Abstract
Hot molten wax is injected under pressure into a cold mould, and when the outer layers of wax have solidified but before the wax at the centre has solidified the pressure is released and air under pressure is then injected into the mould, the air pressure being maintained until the whole of the wax has attained an appreciable degree of rigidity. The air may blow right through the mould, the outlet for the air being smaller than the inlet, the outlet being kept clear by pricking with a pin. The air is blown into the mould through the same inlet as that used for the wax.
