Sio-2 PRAI White Stoneware Clay
Sold in 27.5lb bags

White stoneware clay with 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. 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. Suitable for tableware (food-safe), according to ISO 6486. Available in extruded body (moist form).
