Ball clay and kaolin clay are used in building materials like for the body formulations of wall and floor tile, as well as engobes and glazes for ceramic tile and brick. Ball clays impart green strength to the pressed tiles to reduce production losses due to handling cracks. Kaolin improves fired color of the tile body, reducing the need for expensive pigments for engobes.
Old Hickory Clay Company offers a wide range of solutions for ceramic tile bodies, but M-23 ball clay has become a very popular choice due to its low carbon content. UPF kaolin is an excellent choice for tile bodies to improve fired color, and engobes and glazes for tile and brick to reduce losses due to specking.
