The most industrially-important iron ores are chemically iron oxides.
Some iron oxides are widely used in ceramic applications, particularly in glazing. Many metal oxides provide the colors in glazes after being fired at high temperatures.
Iron oxides yield pigments (see iron oxide pigments). Natural iron oxides pigments are called ochres. Many classic paint colors, such as raw and burnt siennas and umbers, are iron-oxide pigments. These pigments have been used in art since the earliest prehistoric art known, the cave paintings at Lascaux and nearby sites. Iron oxide is typically used.
Iron pigments are also widely used in the cosmetic field. They are considered to be nontoxic, moisture resistant, and nonbleeding. Iron oxides graded safe for cosmetic use are produced synthetically in order to avoid the inclusion of ferrous or ferric oxides, and impurities normally found in naturally occurring iron oxides. Typically, the iron(II) oxide pigment is black, while the iron(III) oxide is red or rust-colored. (Iron compounds other than oxides can have other colors. )
