Mexican Pottery Clay is a self-hardening, non-toxic and ready to use clay that comes in moist form. This clay achieves a rich red color that can be striking on its own with little or no decoration. After shaping by hand or thrown on a wheel, and with no need of oven firing or a kiln, Mexican Pottery Clay will harden to a durable form. It will shrink during drying and should never be modeled over a rigid form or armature. This clay is a great match with all methods of modeling including sculpting, coiling, pinching, slabwork, and wheel throwing. Made in the U.S.A.
