Suitable for use in all clays (throwing too), 35 mesh kyanite is a medium coarse grog added to clay bodies primarily to reduce dry shrinkage stress that leads to cracking. In clays fired above 1100º C, it fires off-white and begins to expand as it converts to mullite, effectively reducing the clay’s fired shrinkage.

With a little clay and sodium silicate, excellent refractory mortars can be made with kyanite.

Different Raw Materials ordered in full bag qty (20 kg to 100 lb) will be combined at checkout for a volume discount if applicable.
