Caramel stoneware clay with 40% impalpable grog 0-0.2 mm (up to 80 Mesh).
Formulated for artistic ceramics, it is ideal for wheel 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).
