Why does silver turn black?
First, because everyone's endocrine and physical condition are different, some people's sweat contains more acid, some people have less, and some people's body fluids have high sulfur content. These are all substances that cause the surface of silver ornaments to turn black, so everyone will have different results when wearing silver ornaments, and some people will be as bright as new after wearing them for half a year.
Second, sulfur, nitric acid and oxides in air and other substances (such as eggs and cosmetics) have a certain corrosive effect on silver. Silver jewelry has been worn for a long time, sulfur and silver.
When combined, a layer of black silver sulfide film will be formed on the surface of silver jewelry, which will appear as some tiny spots at first, and then spread into pieces to form what people usually call silver scales, which will turn black and affect the surface luster of silver jewelry.
