| Outline of Final Research Achievements |
Many of ancient bronze mirrors were made of leaded high tin bronze. Contents of major three elements, which are copper, tin and lead, greatly affect properties such as hardness, ductility, color and castability. It is therefore important to know the contents of those elements. However, X-ray fluorescence analysis is not practicable due to existence of thick corroded layer on excavated mirrors, while the ratio of components of copper, tin, and lead could be determined if the area ratio of each of alpha phase, eutectoid phase and lead phase which compose metallic structure is calculated. In this study, we tried to develop a new method of qualitative analysis of ancient high tin bronze mirrors.
