Abstract
In this study, copper coin and copper spoon were mainly investigated as the bronze objects in Koryo-Lee Dynasties. The relationship of composition of base alloy and corrosion film, metallograpy of structure, some of corrosion tests, and reduction techniques of corrosion film etc, were carried out in this study. The composition of bronze objects were mainly Cu, Pb, Zn, and Sn, and these compositions were different by the age produced. Black patina is better protective film compared with green patina, and tendency of its formation is gradually increased by the increasing of Sn content.
