What is Silver Corrosion? Definition from Corrosionpedia

Corrosionpedia explains Silver Corrosion. When silver is attacked by sulfur, the chemical reaction leaves the metal with a brownblack patina which does not result in much metal loss. The attack also results in black fissures and pits. The rate of pitting attack is generally slow, but can increase if a stronger acid or salts are present.
