Natural Emery is brownish-black or dark gray in color. It is the hardest mineral after diamond, making it the second hardest mineral with a mohs hardness value of 8. Crushed or naturally eroded emery (known as black sand) is used as an abrasive — for example, on an emery board, as a traction enhancer in asphalt and tarmac mixtures, or as used in mechanical engineering as Emery cloth.Emery is used on surfaces to make them more resistant. Emery grains can be used as hard aggregates for anti-skid and non-wear flooring. This type of flooring is most useful in areas like warehouses with heavy forklift traffic, workshops where oil is spilled and heavy objects fall now and then, hospital ramps, reception areas wtih heavy foot traffic, ship decks, and treads of staircases and so on.
