Stoneglass® sheets are more resistant to acids and alkalis than marble, granite and quartz. Being an inorganic material with high chemical stability, the surface of the product does not suffer damage such as colour fading, loss of shine and solidity. It is non-absorbent and easy to clean. The material is manufactured by a process which achieves crystallisation without the use of resins or solvents. The product does not contain any components or substances harmful to health. Stoneglass® is completely recyclable. Its use means having health and the environment at heart. Stoneglass® is harder and stronger than natural stone, and succeeds in combining strength and lightness, as demanded by the most advanced construction principles.
