SIO-2® PF - Red Earthenware Clay, Low Fire
27.6 lb (12.5 kg)
PF is a traditional red earthenware clay body, suitable for wheel-throwing, shaping, and modeling. It is a high quality and polyvalent clay, very popular for its fineness and excellent plasticity.
Its coefficients of thermal expansion are ideal for standard pottery glazes, in both single and twice firing processes. Incredible results in reducing atmosphere can be obtained (metallic reflection technique).
It is available in extruded body (moist form), in a 27.6 lb. package.
