Nov 06, 2017 Theoretically the 400 mesh would go into the glaze melt better than the 270 mesh. But because it is slightly soluble, using the finer 400 mesh more surface area will also cause the glaze slurry to deflocculate quicker and the glaze will settle out and hard pan more easily. So theres a trade off. The mesh sizes in some materials are kept large to create specific effects, like granular illmenite or
