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 history of lost-wax casting dates back thousands of years. [24] Its earliest use was for idols, ornaments and jewellery, using natural beeswax for patterns, clay for the moulds and manually operated bellows for stoking furnaces.
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]
Roman Bronze Works, now operated as Roman Bronze Studios, is a bronze foundry in New York City.Established in 1897 by Riccardo Bertelli, it was the first American foundry to specialize in the lost-wax casting method, [1] and was the country's pre-eminent art foundry during the American Renaissance (ca. 1876–1917).
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]
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 ...
Skoogfors often used the lost-wax casting process. [3] He was introduced to lost-wax casting in metal by Ruth Radakovich and Svetozar Radakovich. [1] This process enabled Skoogfors to create more sculptural forms. He also used fusing, reticulation and chasing techniques in his work.
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 ...
