ABSTRACT:
A mixture of water and a molding powder are shaken together in an 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.
