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 behavior during drying and firing. Its particular ivory color after firing is much appreciated and provides an excellent ware for glazes and coloring oxides, which develop bright and intense tones. Suitable for tableware (food-safe), according to ISO 6486. Available in extruded body (moist form).

Comes in 27.5 lb. Bag
