炉渣分析揭示古代炼铜技术

Slagery of copper smelting in antiquity

对古代炼铜工艺、熔炼过程及其炉渣进行了分类，建立了以铜和硫的赋存状态与相对含量（Cu／S）鉴别炉渣种类，进而结合其它遗迹遗物来揭示古代炼铜技术的研究方法。

A method has been built to identify the techniques of ancient copper smelting mainly by the analyses of slags. There were two styles of smeltings or slags in ancient copper pyrometallurgy. The existing forms and the relative contents of cop-per to sulfur (Cu/S) can be used to identify the styles of slags. The special contents in slag can be used to identify the forming of slag. The style of slag can tell which kind of technology was used in antiquity through the analyses of ore and metal.
