Q: What is the common "vulcanization treatment" in Nepal jewelry? A: Actually, when silver jewelry turns black, "oxidation" is a common folklore. Oxidation refers to the interaction of substances with oxygen, but the blackening of silver (jewelry) is related to the "sulfur" in the air, so the surface of silver (jewelry) The black substance (may be brown, light brown or dark brown or brown), this is "silver sulfide". Generally silver (jewelry) will turn black and lose its luster if it is not properly maintained, so the correct name should be "sulfide", which is the reaction of hydrogen sulfide in the air or sulfur dioxide in water, so sulfide is formed on the surface of silver (jewelry) silver.
