As the sculpture cools the ceramic shell begins to pop away from the bronze. After the process of bronze casting, the sculpture gets covered with a layer of colourless wax to protect the patina. This will remove any ceramic shell that has stick to the bronze. Lost wax casting was first used by the ancient egyptians around 2500bc and the technique remains largely unchanged.
