The Sculpture/Raku Clay is formulated from finely ground white clays and medium grog to make an excellent and forgiving clay for Raku. The porosity is increased to reduce shrinkage, cracking, and warping. These pieces are shock-resistant when reduced with wide firing range of cone 05-5 and breakage is eliminated almost entirely. When reduction-fired and left unglazed, the clay will turn dark gray to black depending on the intensity of the firing.
