The lead content is low or missing,ranging from 0 to 0.81% and averaging 0.323%.The four specimens are man-wrought,and three of them were quenched.Their alloying,forging and heat-treating techniques are all rather perfect,which reflects the advanced level of percussion instrument making in ancient China.展开更多
