TOFFEE Caramel Stoneware Clay

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).

Firing range recommended for the clay to develop its best performance, both in terms of technical and safety characteristics, under conventional firing conditions. The colour samples may show temperatures outside the recommended range to provide a broader view, but these are pieces fired under controlled conditions. Cone equivalence according to Orton table for self-supporting cones, regular-SSB and 150ºC/hr heating rate.
