A Review of the History of Research in Lost-Wax Casting in Bronze Age China Over the Past Century

Abstract

This study analyzes in detail the last century of scholarly study, in China and internationally, into China's Bronze Age lost-wax casting techniques. It finds that research beginning in the early twentieth century has differentiated five lost-wax casting research periods, linked to different research methods and new archaeological discoveries of bronzes and casting relics. The methods that can be identified with a particular research period are: complete lost-wax (before 1931); semi lost-wax (1931–1959); complete piece-mold (1960–1977); both casting technologies (1978–2018); hollowed lost-wax (after 2019). Research shows that piece-mold casting was the dominant casting technology in the territories of the Shang and Zhou dynasty (before 221 BC) kings, but craftspeople used lost-wax casting skillfully at the latest in the Qin dynasty (before 210 BC). Lost-wax artifacts influenced by other cultures are occasionally seen in the border areas of the Shang and Zhou kingdoms. Research on organic constituents in the clay cores of hollowed lost-wax artifacts may provide a definite answer to this question.
