SIO-2 White Earthenware Clay 12.5kg bag

Special white earthenware body for throwing and modelling. It is a high quality and polyvalent clay, very popular for its finesse and plasticity. Its balanced calcium carbonate content confers higher
stability than traditional white earthenware bodies. Its coefficients of thermal expansion are ideal for standard glazes for pottery, in both once and twice firing processes. Available in extruded body(moist form) for throwing, shaping and modelling.
