50lbs KYANITE GROG (100 MESH)A fine grog added to clay bodies primarily to reduce stress from dry shrinkage. In clays fired above 1100 C, it fires off white and begins to expand as it converts to mullite, effectively reducing the clays fired shrinkage. With a little clay and sodium silicate, excellent refractory mortars can be made with kyanite. For more information on kyanite, see the Digitalfire. com Reference Library of ceramic materials.
