Concrete gray color, unfired clay is the natural clay for modeling, which hardens independently in the air, does not require firing, achieving high strength, hardness and toughness. Its loamy nature gives it a very good plasticity for modeling and the natural fibers present allow it to dry without cracking, even with larger or massive objects. It allows modeling with very fine details. Can be modeled and turned on the potter's wheel. Hands and clothes can be easily cleaned with water. A damp cloth allows cleaning all remaining product residues from surfaces and furniture. After drying, the clay can be painted or varnish. It can also be polished, sanded or perforated. Can be waterproofed after complete drying (4-5 days) to make sealed "non-food" containers. Maintains its material properties in the original packaging for a period of at least 2 years.
