Iron Oxide Pigments / Synthetic Iron Oxide. Synthetic Iron Oxides have become increasingly important due to their pure hue, consistent properties, and tinting strength. Single-component forms are mainly produced with red, yellow, orange and black colours. Their composition corresponds to that of minerals hematite, goethite, lepidocrocite, and magnetite. Brown pigments usually consist of mixtures of red and/or yellow and/or black iron oxides.
The mine, a trench some 130 feet long, was used by Native Americans to unearth red and yellow iron oxide pigments found in human archaeological sites in the Old World dating back at least 200,000 years. Iron oxides have been used extensively in the Americas from the Paleoindian period up to the ethnographic present.
