The jewelry processing factory said that silver is a relatively active precious metal, which is very easy to react with sulfur or hydrogen chloride in the air and turn into grayish black silver sulfide. This is why silver jewelry will turn black after use. The silver jewelry used for a long time is subject to very little friction on the surface, and this kind of blackening is more serious after placement. Many silver jewelry is often made of silver alloy copper, and this kind of silver jewelry should pay more attention to corrosion resistance. In order to prevent silver jewelry from blackening, there are three common methods:

1. Surface treatment: this is also an industrial production mode, which is not easy for me to choose.

2. Surface coating solution: Apply a layer of transparent varnish on the surface of the jewelry to block the silver from the external gas. The general wearer can use colorless transparent nail polish as the coating in the jewelry, which is especially simple and does not harm the glossiness of the silver jewelry. According to the actual damage condition of the wearer, the interval time of applying nail polish or transparent paint is determined. Because the natural environment in the work is different, those that are damaged quickly can be painted once a week, while those who do not touch hard blocks or rarely wear ornaments to do housework can be painted every half a month or more. When storing unwanted ornaments for a long time, surface coating should also be carried out.

3. Always keep silver jewelry clean and dry. It is better not to let silver jewelry touch sulfur containing organic chemical vapor, nor clean silver jewelry with sulfur soap. Silver jewelry should be placed in dry and airtight areas when it is not needed.

The above is the silver jewelry maintenance method explained by the jewelry processing factory. I hope it will be helpful to you after reading it.
