White earthenware clay specially formulated 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 earthenware bodies. Its coefficients of thermal expansion are ideal for standard pottery glazes, in both single and twice firing processes. Available in extruded body (moist form) in a wide range of water content depending on the shaping application: wheel-throwing, modelling and shaping processes (extruding and pressing).
