广西上林县馆藏东汉至南朝铜鼓科技分析研究

为配合保护修复的需要,利用金相显微镜、扫描电镜能谱仪对广西上林县馆藏6面东汉至南朝时期的冷水冲型铜鼓进行了科技分析。结果表明,这6面铜鼓均为铜锡铅三元合金组成,且为铸造成型,其工艺利用泥范法和失蜡法相结合的方法。由于冷水冲型铜鼓的合金成分和铸造工艺研究尚未见报道,因此,本研究分析数据为更深入研究冷水冲型铜鼓的科技内涵提供了重要参考。

Study on the science and technology of bronze drums of Guangxi Shanglin County in Eastern Han Dynasty to Southern Dynasties

In order to protect and repair bronze drums, optical microscopy and scanning electron microscopy with energy dispersive Xray (SEMEDX) were used to analyze six bronze drums from Shanglin County, Guangxi. These drums are dated to a period from the Eastern Han Dynasty to the Southern Dynasties. The studies suggested that 1) these six bronze drums are made from a CuSn Pb alloy; 2) they were made by casting molding; 3) the modeling methods include both the mud and lost wax methods. This is the first report on the alloy composition and casting method used for cold water washed bronze drums. Therefore, this paper provides information for future research on the technology of bronze drums of a similar type.
