Abstract 1. A MOLD ASSEMBLY FOR FORMING A SLIP CAST BODY WITH A CAVITY OR CAVITIES ANS FORM A SLIP OF PARTICULATE INORGANIC MATERIAL IN VOLATILE VEHICLE, WHICH ASSEMBLY COMPRISES AN OPEN-TOP, VEHICLE-ABSORBENT MOLD, AT LEAST ONE SEGMENTALLY REMOVABLE, VEHICLE-OBSORBENT, COMPOSITE CORE MEANS IN SAID MOLD AND EXTENDING TO THE OPEN-TOP THEREOF WITH AN UPERMOST PORTION OF THE EXTERNAL SURFACE OF SAID CORE MEANS ADAPTED TO BE EXPOSED AT THE UPPER EXTERNAL SURFACE OF SAID BODY FORMED IS SAID MOLD, SUBSTANTIALLY THE REMAINING PORTION OF THE EXTERNAL SURFACE OF SAID CORE MEANS COOPERATING WITH SAID MOLD TO DEFINE A MOLD CAVITY AND CONTITUTING A CIVITY-FORMING SURFACE FOR SAID BODY, SAID CORE MEANS MADE OF AT LEAST ONE OF EACH OF FIRST AND SECOND SEGMENTS THAT ARE RIGIDLY UNITED TOGETHER, SAID FIRST SEGMENT OR SEGMENTS BEING ORGANIC POLYMER FOAM, SAID SECOND SEGMENT OR SEGMENTS BEING PLASTER CAST AND HARDENED IN CONTACT WITH SAID FOAM, PORTIONS OF SAID FIRST AND SECOND SEGMENTS FORMING SAID EXTERNAL SURFACE, INCLUDING SAID UPPERMOST PORTION AND SAID CAVITY-FORMING SURFACE, THE PART OF SAID CAVITY-FORMING SURFACE FORMED BY SAID SECOND SEGMENT OR SEGMENTS BEING GREATER IN AREA THAN THE REIAINING PART THEREOF FORMED BY SAID FIRST SEGMENT OR SEGMENTS, SAID SECOND SEGMENT OR SEGMENTS BEING MOVABLE, UPON REMOVAL OF SAID FOAM WHEN FORMED CAVITY-DEFINING SURFACE PORTIONS OF SAID BODY HAVE DEVELOPED SELFSUSTAINING SHAPE, INTO SPACE THERETOFORE OCCUPIED BY SAID FOAM AND AWAY FROM SAID SURFACE PORTIONS SO THAT SAID SECOND SEGMENT OR SEGMENTS ARE READILY REMOVABLE FROM SAID CAVITY OR CAVITY OR CAVITIES IN SAID FORMED BODY.
A MOLD ASSEMBLY FOR FORMING A SLIP CAST BODY WITH A CAVITY OR CAVITIES ANS FORM A SLIP OF PARTICULATE INORGANIC MATERIAL IN VOLATILE VEHICLE, WHICH ASSEMBLY COMPRISES AN OPEN-TOP, VEHICLE-ABSORBENT MOLD, AT LEAST ONE SEGMENTALLY REMOVABLE, VEHICLE-OBSORBENT, COMPOSITE CORE MEANS IN SAID MOLD AND EXTENDING TO THE OPEN-TOP THEREOF WITH AN UPERMOST PORTION OF THE EXTERNAL SURFACE OF SAID CORE MEANS ADAPTED TO BE EXPOSED AT THE UPPER EXTERNAL SURFACE OF SAID BODY FORMED IS SAID MOLD, SUBSTANTIALLY THE REMAINING PORTION OF THE EXTERNAL SURFACE OF SAID CORE MEANS COOPERATING WITH SAID MOLD TO DEFINE A MOLD CAVITY AND CONTITUTING A CIVITY-FORMING SURFACE FOR SAID BODY, SAID CORE MEANS MADE OF AT LEAST ONE OF EACH OF FIRST AND SECOND SEGMENTS THAT ARE RIGIDLY UNITED TOGETHER, SAID FIRST SEGMENT OR SEGMENTS BEING ORGANIC POLYMER FOAM, SAID SECOND SEGMENT OR SEGMENTS BEING PLASTER CAST AND HARDENED IN CONTACT WITH SAID FOAM, PORTIONS OF SAID FIRST AND SECOND SEGMENTS FORMING SAID EXTERNAL SURFACE, INCLUDING SAID UPPERMOST PORTION AND SAID CAVITY-FORMING SURFACE, THE PART OF SAID CAVITY-FORMING SURFACE FORMED BY SAID SECOND SEGMENT OR SEGMENTS BEING GREATER IN AREA THAN THE REIAINING PART THEREOF FORMED BY SAID FIRST SEGMENT OR SEGMENTS, SAID SECOND SEGMENT OR SEGMENTS BEING MOVABLE, UPON REMOVAL OF SAID FOAM WHEN FORMED CAVITY-DEFINING SURFACE PORTIONS OF SAID BODY HAVE DEVELOPED SELFSUSTAINING SHAPE, INTO SPACE THERETOFORE OCCUPIED BY SAID FOAM AND AWAY FROM SAID SURFACE PORTIONS SO THAT SAID SECOND SEGMENT OR SEGMENTS ARE READILY REMOVABLE FROM SAID CAVITY OR CAVITY OR CAVITIES IN SAID FORMED BODY.
