SIO-2® Berlin Gray Stoneware High Fire Ceramic Clay Body, 27.6 lb

Grey 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. 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 a convenient 4 lb size to accommodate smaller projects, or to test if this is the right clay for you.
