Artstones is a Louisiana family business that makes beautiful keepsakes that become treasures! Artstones plaques are created by an age-old process know as sandcasting. A design is imprinted into the sand and a light cement-based medium is then poured into the imprint. Slight differences/variations appear in each piece adding that touch of uniqueness so that no two castings are exactly the same. Artstones are suitable for indoor or covered outdoor use. For outdoor use you may reduce the effects of the elements by coating with a cement weatherproofing product.
