50 years of bronze provenance studies: A perspective from China

Abstract

This review summarizes the current state of bronze provenance studies in China, highlighting both recent trends and challenges for scholars working with Chinese artefacts and beyond. The first section addresses the issues surrounding highly radiogenic lead (HRL) from the Shang period, arguably the most widely discussed topic in Chinese bronze provenance research. In addition to providing an overview of the current discourse, this section emphasizes two critical questions: the metal(s) with which HRL is associated, and the meaning of its isochron-like trend line. Clarifying these questions could fundamentally alter our understanding of HRL and the metal circulation systems of the Shang period. The second section focuses on the emerging pattern in the rapidly growing body of publications on lead isotope analysis of Chinese bronzes, particularly the synchronic alteration of lead isotope features across vast regions over two millennia. Additionally, this section reviews specific spatial-temporal units, which have generated significant research in recent years and may reveal distinct metal circulation systems. The following sections shift attention to the provenance of copper and tin, essential components in the production of bronze artefacts but often overlooked in provenance studies. Methodological challenges are discussed, with a particular emphasis on the widely used trace element analysis technique. Furthermore, increasing archaeological evidence from metallurgical workshops related to mining, smelting, and alloying practices of these metals holds potential to shed new light on these issues in the near future. Finally, the review offers a brief discussion on model-informed provenance investigations, reflecting a global trend in the field, which is expected to have a substantial impact on the study of Chinese materials in various ways.
