Process for preparing olivine sand cores and molds

Material so prepared was then used as a binder for olivine sand. KOP 150 g was first mixed with the sand 1500 g, and water 75 g was added. The mixture was quickly packed into a Dietert Tensile Core Box which produces a "dog-bone" shaped core. After one hour the compressive strength was determined using a Dietert (454B) Mold Stength Tester.
