Lost Wax Casting

Lost wax casting is the process of surrounding a wax sculpture with ceramic until it forms a shell. The wax is then melted out of the mold. It can then be used as a mold for creating metal versions of the wax mold. The final objects are removed by breaking the ceramic shell.

Lost wax casting has been around for a long time. There is evidence of the ancient Egyptians using it. It can be used to make a variety of things including sculptures, jewelry, and medical tools. It is possible to create hollow shapes, which can help reduce weight of the objects. Like many other processes, it uses a good deal of energy for heat but the ceramic molds can be recycled to be used again.
