Bronze is an alloy of red copper andtin, which is widely used for fabricating sculptures. One question we’re often asked by clients enquiring about custom sculpture is what the main differences between cold cast and hot cast bronze sculptures. As to the cost and charge, the hot cast has significant price step-up as a perfectly reasonable concern. So for these practical considerations, it’s important to understand the differences between hot and cold cast bronze sculptures and the inherent physical properties of each option.

It is hard to see any difference seeing photographs of our sculptures, and the differences seem very subtle. The answer rests in the processes  to create each individual artpiece and. It’s worth noting that the initial stage of each process is essentially the same. Our experienced artisans create clay models with the help of wire skeleton armatures to establish the sculpture’s intricate 3D form for further fabrication.

When that metal sculptures is shaped exactly how we want it, when every detail of the character is just right, we make a rubber mold into which we pour two different types of casting: either hot cast or cold cast. A hot cast bronze sculpture is intentioned to be built last for generations by using ancient techniques survived for thousands of years, it’s an investment Bronze Statue will last generations.

Forging copper sculpture mainly relies on casting, and shapes the sculpture by extrusion under the action of high temperature. Cold cast is a forging process of metal materials at room temperature. Hot cast is the forging process when the metal material is heated above the recrystallization temperature.
