Claystone is a fine, moist, plastic clay body that works like Plastilina, but air dries hard and durable, with minimal shrinking. Claystone is non-toxic, and is red, or granite gray in color. No baking, casting, or kiln is necessary. Claystone can be worked indefinitely while moist. Moisten it with a damp sponge during work, and cover it with plastic to retain moisture until the project is finished.
Note - Any combination of clay, plaster, sand, and molding material totaling 50 lbs or more does not qualify for our free shipping offer.
