Description

A destructive corrosion process that occurs on Copper and Bronze objects. Bronze disease occurs from the reaction of chlorides on copper in the presence of moisture and oxygen. It produces blue-green powdery spots usually containing Atacamite (copper oxychloride). Once initiated, the reaction is cyclic making it difficult to halt, unless the reacting compounds (chloride, water, oxygen) are eliminated.
