A method of casting including coating at least a portion of a mold with a non-porous coating, placing the mold in a chamber capable of inducing pressure, and applying pressure to the chamber to press material into a cavity in the mold. Another method of casting including coating at least a portion of a mold with a non-porous coating, placing a first fill tube in a material, applying a vacuum to a second fill tube to establish a vacuum within the non-porous coating, and allowing atmospheric pressure to inject the material into the mold without placing the mold in a chamber capable of inducing pressure.
