A method of making a ceramic ornament having short undercuts on a surface. A primary clay body is molded into a primary resin body by a silicone mold assembly. The primary resin body is then used to make upper and lower silicone mold assemblies. After slip is poured into the silicone mold assemblies, the plaster molding members will absorb moisture in the slip. Two clay body portions having a predetermined thickness are formed into shape. After removing the molding members and coating the connection line of the clay body portions with slip, the two silicone mold assemblies are combined. The two silicone mold assemblies will be formed into a complete figurative body upon the slip being dried. The figurative body is then fired at a high temperature so as to obtain a ceramic ornament having short undercuts and decorative threads on a surface.

[ What is claimed is:] [1.] A method of making a ceramic ornament having short undercuts on a surface thereof comprising the steps of:a) forming a primary clay body in the shape of at least a portion of the ornament having the short undercuts on a surface;b) molding silicone around the primary clay body;c) removing the primary clay body after the silicone has set to thereby form a silicone mold having the undercuts therein;d) molding a resin material in the silicone mold to form a primary resin body having the short undercuts on a surface;e) placing the primary resin body in a template such that a first portion of the surface of the primary resin body faces upwardly;f) coating the upwardly facing first portion of the surface of the primary resin body with a predetermined thickness of silicone to form a first silicone molding member;g) covering an exposed surface of the first silicone molding member with plaster slip and allowing the slip to harden to form a first molding member;h) inverting the first molding member such that a second portion of the surface of the primary resin body faces upwardly;i) removing the template from the first molding member;j) coating the upwardly facing second portion of the surface of the primary resin body with a predetermined thickness of silicone to form a second silicone molding member;k) covering an exposed surface of the second silicone molding member with plaster slip and allowing the slip to harden to form a second molding member;l) separating the first and second molding members and removing the primary resin body therefrom such that each molding member has a molding surface;m) coating the molding surface of each molding member with a predetermined thickness of sculpture clay;n) covering the sculpture clay with plaster slip in each molding member and allowing the slip to harden to form first and second upper molding members;o) removing the sculpture clay such that each molding member has a molding cavity bounded by the molding surface and the upper molding member;p) molding ceramic slip in the molding cavities and allowing the slip to harden to form portions of the ceramic ornament;q) removing the first and second upper molding members;r) coating a portion of at least one of the portions of the ceramic ornament with a slip layer;s) placing the first and second molding members together such that the portions of the ceramic ornament are in contact with each other and are affixed together when the slip layer hardens; and,t) removing the first and second molding members.
