This article presents an analysis of the bronze artifacts and smelting remains unearthed from the Yanshi Shang City site,focusing on microstructure,composition,and inclusions.The results reveal that the majority of bronze wares were crafted through casting processes.However,the skilled artisans of the Yanshi Shang City site possessed proficiency in various cold and hot processing techniques,particularly demonstrating a well-developed forging process.Tools and weapons,on the other hand,were fashioned through casting or forging methods,with the selection of these methods for shaping each type of bronze artifact appearing somewhat arbitrary.A standardized processing approach for specific tool and weapon categories may not have been established.The high tin and low lead content in tools and weapons from the Yanshi Shang City site can be traced back to alloy technology from the Erlitou period,which was further refined and developed.Additionally,evidence suggests that the Yanshi Shang City site engaged in copper melting activities,possibly indicating local production.
