Produce wax patterns: Although called wax patterns, pattern materials may also include plastic and frozen mercury. [6] Wax patterns can be produced in one of two ways. In one process, the wax is poured into the mould and swished around until an even coating, usually about 3 mm (0.12 in) thick, covers the inner surface of the mould.
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.

Indicators developed for the efficient application of P&L charting or Drummond geometry include the assemblage of several P&L lines and levels into groups that represent future support and resistance "zones," which are further classified into "nearby" and "further-out" support and resistance areas.
Lost-foam casting (LFC) 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 polymer foams to simplify the investment casting process by removing the need to melt the wax out of the mold.
The approximately 10 inches (25 cm) high, 9 inches (23 cm) long, and 3.5 inches (9 cm) wide [33] beeswax sculpture is believed to be a maquette for a full size bronze sculpture. The model used to cast the sculpture sustained damage, resulting in the sculpture suffering the loss of the horse's front-left leg along with the rider's feet and hands.
Wax carving is the shaping of wax using tools usually associated with machining: rotary tools, saws, files and burins or gravers. Actual knives can be used and most certainly are, but the hardness of the material is such that they are not the ideal tool, generally.
