吉林大安后套木嘎遗址AⅣ区出土铜器的科学分析
|
摘要
对吉林大安后套木嘎遗址AⅣ区出土的74件铜器进行了科学分析。通过金相组织观察和扫描电镜能谱分析,表明当时的工匠已能够根据所需器物类型进行加工方式的调整,但铜器整体制作水平一般。器物的合金配比稳定,部分器物的型式相同,合金成分配比相似且出自于同一墓葬,推测为同批次铸造而成。该区域出土的铜器以铜锡合金和铜锡铅合金为主,兼有少量铜锡砷及铜锡砷铅的合金类型出现,推测含砷器物可能为含砷的共生矿冶炼而成或铜矿石搭配含砷的矿石一同冶炼而成。
Scientific analysis of 74 pieces of bronzes unearthed in the Phase AⅣof Houtaomuga Site,Da'an,Jilin Province were conducted.By means of metallographic observation and SEM-EDS,it is shown that the craftsmen at that time are able to adjust processing methods according to required types of utensils,but overall production level of the bronze ware is general.Alloy proportion of the object is stable,some samples are of the same type,and the alloy composition is similar and originates from the same tomb,which is supposed to be cast in the same batch.The copper wares unearthed in this area are mainly copper tin alloy and copper tin lead alloy,and the alloy types of both a small amount of copper tin arsenic and copper tin arsenic lead appear.It is inferred that the arsenic-bearing utensils may be smelted from arsenic ore or copper ore with arsenic ore.
