Abstract
A slip casting mold consisting essentially of a gypsum mold, which contains a water-insoluble organic material, more particularly, a water-insoluble vegetable material such as cellulose, or which further contains glue in addition to the water-insoluble organic material. Since the strength of the casting mold is reduced markedly by heating, a cast article requiring a core (or master mold) having complex shape can be obtained extremely easily.
