ABSTRACT:
This invention includes a method, a casting pattern, and an apparatus directed to gasifying residue during metal casting. The method for metal casting includes using a casting pattern that includes an additive that can react with a residue formed as the casting pattern degrades during casting. The casting pattern includes an additive that can react with a residue formed as a result of degradation of the casting pattern during casting. The metal casting apparatus includes a casting pattern having an additive that can react with a residue formed as the casting pattern degrades during casting, and a casting medium in which the casting pattern is at least partially immersed.
