There are many steps in the production of a bronze sculpture; making the original model, making a rubber mold, casting and retouching wax patterns for each casting, investing the waxes in ceramic shell material, firing the shell mold and melting out the wax, pouring the molten bronze into the cavity, breaking off the ceramic shell, cutting the sprues and vents from the casting, welding, grinding, sanding, chasing each copy, applying the patinas, sealing the bronze and mounting it on a custom base.
