EMERY is a hard, rock-like material consisting largely of corundum (aluminum oxide). Iron oxides are often mixed in giving it that familiar dark brown to black color. Emery is an aggressive abrasive, but due to the mixture of materials, it typically has a hardness of approximately 6-8 on the Mohs scale.
