High fire white body with 40% coarse grog 0-1.5 mm. Formulated for artistic ceramics, it is ideal for large sculptural works, murals and big Raku pieces. The high content of grog confers a beautiful rugged texture and an excellent behaviour during drying and firing. Its particular ivory colour after firing is much appreciated and provides an excellent ware for glazes and colouring oxides, which develop bright and intense tones. Available in extruded body (moist form).
