silica sand core making

silica sand used in the making of the core. As temperature rises, the silica goes through a rapid phase of expansion, causing cracks in the core or mold. This allows the molten metal to flow into these cracks, forming veins in the casting. Veining in the metal must be removed in the finishing room.
