Red earthenware body with low coefficient of thermal expansion. Specially formulated for earthenware pieces those require some thermal shock resistance, for using into domestic ovens and direct flame (small pieces). Red-orange firing colour in oxidising atmosphere. High plasticity and dry bending strength. Suitable for both single and twice firing processes. Available in extruded body (moist form) in a wide range of water content depending on the shaping application: throwing, modelling and shaping processes (extruding and pressing).
