Moulding, lost wax and investment

Wax is poured to form a hollow casting in the negative rubber mould. A system of runners and a hanging core supported by steel pins are added and the wax is invested with a ceramic shell. After dewaxing, molten metal is poured into the cavities previously occupied by the wax. The ceramic shell is broken and the runner system is removed by the skilled chaser who ensures the surface texture is restored to the artist's original detailed sculpture.
