BERLIN - SIO 2 Grey Stoneware

Sio 2 Grey Stoneware Clay has 40% impalpable grog 0-0.2 mm (up to 80 Mesh). Formulated for artistic ceramics, it is ideal for throwing and modelling smooth pieces with fine details. The high content of grog confers an excellent behaviour during drying and firing. Depending on the firing temperature, it develops an interesting range of greys, from cement to dark grey, which satisfies the most avant-garde trends in artistic ceramics. Suitable for tableware (food-safe), according to ISO 6486. Available in extruded body (moist form). Firing range: 1200-1300ºC / Cone 5-10; Biscuit temperature: 1000ºC / Cone 06; Water content: 19%; Plasticity (IP Atterberg): 16; Carbonate content (CaCO3): 0%; Drying shrinkage: 5.7%; Firing shrinkage 1300ºC: 6.4%; Porosity (water absorption) at 1300ºC: 0.1%; Dry bending strength: 2.9 N/mm2 Fired bending strength 1300ºC: 53.2 N/mm2; Thermal coefficient 1250ºC (25-500ºC): 60.1x10^-7ºC^-1.
