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.
Clay earth pigments (naturally formed iron oxides). 1  Raw Umber (PBr7): a natural clay pigment consisting of iron oxide, manganese oxide and aluminum oxide: Fe 2 O 3 + MnO 2 + nH 2 O + Si + AlO 3. 2  Raw Sienna (PBr7): a naturally occurring yellow-brown pigment from limonite clay.he following list includes commercially or artistically important inorganic pigments of natural and synthetic origin. The only dyes listed are derived directly from inorganic pigments.
