Join us for the in-person event on 'From Mine to Masterpiece: A Workshop-Centred Perspective on Great Shang Bronze Production' by Dr Siran Liu (University of Science and Technology Beijing). The Shang Dynasty (c. 1600–1046 BCE) is renowned for the scale, sophistication, and remarkable stylistic coherence of its bronze ritual vessels, which circulated across a vast region between the Yellow and Yangtze River valleys. This visual uniformity has long been read as evidence of a strongly centralised Shang court projecting its authority through standardised material culture. This argument is further strengthened by the widespread use of mysterious highly radiogenic lead across the whole geographic area influenced by the Shang culture. Yet despite decades of cataloguing and compositional characterisation of the finished artefacts, our understanding of the full production chain, from ore extraction and smelting to alloying, mould-making, and final casting, has remained surprisingly fragmentary. The past two decades have transformed this situation. Systematic excavation of copper-smelting sites in the middle Yangtze and of casting workshops at Anyang, Zhengzhou, and other Shang-period centres has yielded unprecedented quantities of slag, crucible fragments, mould debris, and unfinished bronzes. Integrated analyses combining FORS, lead isotopes, trace-element geochemistry, and micro-CT analysis of casting moulds now allow us to follow metal from mine to vessel and to reconstruct the technical choices made at each step. The picture that emerges departs sharply from the impression conveyed by the bronze artefacts themselves. Shang bronze production was a labour-intensive, technically conservative industry operating at relatively low efficiency, requiring enormous throughputs of ore, fuel, and human labour to sustain the ritual economy. At the scale of the workshop, centralised authority is strikingly invisible: mould recipes, casting sequences, core construction, alloying practices and source of metals varied not only between sites but within single workshop compounds. What we observe is better described as a cellular mode of organisation, in which multiple co-existing technological solutions were applied to the same production tasks, bound together by shared stylistic templates rather than by uniform technical protocols. Delivered in the spirit of Beno Rothenberg's pioneering vision for archaeometallurgy as a field rooted in landscapes of production rather than objects alone, this lecture offers a workshop-grounded reconsideration of Shang bronze production, and asks what a mine-to-masterpiece perspective can tell us about the social and political architecture of early Chinese states.
