Mainly composed of tin and copper, bronze alloys are joined together and heated. Once molten, the metal is poured into the cavity of the fire-hardened clay. The metal cools and the sculptor strikes the clay from the metal.

The ancient technique known as lost wax casting in the bronze casting process has endured throughout the centuries from ancient cultures through their different cultures and religions. There are a multitude of representations made as bronze castings, for example: Chinese bronzes often depict ceremonial images, Indian and Egyptian castings frequently depict deities.
Many elements of lost wax casting used in the bronze casting process have been refined, however, bronze casting is still essential in many applications and applications today.

The most modern sculptors who want their pieces in bronze depend on a bronze foundry. Artisans skilled in applying the lost wax casting technique to wood, stone, clay, plaster and virtually any other form of sculpture to transform the artist’s vision into bronze.
The metamorphosis of the bronze sculpture from the original bronze support begins with a rubber mold. The original sculpture must remain fixed during the mold making process. To achieve this, half of the sculpture is set in a soft plasticine clay base and the other exposed half is painted evenly with a clear viscous rubber.

When the painted medium with rubber dries, a protective and reinforced plaster mold is built around the flexible rubber. The bronze sculpture is next, turned over, and the process is repeated. When the second side is complete, the mold is opened and the original is removed from the inside. The rubber is bonded to the other half, which makes an accurate negative image of the rubber sculpture. The mold is often made in several sections to facilitate proper flow and even during actual bronze casting.
