Color & Veining of Travertine Cleaning & Protection of Travertine
Travertine is a massive form of calcium carbonate, usually layered, formed by deposition from spring waters or especially hot springs. Typically, it is banded and beautifully colored due to the presence of iron compounds and other organic impurities. Travertine is a variety of limestone that has a light color and takes a good polish; it is often used for walls and interior decorations in public buildings. Various names for this material do exist; calc-sinter and calcareous tufa and (when used for decorative purposes) as onyx marble, Mexican onyx, and Egyptian or Oriental alabaster.
