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.
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 this case the wax "pattern" is melted out from the mould cavity which is normally a rigid plaster like material rather than sand, so the wax "pattern" can only be used once. [5]

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.
These would have been created in wax around the ends of the wire. The wax is then coated, at least once, with a ceramic slurry and left to harden. The ceramic is then heated which allows the wax to leave and gold is poured into the cavity. This lost wax process allows the terminals to include a level of detail that was initially created on the ...
