Therefore, most people are worried that the presence of mercury in gilt silver products is simply insignificant, and the mercury has evaporated during the high-temperature heating process. In the end, I got the gilt silver teacup in my hand, and I didn't drink any mercury when I drank water.
Such worries are unnecessary.
Gilt teacups contain trace amounts of mercury, which are harmless to humans under normal use. Because the gilding process has existed for many years from ancient times to the present, it has developed relatively maturely, but most of the time it is used to decorate the exterior of the vessel, and few people will use the gilding process.
Used inside the vessel. Therefore, it is normal to have concerns about this without knowing it.

One of the most striking features of the gilded bronze Buddha statues of the Northern Dynasties is that the Buddha statues are generally not single, the middle is the main Buddha, and there are often two Bodhisattvas next to the main Buddha and most of them are standing. The gilded bronze Buddha statue of the Northern Dynasty has a long and thin face, a clear face, closed eyes and concentrating, a high nose bridge and big ears, the hair is spiral, and the body is wearing a robe, exposing the right shoulder. Some sit cross-legged with their palms facing up.
The Buddha seat is generally a Sumeru seat or a 4-legged square seat, surrounded by flame patterns.
The gilded bronze Buddha statues of the Sui and Tang dynasties are very different from those of the Northern Dynasties, first of all, the Buddha statues of the Sui and Tang dynasties have a lotus crown on their heads, a round face, slightly chubby cheeks, a high forehead, and a monk's branch, and then a robe on the outside, a pleated skirt, hanging on the feet. The Buddha seat is a four-legged square seat, and the high bed under the cut seat has two forms: double-layer and single-layered, and the neck or backlight is generally a thicker pointed frieze.
The gilded bronze Buddha statues of the Northern Dynasties and the Sui and Tang dynasties have their own characteristics, and the identification should start from the above aspects.
For example, on December 11, the famous collector Liu Yiqian auctioned a bronze gilt Buddha statue of Kangxi for 16.5 million yuan at the Joron-Derem auction house.
Hope it helps, thank you.

Summary. Method 1: Vinylethanol Dilute formic acid solution of acrylic acid polymer:
Vinyl ethanol Acrylic polymer is a highly absorbent substance and has good water control. When mixed with dilute formic acid, a new type of paste is formed. When the new paste is placed on the green rust of the gilded object, the dilute formic acid solution in the paste will come into contact with the surface of the green rust and will not penetrate into the metal body of the object.
In this way, a very thin layer of green rust will be removed, and accordingly, the purpose of removing green rust can be achieved by treating it layer by layer. To prevent excessive removal of rust spots or partial dissolution of porous, fragile rust on the metalware, a thermoplastic resin can be applied to the parts of the object that need to be protected before the paste is used to remove rust. Once the rust has been removed, the highly absorbent substance and protective resin must be completely cleaned with hot, distilled water.
Method 2: For gilded silverware, in order not to damage or produce undesirable changes in the gilt layer and silver, formic acid can be used to remove rust and add a small amount of mercaptophenyl tetrazol. After dissolving mercaptophenyl tetrazolium with a small amount of absolute ethanol, dilute formic acid is added to prepare the solution.
On the surface of the utensils to remove the rust scale, cover the absorbent cotton moistened with the above solution, after half an hour, the green rust on the surface will gradually be dissolved and appear blue turbidity, rub the rust lightly, and then repeat it several times with a new wet cotton ball soaked in the solution. Finally, rinse and dry with distilled water.
