Now comes the actual bronze casting! The ceramic mold is heated in a kiln so that the sudden heat increase from the
molten bronze won't shatter the ceramic.
Bronze ingots or scraps are melted in a stone crucible and poured into the mold.
After the bronze cools, the ceramic mold is broken away from the bronze casting, leaving the third and last "positive" version of the
sculpture. Since the sprues have also been filled with bronze, they are still part of the sculpture at this point.
