Travertine — a calcareous tufa, the polycrystalline haemo gene rock formed by calcium carbonate minerals (generally aragonite with a smaller share of calcite).
In the first century B.C. travertine was known under the name of lapis tiburtinus (a stone from Tibur). It is formed as a result of sedimentation of a carbonate of calcium of water of carbonic sources. Also it is allocated from underground waters in caves, forming stalactites and stalagmites.
It is widely used as a construction and facing stone (as well for finishing of internal rooms). Besides it is used in agriculture for lime application of the soil.
Travertine comes to us from a bottom of warm thermal sources. With the blank time and cavities it decorates facades of buildings. The travertine polished and processed by special fillers plays all shades of beige. Any products from travertine - window sills, table-tops, fireplaces, - become part of an interior, testify to refined taste of their owner.
