Lost wax process is an antique method of casting bronze sculptures. From the model, a rubber mold is made and the cavity is filled with wax. By the heat the wax gets melted away leaving a hollow mold, hence the term ‘lost wax’ or ‘cire perdue’. Molten bronze is then poured into this hollow shell to create the sculpture. The lost wax process is considered the highest quality method of producing limited edition bronze sculpture. After the process is completed the sculpture is ready for patination.
