-tech laser shallow carving and bronzing on gold foil with purity of 99%, which has the value of preservation, collection, commemoration and appreciation.

One or two (365,438+0.25 g) pure gold can be hammered into gold foil with a thickness of one tenth of a millimeter and an area of 65,438+06.2 square meters due to its good ductility and plasticity. Gold has the characteristics of stable nature, permanent discoloration, oxidation resistance, moisture resistance, corrosion resistance, mildew resistance, insect resistance and radiation resistance. Gold foil made of gold is widely used. Gold foil is a traditional handicraft of the Chinese nation, which originated in the Eastern Jin Dynasty, matured in the Southern Dynasties and was popular in Song, Qi, Liang and Chen Dynasties. Today, the Longtan area (Jiangning) in Nanjing is the birthplace of gold foil, which is said to have a history of nearly 1700 years. The inscription on the tomb of Cixi in Dongling, Beijing is a typical gold foil product.
