Claim Text:
1. A method of manufacturing a casting comprising: heating a ceramic mold comprising a gate inlet, the ceramic mold being formed by investment casting; melting a metallic composition; presenting the heated ceramic mold to a casting station such that the gate inlet is in fluid communication with the molten metallic composition; casting against gravity the molten metallic composition into the heated mold through the gate inlet; rotating the mold to position with the gate inlet in an upward direction while the metallic composition is at least partially molten within the mold; quenching the ceramic mold having the molten metallic composition in an aqueous polymer quench medium, at a desired quench rate; solidifying the molten metallic composition within the mold at a solidification rate that is controllable by the quench rate; and controlling the solidification rate by controlling the quench rate.
