Zeolite is a natural aluminosilicate mineral found in many locations throughout the earth. Our green Zeolite is from deposits in the Lori province of Armenia. Zeolite minerals are often located with deposits of the famous green earth mineral, celadonite, which is an abundant clay-like alteration in zeolite-bearing basalts.

Origin and History

Zeolite is a microporous, aluminosilicate mineral commonly used as commercial adsorbents and catalysts. The term zeolite was originally coined in 1756 by Swedish mineralogist Axel Fredrik Cronstedt, who observed that rapidly heating the material, believed to have been stilbite, produced large amounts of steam from water that had been absorbed by the material. Based on this, he called the material zeolite, from the Greek ζέω (zéō), meaning "to boil" and λίθος (líthos), meaning "stone". The classic reference for the field has been Breck's book Zeolite Molecular Sieves: Structure, Chemistry, And Use.
Zeolites occur naturally but are also produced industrially on a large scale. As of December 2018, 245 unique zeolite frameworks have been identified, and over 40 naturally occurring zeolite frameworks are known. Every new zeolite structure that is obtained is examined by the International Zeolite Association Structure Commission and receives a three-letter designation.
Metamorphism, especially at low pressures, is very widespread on Earth. Metamorphism is the change of minerals in pre-existing rocks. The change occurs primarily due to heat, pressure, and the introduction of chemically active fluids. Formation of a variety of silicate minerals like celadonite, a mineral origin of green earth pigments, and particularly zeolites is frequently observed at low temperatures.Source
Our Zeolite is from deposits in the Teghout Cu-Mo deposit (Tekhut) in the Lori Province of Armenia, located near the Shamlugh river.

Based on the zeolite 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 Zeolite is 34. This means 34 grams or milliliters (approx.) of linseed oil is required to form a coherent paste for every 100 grams of pigment. Zeolite has a Mohs hardness of 4 to 5, which makes it somewhat abrasive. However, despite its hardness, this pigment is easy to grind into both waterborne and oil paint.Toxicity
Zeolite is not considered a hazardous substance, however, care should be exercised when handling the pigment to avoid inhaling or ingesting the powder.
