贵州银子坛墓地出土铜锡器的初步分析

为研究黔西地区铜器时代金属制作技术及水平,本文采用金相显微镜和扫描电镜,对贵州银子坛墓地出土13件铜器和2件锡器进行了金相观察和化学成分分析,发现中水银子坛墓地出土的战国到西汉时代的铜器,有红铜、锡青铜和铜锡铅合金多种材质,而锡器有纯锡器以及锡铅合金,合金配比已具有一定的水平。制作技术有铸造和锻造工艺,并能应用冷热加工技艺。本文对研究古夜郎地区金属器的制作技术有一定的价值。

A Preliminary Analysis of Bronze and Tinware Unearthed from the Yinzitan Tombs in Guizhou

This paper has examined the 15 samples of bronze and tinware artifacts unearthed from the Yinzitan Tombs in Guizhou by metallographic structure analyses and SEM-EDX.The SEM-EDX shows that the bronze artifacts contain copper, find-bronze and lead-bronze alloys,while the two Tinwareartifacts contain pure tin and tin-lead alloy. Moreover, the ratio of alloy hadreached a certain level of technique. The metallographic structure analysis shows that bronze wares are made bymeans of casting, forging and cold working. This study contributes to the understanding of ancient Yelang metal production technology.
