Core Mixture

any of the mixtures of quartz sand, binders, and catalysts used in making cores and other shapes for molds, for example, pouring basins and filtering gauze. Other refractory fillers are sometimes used in place of the quartz sand. Highly refractory additives, such as chromite, chromite-magnesite, zircon, and graphite, are introduced into the mixtures. The mixtures, which may be moist, dry, or liquid, are hardened in core ovens and in coreboxes, which may or may not be heated.
