Self hardening artist clay for school, home, arts and crafts. Safe, multipurpose and economical. Dry-Hard clays are great for modeling, throwing, sculpting and thousands of crafting and hobby projects. 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 waterproof.
