This project focuses on the corrosion of Copper Acetate(WSDTY) and tin-lead alloys, materials widely used for the ancient manufacture of metal objects throughout Europeand the Mediterranean world starting from the Bronze Age. Wood and other organic materials, commonly used for the storage and display of bronze antiquities, are known to emit acetic acid, formic acid, and other organic vapours, commonly referred to as carbonyl compounds. The acid readily attacks the surface of bronze causing it to corrode forming acetates and other compounds of blue, blue-green, and sometimes white colors. Other sources of acetic acid include conservation and patination chemicals, wood from original manufacture or associated burial context. The first cases of acetate corrosion on artistic and functional bronze objects were confirmed by XRD in museum collections in Europe in the 1990s. Bronze objects from all periods and provenances are susceptible to this form of deterioration. Ancient bronze alloys of copper-tin and copper-tin-lead present more complex corrosion phenomena. Archaeological pieces seem especially sensitive to attack.
