Study on high tin bronze fabrication techniques in East Asia via chemical composition analysis and microstructural observation of excavated copper wares in Korea

对出土于韩国的手镯、勺子、碗等40件铜器进行了化学分析和显微结构观察。事实证明，它们的化学成分与当代韩国高锡青铜器YUGI相同。现在的玉器一般是通过铸造制成的，但出土的大部分文物都是通过锻造合金板然后进行热处理制成的。

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.
