What is silver plating?

The so-called "silver plating" is to decorate the silver with gold plating. Gilding is one of the decorative techniques of ancient metal crafts. Gold plating with gold amalgam is called "fire gold plating" in modern times. ? This technology appeared in the Spring and Autumn Period and the Warring States Period. Han dynasty called it "golden painting" or "yellow painting".

Gold plating and silver plating is a process for processing bronze products, which is often used in the Spring and Autumn Period and the Warring States Period. Charcoal, heavy metals and mercury are burned and then coated on the surface of bronzes. Because mercury is a volatile chemical substance (Hg), it naturally volatilizes after standing for a period of time after painting.

Bronzing is a traditional craft in our country, which was summarized and created by the ancient working people in production and labor. China's gold plating technology began in the Warring States Period, and China was also the first country in the world to use this technology.

From the unearthed cultural relics, it is confirmed that the ancients had mastered the gold plating technology during the Warring States period. Judging from the "Chu Daguan Bad Clock" unearthed from the tomb of Liu Sheng, Zhongshan King in Mancheng, Hebei Province, its gold plating technology is quite mature. The technology of bronzing can't be mastered at once. It was created by the ancient working people in China through pioneering research and continuous exploration and summary.

Judging from the "Ding" unearthed from Chu Tomb in Changtaiguan, Xinyang, the shape has the characteristics of the early Warring States period, and the gold-plated copper belt hook unearthed from this tomb is also an artifact of the early Warring States period. Therefore, some experts and scholars believe that the initial time of gold-plating technology should be set at the end of the Spring and Autumn Period or the early Warring States Period.
