| Abstract: |
| Energy Dispersive X-ray Fluorescence Spectrometer (ED-XRF) and Scanning Electron Microscope Energy Dispersive Spectrometer (SEM-EDS) were used to analysis matrix composition, metal particles and phases of metallurgical relics unearthed from rammed earth ruins on west side of west gate of small town of Linzi City Site of the Qi state. Preliminary research results show that type of slag is all reduced slag, which uses sulfur-containing copper-lead ore for pyrometallurgical smelting and is equipped with tin material. Liquid layered upper layer during smelting process is cast to obtain high-lead lead-tin bronze coin, and the lower layer is high-lead. The alloy can use condensate method to produce metallic lead and lead-tin bronze. This research initially reveals nature of metallurgical activities of the site to produce lead bronze through smelting activities and directly cast with tin material to obtain high-lead bronze coins, which provides for further excavation of metallurgical connotation of the site and reconstruction of the site’s casting process and production chain. The important clues are also very important for understanding development of ancient Chinese coinage metallurgical history. |
