Sio-2 Toffee Grey Stonware
Sold in 27.5lb bags

Caramel 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 a beautiful range of natural tones, from oatmeal beige to caramel brown, which create a warm base that is highly appreciated in ceramic decoration. Suitable for tableware (food-safe), according to ISO 6486. Available in extruded body (moist form).
