| Abstract: |
| The site of Tongshanling locates 50 meters diagonally opposite the office building of Tongshanling Farm, Jiangyong county, Hunan province, with a relic area of about 2 000 m2. The second national census of cultural relics designated it as a mining and metallurgical site from the Warring States Period to the Han Dynasty. In 2020, fieldwork was conducted at the site and metallurgical relics were collected. Energy dispersive X-ray fluorescence spectrometer EDX and scanning electron microscope energy dispersive spectrometer (SEM-EDS) were used to detect and analyze the matrix components and metal particles of seven slag samples obtained from the site. The preliminary research shows that the site uses the sintering-reduction smelting method, and the smelting product is crude lead. The slag is all reduced slag with proper melting point and good fluidity. Lead content in the slag is relatively stable, indicating that the smelting technology at that time has reached a certain level. |
