Material Notes:

TI-21 is a very low carbon content clay specifically designed for plastic forming methods. It has excellent oxidation qualities particularly for dense volume stoneware or vitreous ceramic pieces. The excellent plasticity provides outstanding jigger, ram pressing or hand throwing qualities to the formulation. The Fe2O3 and TiO2 content produces a cream white fired color for enhancing a stoneware appearance to the formula.Information provided by Old Hickory Clay Company
