A very high-melting zero-plasticity material used in the refractories industry to make castables, brick, ramming and gunning mixes, mortars and potters grog. This material is fairly clean (speck free) and also answers a common need for stoneware clay bodies: An economical addition that will make the body more refractory but not add to its plasticity and produce drying problems.

It is fairly coarse and available in many particle sizes, the finest of which is 5-10% retained on a 70 mesh screen. Special sizes are available for custom orders.
