A brownish-black iron ore. Black iron oxide is used in the manufacture of steel, glass and enamels. It has coarse particles that are strongly magnetic. Black iron oxide wets easily but it covers poorly and is unsuited for most use in paints. However, it is used to tint primers gray because it is inert and inexpensive.
