The making of a Hot-Cast Bronze is a complex and time consuming process, and specific technical expertise is needed to accomplish the task of making a bronze. The most known and used process for making sculpture is called the "Lost Wax" Process:

A 1/4 inch hollow wax of the sculpture is made from the rubber mold capturing all the details . The wax is layered inside and outside with seven coats of a ceramic shell material; which harden around the hollow wax sculpture. The ceramic shell is then placed into an oven and the wax sculpture is melted out. This leaves a 1/4" space once occupied by the wax. Molten bronze is then poured into this space in the ceramic shell, and is set aside to cool and harden. The ceramic shell is broken off the bronze and the finishing process begins; cleaning and chaising the bronze sculpture. The finished bronze is then ready for patination. A torch is used to heat up the surface of the sculpture, chemicals deluted in water are brushed onto the heated surface creating a wide range of colors and patterns. This is just a brief explaination of the process and to really appreciate the process, one should visit your local sculpture foundry.

Cold-Cast or Bonded Bronze can also be collectable and allows a wider range of clients. It is also very durable, and larger sculptures (Tiger Stadium) can be created at a fraction of the cost if bronze is out of the question.
