摘要

The craft of bronze vessels from China’s Eastern Zhou period remains insufficiently understood, with prevailing assumptions that decorations were created with iron tools. This study re-examines these assumptions by applying a multi-analytical methodology, including three-dimensional digital microscopy, optical microscopy, and scanning electron microscopy with energy-dispersive X-ray spectroscopy, to analyze a rare engraved bronze yi vessel from the Fenshuiling cemetery, dated to the mid-Warring States period (c. 4th century BCE). The investigation identifies the vessel’s engraving tools, techniques, and sequence. Findings demonstrate the vessel consists of hot-forged, leaded tin bronze. Chasing is identified as the principal engraving technique, rather than scribing. The material’s estimated hardness supports the hypothesis that high-tin bronze tools were employed. Toolmark superposition analysis reveals a complex, multi-stage engraving process. This study provides the first science-based characterization of the engraving craft, demonstrating a systematic and scheduled approach to metal decoration that challenges previous technological interpretations.
