Archaeologists in Shaanxi Province have unearthed a massive industrial wing of a Western Zhou Dynasty palace complex, specifically dedicated to the production of high-status bronze ritual vessels. The excavation has yielded over 200 intact piece-mold casting sets, many of which still contain residues of copper and tin alloys. Unlike general foundries, this facility focused exclusively on the creation of 'Ding' and 'Gui' vessels used in ancestral sacrifices, featuring intricate Taotie motifs and early bronze inscriptions.
The site includes a specialized chamber for wax-model carving and a series of temperature-controlled tempering pits, demonstrating a highly organized division of labor among imperial artisans. Researchers also discovered a cache of standardized jade measuring rods, suggesting that the proportions of these sacred vessels were strictly regulated by the central court. This find provides a rare glimpse into the political economy of the Western Zhou and the industrial scale of early Chinese ritual culture.
