Illustration of stepwise bronze casting by the lost-wax method. 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.
In contrast to most foundries that have switched over to ceramic shell casting, Modern Art utilizes the lost-wax casting method for producing its large-scale work. [3] Workers first create a wax copy of the artist's original model and then apply a plastic coating to it. The mold is then fired in a kiln, which causes the wax to melt away. Molten ...

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.
To create their gold pieces, the Muisca used a method called lost-wax casting. [1] The manufacturing process itself was likely part of the ritual associated with these tunjos. [39] The process began when the Muisca craftsperson created a wax model in the desired shape of the object, using beeswax harvested from the region. [40]
The wax model is then coated with clay to form the mould. The first coat of clay is usually carefully brushed to prevent trapping of air bubbles; subsequent coats may be rougher. Then, the clay is fired and the wax melts (thus "lost wax"). Molten metal is then poured into the clay mould to replace the burnt wax model.
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 ...
In 2006, Milne created "Knitted Glass", incorporating the techniques of knitting, lost-wax casting, mold-making, and kiln-casting.As Milne describes in, "Knitting wasn't yet cool...": [9] The process involves (A) knitting the original art piece using wax strands, (B) surrounding the wax with a heat-tolerant refractory material, (C ) then removing the wax by melting it out, thus creating a mold ...
