At its most basic level, casting bronze entails pouring a molten mixture of copper and tin into a mold and letting the mixture harden as it cools. In ancient China, the actual process was quite complex and involved ceramics technology in virtually every step. First, a model of the desired shape was created in clay and fired in a kiln; next, fresh clay was packed around this ceramic model, removed in multiple sections, and fired; and finally, the hardened section molds created in this process were reassembled around a ceramic core with space set between core and molds, and molten bronze was poured into this assemblage. The production of bronzes in China was inextricably linked to the region’s millennia-long ceramics tradition — in its use of kiln technology, its adaptation of ceramic vessels for bronze vessel shapes (such as the tripod ewer displayed here), and the creation of a casting method reliant on a potter’s skills.
