Beauty and chemistry: the independent origins of synthetic lead white in east and west Eurasia

Abstract

Abstract Lead white is one of the most important pigments in human history, and its synthesis has promoted the development of art and cosmetics. The corrosion approach to synthesize lead white appeared in Greece during the fourth century BCE, and since then lead white has been produced on a large-scale and widely used in painting and cosmetics across Europe. However, when and how synthetic lead white appeared in east Eurasia and whether it was also involved with beauty remained unclear. Here, we investigate some white cosmetic residues from the Liangdaicun site during the eighth century BCE in northern China through FTIR, XRD, SEM-EDS, radioactive and stable carbon isotope analyses. The results show that these residues were the earliest synthesized lead white in the world to date, which was produced by the precipitation method in solution distinct from the corrosion method practiced in ancient Greece. Thus, the synthesis of lead white should have evolved independently in east and west Eurasia during the first millennium BCE. The mass production of synthetic lead white with lower cost promoted the widespread use of white makeup in China and the Mediterranean World, which triggered a cosmetic revolution and highlighted that the pursuit of beauty stimulated the development of chemistry in human history, especially the earliest wet chemistry practice in China.
