Claim 8:
9. A method of solidifying a molten material, comprising:
providing a mold including a fluid permeable material, and providing nozzles arranged in voids in the fluid permeable material;
arranging the molten material in a cavity defined by the mold; and
delivering a cooling fluid to the fluid permeable material via the nozzles such that the cooling fluid permeates through the fluid permeable material, cools the molten material, and solidifies the molten material to a) form a solidified outer skin at a surface of the molten material, b) increase a thickness of the solidified outer skin, or c) both a) and b);
wherein the cooling fluid is delivered successively through the nozzles such that the molten material is solidified in a desired direction through the cavity; and
wherein the cooling fluid is delivered to the mold at a delivery pressure that is intentionally varied; and wherein the delivery pressure is varied as a function of the thickness of the solidified outer skin.
