Top best answers to the question «Does pure silver turn black»

Silver becomes black because of hydrogen sulfide (sulfur), a substance that occurs in the air. When silver comes into contact with it, a chemical reaction takes place and a black layer is formed… The oxidation of silver jewelry is a sign that it is really silver. Other (noble) metals oxidize differently.

Silver turns black when kept in the air because it reacts with sulphur compounds such as hydrogen sulphide (H2S) present in air. The phenomenon is called corrosion and, for silver in particularly, is called tarnishing. The black substance formed is silver sulphide.

Silver turning black on the skin is caused by a chemical process called oxidation which is not a property of pure silver but the copper component in it. Oxidation happens when the protective coating wears off and the copper base metal is exposed to the air.

Silver becomes black because of hydrogen sulfide (sulfur), a substance that occurs in the air. When silver comes into contact with it, a chemical reaction takes place and a black layer is formed. Silver oxidizes faster in places with a lot of light and high humidity. Also contact with products like cosmetics, hair spray, perfume, deodorant, body ...

Make-up present on the skin or clothing is the most common cause of blackening or smudging. Cosmetics often contain chemical compounds which are harder than the jewelry itself.
