METHOD FOR IMPROVING STRENGTH OF GASIFIABLE PATTERNS ABSTRACT A core assembly is formed by molding a destructible plastic form in abutting relation to a rigid bonded core. The core assembly can be used for casting large or long and thin castings. The rigid bonded core reinforces the plastic form against flexural and torsional forces as well as forces within the plastic tending to change the dimensional configuration of the plastic form.
