Crushed glass can be used as an abrasive for blasting paint and other materials from hard surfaces. Many large organizations including the U.S. Navy are approving the use of crushed glass as an abrasive. Crushed glass that is recycled is nontoxic and contains no free silica, making it safe for blasting projects. Crushed glass provides an abrasive that can be used as a substitute for silica sand. It has a hardness of 5.0 to 6.0 on the Mohs hardness scale, which means it is tough enough to remove most materials. The Mohs hardness scale is a scale used to determine the hardness of a material by scratching it with other materials. A diamond has a 10 hardness on the Mohs scale, while talc has a hardness of 1. Many abrasives that are used in blasting projects have heavy metals such as lead and arsenic; crushed glass has no toxic metals.
