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.
Investment casting is an industrial process based on lost-wax casting, one of the oldest known metal-forming techniques. [1] The term "lost-wax casting" can also refer to modern investment casting processes. Investment casting has been used in various forms for the last 5,000 years.
Bulhomal's celestial globes were made both for decorative and instructive uses. The stars and constellations on these globes are labeled based on Arabic and Persian versions from Ptolemaic traditions.

The technique was exactly the same as for vinyl. A long-winded process, and the wax temperature was a major issue, but it was cheap and re-cyclable. The rats loved it... I'm sure you're right - as gelatine has been consigned to history, it might belong in an extended article on the history of lost-wax. It would be an unwarranted discursion in ...
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]
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.
