ABSTRACT:
A water soluble core comprising iggregate particles of an inert material and water soluble polyvinyl alcohol (PVA) binder results in an improved core composition having a longer shelf life and better release properties than other water soluble cores. The resultant core can be produced in less time and with less energy than other seater soluble cores, but is just as effectively remove d from the molded product upon exposure to water.
