云南昆明石寨山出土汉代青铜器的初步分析

A preliminary analysis of Han Dynasty bronzes unearthed at Shizhaishan,Kunming, Yunnan Province

云南昆明的石寨山墓葬是汉代滇池区域的土著文化,为了了解该地汉代铜器的制作工艺水平,本研究通过金相显微镜观察、扫描电镜及能谱分析的现代分析手段来对M3、M5、M6、M7、M10、M12这6个墓葬群的31件青铜器展开探讨。结果显示在31件铜器样品中,有30件为铜锡合金,1件为红铜,所有器物均为铸造,其中有1件铜戈的刃部经历过热锻加工。这一分析结果丰富了石寨山文化的铜器研究,为器物的保护修复提供科学依据,同时也为云南汉代时期的铜器考古学以及金属技术史补充部分资料。

Shizhaishan tombs are indigenous to the Dianchi region of the Han Dynasties.In order to understand the production process of Han Dynasty copper artifacts in Kunming,Yunnan Province,we used metallographic microscopy,scanning electron microscopy-energy dispersive spectrometry to study 31 bronzes from six tomb groups:M3,M5,M6,M7,M10 and M12.The results show that 30 objects are copper-tin alloys and that one is red copper,and all of them were cast,with only the blade of a copper Ge undergoing hot forging processing.The analysis results enrich the study of copper artifacts of the Shizhaishan culture,provide a scientific basis for the conservation and restoration of artifacts,and also supplement some information for copper archaeology and metal technology history of Yunnan in the Han Dynasties.
