Solid casting does not use a clay core but instead a solid piece of wax to create the mould; hollow casting is the more traditional method and uses the clay core. [1] The first task in the lost wax hollow casting process consists of developing a clay core which is roughly the shape of the final cast image.
The lost wax process originated in ancient Mesopotamia. The earliest known record of lost-wax casting is a clay tablet written in cuneiform in the ancient city of Sparta, Babylon, which specifically records how much wax is needed to cast a key. [6] The earliest-known castings in the global archaeological record were made in open stone molds. [7]
Lost-wax casting – also called investment casting, precision casting, or cire perdue (French: [siʁ pɛʁdy]; borrowed from French) [1] – is the process by which a duplicate sculpture (often a metal, such as silver, gold, brass, or bronze) is cast from an original sculpture. Intricate works can be achieved by this method.
He also formulated a wax pattern compound of excellent properties, developed an investment material, and invented an air-pressure casting machine. In the 1940s, World War II increased the demand for precision net shape manufacturing and specialized alloys that could not be shaped by traditional methods, or that required too much machining ...
When the cast sculpture has cooled or cured, the mold is again separated to release it and reassembled ready to cast the next copy. When molten bronze is used, it is more typical to use a lost wax or similar process so that the finished piece is hollow rather than solid.

A variation on the typical gravity casting process, called slush casting, produces hollow castings. Common casting metals are aluminum, magnesium, and copper alloys. Other materials include tin, zinc, and lead alloys and iron and steel are also cast in graphite molds. Permanent molds, while lasting more than one casting still have a limited ...
