Travertine

Travertine is a calcareous stone. It is a kind of limestone that forms from a chemically unique sedimentary stone, creating many small holes in the body of the stone, allowing larger crystalline structures to grow. These holes are often filled in the processing of the slabs with cement or epoxy, giving travertine its unique look. Travertine, like marble and other limestones, is best used for indoor applications, away from the thermal shock caused by abrupt and large changes in temperature.
