The lost-wax technique is a metal casting method used in many Asian cultures. First, the sculptor shapes an image out of beeswax. Then layers of clay are applied to the wax model, from fine to coarse, creating a mold, usually in several parts. When the clay mold is heated, the clay hardens and the wax is drained out. The metalworker then pours molten metal into the empty space of the mold through the same channels the wax was poured out. When the metal has cooled and hardened, the clay mold is broken off, revealing the rough metal statue inside. This statue is often then polished, chiseled, combined with parts that were cast separately, gilded, inlaid with precious substances, and painted.
