Ball clays are very plastic and much finer-grained than kaolins. They are easily slaked in water when dry.The fine particle size also makes them impermeable to the passage of water for a good plasticity. Ball clays are used in ceramic bodies (porcelains, stoneware and earthenware, casting slips, pressing bodies) because of their plastic nature combined with high firing temperature. Ball clays have very high dry shrinkage combined with high green strength. Ball clays would be ideal ceramic materials. However, in practical terms, they are employed to achieve desired plasticity, but are minimized to reduce the detrimental effect on fired whiteness and drying properties.
