摘要

This paper utilizes microscopic observation, optical microscopic, SEM-EDS to analyze 9 bronze artifacts which were excavated from the tomb of Hou-taomuga Site, a Baijinbao culture in Dagan, Jilin Province. Combined with their unearthed information, it can be sure that the people had started to use bronze of copper-arsenic in this area during this period. The decorations of 8 bronze artifacts might be produced by the same mound, and some objects might be casted together. Their composition was stable, so these bronze might be made up of copper and arsenic antimony lead intergrowth ore smelting. Also, they might be arsenic containing antimony and lead ore collocation with copper ore smelting production.
