The final version was cast using ceramic shell technique, which has originally developed for precision castings. It is ideally suited to casting small-scale objects and was first used by artists in the 1950s. The wax is surrounded by a shell of ceramic particles bound together. As the shell is porous there is no need to construct vents to allow the gas given off during casting to escape.
