贵州可乐墓地出土铜器的技术研究

为研究古夜郎地区的青铜器铸造技术,本文对贵州可乐墓地2000年出土的33件铜器进行了金相观察和扫描电镜能谱分析,结果表明:战国早期至中期,铜锡合金的配比技术已经进入相对成熟阶段;战国晚期,可乐地区开始规范化、甚至批量化生产铜器;战国末期到西汉前期,铜锡铅合金的配比技术进入较成熟阶段;工匠先后掌握了锡青铜和铅锡青铜的制作性能,能够根据器物选择材质和加工方法;战国中晚期,可乐地区可能能够自行生产巴蜀、石寨山风格铜器,且与两地青铜技术水平相近。

Technical study of bronze objects excavated from the Kele Cemetery, Guizhou Province

In order to reveal technical characteristics of the bronzes in ancient Yelang area,Ibis paper presents the results of a preliminmy examination of 33 samples from Kele sile, which have been examined by Metallographie Microscopy and SEM-EDS. The results show thai Cu-Sn ratio teehnlogy had developed to a relatively mature stage in the early and middle Warring States Period. Kele began standardization and mass production in the late Wan＇ing Stales Period. Cu-Sn-Pb ratio technology entered Ihe mature slage from the end of the Warring Slates Period to the early stage of the Western ttan Dynasty. The workers had mastered production performance of Cu-Sn anti Cu-Sn-Pb alloy, selected material and production method according to bronze category. Kele produced Basha, Shizhaishan Style bronzes, which was at the same level with the other two areas.
