This paper analyzes the bronze artifacts unearthed from the Yejiashan tomb no.M126 using technological detection methods.The results indicate that out of the 10 analyzed artifacts,seven are made of lead-tin bronze alloy,including six vessels and one weapon,while three are tin bronzes,all of which are vessels.These bronze artifacts were produced using the piece-mold casting technique.Among them,the object no.M126:16 is from the Shang Dynasty.Other artifacts fall into categories A and C of common lead bronzes.Among the bronze artifacts with clan inscriptions,some used the same or similar ores as those found in the Zeng State bronze artifacts,while others used different ores,reflecting the circulation of bronze materials during the early to middle Western Zhou period,with some being circulated in the form of sets of artifacts.
