SIO-2® PA - White Earthenware Clay, Low Fire

27.6 lb (12.5 kg)

PA is a white earthenware clay formulated for wheel-throwing and modeling. It is a high quality and polyvalent clay, very popular for its fineness and plasticity.

PA's 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.

PA is available in extruded body (moist form), in a 27.6 lb. package.

This product is being offered with $15 Shipping via USPS Priority Flat Rate Box for deliveries within the USA.
