White earthenware clay that has been formulated specifically for wheel-throwing and modelling.

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 earthernware clays.

Its coefficients of thermal expansion are ideal for standard pottery glazes, in both single and double firing processes. Available in extruded body (moist-form), being suitable for wheel-throwing, shaping and modelling.
