Product Net Content UOM

White sculpture/raku clay with 40% fine grog 0-0.5 mm (up to 35 Mesh). Formulated for artistic ceramics, it is ideal for sculpture, murals and Raku pieces. The high content of grog confers a beautiful textured surface 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. It is also known as “Rafael” clay, and it is very popular because of its excellent behaviour for Raku. Available in extruded body (moist form). Firing range: 1240-1300ºC / Cone 6-10 Biscuit temperature: 1000ºC / Cone 06 Water content: 17% Plasticity (IP Atterberg): 16 Carbonate content (CaCO3): 0% Drying shrinkage: 5.4% Firing shrinkage 1300ºC: 4.6% Porosity (water absorption) at 1300ºC: 4.1% Dry bending strength: 2.4 N/mm2 Fired bending strength 1300ºC: 33.5 N/mm2 Thermal coefficient 1250ºC (25-500ºC): 59.8x10^-7ºC^-1 Storage: Protect ceramic clay bodies from direct sunlight, avoiding excessive temperature changes and protect from frost. Use: Technical details are available with information on the characteristics of each product and its use. It is recommended to test clay body prior to large scale use in order to verify suitability in both the ceramic process (shaping, drying, firing and decoration) and the final application that is expected to be obtained. Safety: All SIO-2® clay bodies are certified by the Art & Creative Materials Institute (ACMI) and conform to ASTM D-4236 safety guidelines.
