A method of creating an article from investment casting includes forming a ceramic seed well, heating the ceramic seed well to form a hardened ceramic seed well, attaching a meltable pattern to the hardened ceramic seed well, coating the hardened ceramic seed well and the meltable pattern with hardenable ceramic material, heating the hardenable ceramic material to melt the meltable pattern, removing the meltable pattern from the hardenable ceramic material, firing the hardenable ceramic material to form a ceramic mold having a cavity, placing a seed within the hardened ceramic seed well, and pouring molten metal into the hardened ceramic seed well and the cavity. The cavity of the ceramic mold is in communication with the hardened ceramic seed well. |
