What is bronze casting?

Bronze is one of the oldest types of metal discovered by man. It is known to have existed around 3500 B.C. and first used by the Sumerians in Western Asia.

Liquid bronze is created by melting copper and tin and mixing them. Casting is the process wherein the molten bronze is poured into a mould created based on the model sculpture. The creation of the model and the negative mould is the first steps in the process of bronze sculpture production. The bronze is then let to cool down and harden for at least three days. Once it’s done, the shell or the negative mould is shattered to reveal the sculpture.
