Abstract

A shaker molding assembly. The assembly includes mold halves which are urged together as they are pushed into a holder. A measuring cup can be held against the mold halves to urge them into the holder. Ribs on the mold halves cooperate with a frusto-conic wall of the holder to urge the mold halves together. A mixture of water and a molding powder are shaken together in the assembly to form a smooth mixture. The molding powder includes an alkali metal alginate, calcium sulfate, tetrasodium pyrophosphate, and a filler. The mixture sets to form a jelly-like object which dries to form a rigid object of smaller size which is a substantially exact miniature of the jelly-like object.
