The mineral is hard compared to most of the objects it would be used to abrade. On the Mohs Scale of relative mineral hardness it's a seven with ten being the hardest.
It is not widely used as an abrasive because quartz has a high silica content. Silica, in its natural form, is a potential health hazard (silicosis) when ingested through the lungs. Therefore, it is not frequently used as an abrasive in abrasive blasting applications.

∙ 13y agoSeveral types of rock have been used to make sandpaper over time. Emery (a mineral called corundum), Garnet and Flint are three - there may be others. There is even a very fine paper or cloth abrasive called "Crocus cloth" made from Iron oxide. Today, though, almost all sandpapers are made from Aluminum oxides.
