SIO-2 MARTE red sculpture 0-0.5mm 12.5kg

Red sculpture clay with 40 % fine grog 0-0.5 mm (up to 35 Mesh). Designed for artistic ceramics, it is ideal for sculpture and decorative murals. The high content of grog confers a beautiful textured surface and an excellent behaviour during drying and firing. Depending on the firing temperature, it develops a beautiful range of red tones that intensify with temperature and provide an ideal means of artistic expression. 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 60 ºC/hr heating rate.
