Lost-wax casting

Definition

Lost-wax casting is a metal casting process that involves creating a model in wax, which is then coated in a ceramic shell. The shell is heated to remove the wax, leaving a cavity into which molten metal is poured. This technique was crucial in producing intricate bronze objects, particularly during the Shang and Zhou dynasties, and showcases the advanced metallurgical skills of ancient Chinese artisans.
