Abstract: Sanxingdui site is located on the alluvial plain of Yazi River with the quartz-rich clay, which influenced deeply the pottery making techniques of Sanxingdui people. This study was aimed to focus on the chemical composition and inclusions of the pottery samples collected from the first to the fourth period of Sanxingdui site. It was revealed that quartz was present as the main inclusion that directly determined the content of Si. Meanwhile, a significant change in chemical composition and inclusion happened in the potteries in the third period, with abundant Al-rich mineral particles and significant reduction in the content of quartz. As well known, brilliant bronze smelting and founding profession were flourished in the third period of Sanxingdui site, during which earthen smelting furnace was strongly demanded, thus having an impact on the production of sand-containing potteries at that time.
Key words: Sanxingdui site; pottery; Qingguanshan; inclusion
