    By refractoriness, the mold does not break in very high temperatures as the molding process can be done with the help of high temperatures. If this property of the sand becomes poor then the surface of the molding sand will not be so smooth after burning that. This property depends on quartz content, SiO2 and the size and shape of the grain
