White earthenware clay body especially formulated for wheel-throwing and modeling. It is a high quality and polyvalent clay, very popular for its fineness and plasticity. Its balanced calcium carbonate content confers higher stability than traditional white earthenware clays. Its coefficients of thermal expansion are ideal for standard pottery glazes, in both single and twice firing processes. Available in extruded body (moist form), being suitable for wheel-throwing, shaping and modeling.
