Abstract
A precision investment casting ceramic mold of the self-casting type is made as a unitary mold by providing separately a pattern for a wax charge-holding assembly and a pattern for a wax article casting assembly, each including an alignment portion. The two patterns are secured together at the alignment portions and are supported and located one with respect to the other by a plurality of supporting and locating members. The assembled patterns then are used in the conventional manner to make a ceramic casting mold.
