Mexo White Self Hardening
Self hardening artist clay for school, home, arts and crafts. Safe, multi-purpose and economical. Just like other high quality Laguna stoneware clays, Dry-Hard clays are great for modeling, throwing, sculpting and thousands of crafting and hobby projects. The cure for shrinking school budgets, Dry-Hard’s self-hardening formula saves the hassle and expense of kiln firing, while producing a finished product which dries leather hard in 24 hours and rock hard within several days (actual drying time varies with temperature, humidity and thickness of clay). Decorate with acrylic paints. Must be sealed with a commercial water sealant to be waterproof.
