山东莱芜嬴城遗址炼铜渣初步研究

为了解山东地区早期冶金技术的发展情况,采用扫描电子显微镜分析等方法,对莱芜赢城冶炼遗址出土的3件炉渣进行了检测。结果表明其中2件为红铜还原渣,1件为砷铜熔炼渣。由此推测该遗址铜的还原可能存在两种工序,并且掌握了利用含砷矿物"点炼"铜液得到砷铜的技术。遗址所利用的铜可能来自于北江水铜矿,砷可能来自于鲁中山区,炉渣所属的时代应与遗址出土的商周青铜器年代相近。

A preliminary study on copper smelting slag unearthed from Ying City relics in Laiwu City, Shandong Province, China

In order to evaluate level of development of early metallurgical technology in Shandong Province, three slag samples unearthed from the Ying City relic site were analyzed by scanning electron microscopeenergydispersive spectrometry (SEMEDS). The results showed that two samples are copper smelting slags and that one is an arsenic copper alloy melting slag, indicating the co-existence of two copper smelting processes. The results also indicated that the making of arsenic copper alloys was achieved by purposely adding Ascontaining minerals during the smelting operation. The copper minerals used probably came from the Beijiangshui copper mine while the arsenic minerals used came from the central mountainous area in Shandong Province. These slags should be dated to a period similar to that of the bronze artifacts unearthed from this site and are attributed to the Shang and Zhou Dynasties.
