Bronze disease Bronze disease Bronze disease is the irreversible and nearly inexorable corrosion process occurring when chlorides come into contact with bronze or other copper-bearing alloys. It occurs as a dark green or a lighter fuzzy green coating on copper, bronze, and other copper-bearing alloys generally due either to contamination by salt water or after burial in dirt (as chloride salts are generally present in soil to some degree). If not treated, complete destruction of the affected artifact is possible. Transfer of chlorides from the contaminated artifact to other artifacts can spread the condition. Bronze disease is the chloride corrosion of cupreous
