Part.
(Founding.) A certain portion of a mold or flask; as the top part or drag, the bottom part or cope, the middle part contained in the middle portion of a three-part flask, etc. (See flask.) The false part is a flask rammed up, generally a top part turned over, stricken off, and a cavity scooped in it to receive temporarily the bulge of a pattern while sand is being rammed upon the upper surface. The whole is then turned over, the false part destroyed, and the parting made.
