iron oxides
Corrosion's red residue
Iron oxides are chemical compounds of iron and oxygen, occurring naturally as rust and in minerals like hematite and magnetite.
They produce the red, yellow, brown, and black colors in soil, rocks, and rust.
Iron oxides serve as pigments in paints and cosmetics, and as the magnetic coating on traditional audio and video tapes.
