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.
The fragile wax patterns must withstand forces encountered during the mould making. Much of the wax used in investment casting can be reclaimed and reused. [2] Lost-foam casting is a modern form of investment casting that eliminates certain steps in the process.
The lost-wax casting technique Robinson developed is a modified version of the bronze casting technique. It involves creating a plaster mould which is filled with molten wax. The mould is then removed (and can be reused) and the wax is encased in a heat-resistant covering and placed in the kiln.
Dancing Girl is a prehistoric bronze sculpture made in lost-wax casting about c. 2300 –1751 BC in the Indus Valley civilisation city of Mohenjo-daro (in modern-day Pakistan), [1] which was one of the earliest cities. The statue is 10.5 centimetres (4.1 in) tall, and depicts a nude young woman or girl with stylized ornaments, standing in a ...

Dhokra (also spelt Dokra) is non–ferrous metal casting using the lost-wax casting technique. This sort of metal casting has been used in India for over 4,000 years and is still used. One of the earliest known lost wax artifacts is the dancing girl of Mohenjo-daro. [1]
The second method was hollow lost-wax casting, which was created by a direct process. Finally, the third was hollow lost-wax casting by an indirect process. The model is packed in clay, and then heated in what today would be similar to a kiln to remove the wax and harden the clay. Then, the mold is inverted and metal poured inside it to create ...
Lost-foam casting is a type of evaporative-pattern casting process that is similar to investment casting except foam is used for the pattern instead of wax. This process takes advantage of the low boiling point of foam to simplify the investment casting process by removing the need to melt the wax out of the mold.
