Matters needing attention and main points of silver:
Black, usually because of contact with sulfide. The chemical properties of silver are relatively active, and it is easy to react with chemicals containing sulfur and other elements to form compounds of sulfur and silver. After a long time, this compound will slowly form a layer of black silver sulfide film on the surface of silver ornaments, which first appears as some tiny spots and then gradually spreads, called "silver scale" or "silver mold".
When silver comes into contact with sulfur-containing food, it will undergo an oxidation reaction and become yellow and black. Fish, meat, eggs, peanuts, preserved eggs, lean porridge, beer and other foods all contain more sulfur. Silver tableware will change color when exposed to these ingredients under heating. A small amount of silver sulfide is harmless to the body, but for the maintenance of silver tableware, these foods should be avoided.
