 Travertine is a type of limestone that is formed by mineral deposits from natural springs. This sedimentary stone is created by the rapid precipitation of calcite. Other minerals mix with the calcite to create unique swirls and movements that give the travertine its distinctive character and color. Rublev Colours Orange Travertine contains small amounts of iron oxide that imparts an orange tint.

Origin and History

Travertine was used in stone masonry dating back to the First Dynasty of Egypt in 3200 BC. The name ‘travertine’ is just a corrupted version of the Latin name travertino, a derivation of the Latin lapis tiburtinus, which means ‘Tibur Stone.’ Travertine was first found in vast deposits by the ancient Romans in the city of Tibur, which is now known as Tivoli. Even today, Tivoli is one of the world’s leading travertine producers.

Travertine is a sedimentary rock formed by the precipitation of calcium carbonate minerals from freshwater, typically springs, rivers, and lakes—surface and ground waters. In the broadest sense, travertine includes deposits in both hot and cold springs, including the porous, spongy rock known as tufa and cave features known as speleothems (which include stalactites and stalagmites).

Calcite and aragonite, calcium carbonate minerals, are found in hot spring travertines. Aragonite precipitates when temperatures are hot, while calcite dominates when temperatures are cooler. When pure and fine, travertine is white, but it is often brown to yellow due to impurities, such as sulfur and ferric compounds, as found in our Orange Travertine.


Orange Travertine is from deposits in the Lori Province of Armenia.

Permanence and Compatibility

Based on the colorant iron oxide and the mineral calcite, 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 Orange Travertine 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. Travertine has a Mohs hardness of 4, which gives it the same abrasiveness as marble. This pigment is easy to grind into both waterborne and oil paint.


Travertine is not considered hazardous; however, care should be exercised when handling the pigment to avoid inhaling or ingesting the powder.
