| Research Abstract |
40 copper ware objects, including bangles, spoons, and bowls, which were excavated in Korea were subjected to chemical analysis and microstructure observation. Their chemical compositions turned out to be same as that of contemporary yugi, Korean high tin bronze ware. Contemporary yugi wares are generally made by casting, but most of the excavated objects were found to be made by forging cast alloy plate followed by annealing.
