1. Reasons for silver jewelry turning black
The blackening of silver ornaments is a normal natural phenomenon, because sulfur and oxides in air and other natural media have a certain corrosive effect on silver. When silver ornaments are worn for a long time, the combination of sulfur and silver will form a black silver sulfide film on the surface of silver ornaments, which will begin to show as some tiny spots. After the vulcanization phenomenon intensifies, it will slowly spread into pieces, forming what people usually call silver scale, turning black, affecting the surface luster of silver ornaments, which is often mistaken for fading.
The chemical reaction equation is: 4Ag+H2S+O2=2Ag2S+2H2O

How to clean silver jewelry after vulcanization?
Squeeze a little toothpaste, add a little water to knead a rich foam, wipe with a soft cloth until bright, the gap can be brushed with a fine soft toothbrush, and then rinsed with water.

3.  How to maintain silver jewelry in daily life?
The best way to maintain silver jewelry is to wear it every day, because the oil of the human body will make the silver glow warm and natural (of course , there are exceptions, some people’s sweat itself contains ingredients that make the silver black).
