ABSTRACT:
A method of forming an integral casting core includes adding a disposable insert to a metal core die and disposing a slurry into the metal core die. The slurry includes ceramic particles. The method further includes firing the slurry to form a integral casting core and removing the disposable insert from the integral casting core.
