ABSTRACT:
A method of making a ceramic shell mould for casting includes making a pattern having an internal cavity in two parts from a disposable material, glueing the two parts together to complete the hollow pattern, filling the internal cavity with a ceramic material, and simultaneously or subsequently forming a shell of a ceramic material around the filled pattern. The pattern can then be eliminated to obtain a casting mould with an inner core made in situ.
