When calcium carbonate quickly precipitates out of hot springs, a stone called travertine is formed. This fibrous stone is usually found in cream, white, and tan colors. Throughout history, it has been used for the construction of buildings. Travertine has been used for all types of construction, from ancient bath complexes to famous monuments. For walls, facades, and flooring, is a very popular choice stone because of the natural beauty it adds to any space.
