Emery is a very hard rock type used to make abrasive powder.It is black or dark gray in colour, less dense than translucent-brown corundum with a specific gravity of between 3.5 and 3.8. Because it can be a mixture of minerals, no definite Mohs hardness can be assigned: the hardness of corundum is 9 and that of some spinel-group minerals is near 8, but the hardness of others such as magnetite is near 6.
Crushed or naturally eroded emery (known as black sand) is used as an abrasive â for example, on an emery board, as a traction enhancer in asphalt and tarmac mixtures, or as used in mechanical engineering as emery cloth.
