Pigment type
Inorganic, Natural

Red Barite is a natural mineral composed mostly of barite with various amounts of hematite, quartz, and clay. The mineral is extracted from deposits in the vicinity of Akhtala, a town and municipal community in the Lori Province of Armenia, located along the Shamlugh river, on the slopes of Lalvar mountain. The colorant in Red Barite is hematite or red iron oxide, which is one of the most stable pigments known to humans. The iron oxide content of Red Barite classifies it as ocher, except that instead of large amounts of calcite, quartz, or clay, typical of ocher, our Red Barite contains barite or barium sulfate.

Origin and History

Barite, baryte, or barytes (UK spelling) is a mineral consisting of barium sulfate (BaSO4). Barite is generally white or colorless and is the main source of the element barium. Barite was named in 1800 by Dietrich Ludwig Gustav Karsten from the Greek βάρυζ, heavy, due to its unusual heaviness for a non-metallic mineral.

Barite occurs in many depositional environments and is deposited through many processes including biogenic, hydrothermal, and evaporation, among others. Barite commonly occurs in lead-zinc veins in limestones, in hot spring deposits, and with hematite ore, as is the case with our Red Barite. It is often associated with the minerals anglesite and celestine.

Barite has been found at locations throughout the world and on every continent, including Australia, Brazil, Nigeria, Canada, Chile, China, India, Pakistan, Germany, to name only a few countries.

Note: Although frequently spelled barite in the U.S. and some other places, the official International Mineralogical Association (IMA) spelling is baryte.


Our Red Barite is from deposits in the vicinity of Akhtala, a town and municipal community in the Lori Province of Armenia, located along the Shamlugh river, on the slopes of Lalvar mountain.

Permanence and Compatibility

Based on the colorant, iron oxide, and barite mineral, this pigment has broad compatibility and permanence with all media. Iron oxide is very lightfast and stable outdoors and has excellent weatherfastness.

Oil Absorption and Grinding

The oil absorption value for Red Barite is 24. This means 24 grams or milliliters (approx.) of linseed oil is required to form a coherent paste for every 100 grams of pigment. Barite has a Mohs hardness of 3, making it less abrasive than marble. This pigment is easy to grind into both waterborne and oil paint.


Red Barite is not considered a hazardous substance, however, care should be exercised when handling the pigment to avoid inhaling or ingesting the powder.
