Iron Oxide Pigments - Dept of Mines Minerals and Energy. Natural iron-oxide pigments have been used for centuries as coloring agents. Iron-oxide pigments are valued because they are nontoxic, weather resistant and they do not bleed or fade. The pigments are extracted from a range of ores including hematite, goethite, limonite, siderite, and magnetite.

Limonite: an iron oxide used as pigment and iron ore

These pigments were prepared by grinding limonite to a fine powder. They are mixed with oil to produce a pigment of the desired consistency and mixed with one another, or other pigments, to produce an infinite number of other hues. Limonite has been used as a low-quality iron ore for thousands of years.
