13 May Travertine
Travertine is a sedimentary rock formed in hot springs and is sometimes referred to as travertine marble or travertine limestone. Travertine is similar to limestone in mineral composition (Calcium Carbonate), but is uniquely characterized by natural cavities in its surface and the various patterns available. Travertine is noted for its low hardness and soft texture, making it easy to process and transport.
Travertine can be cut in a ‘vein cut’ to expose the linear patterns of the natural bedding planes. It can also be cut in a ‘cross cut’, which exposes a more random and subtle flowery pattern. Available in four major finishes; polished, honed, brushed and tumbled, travertine is supplied in textures ranging from being marble-like smooth to being rough as raw granite.
The small cavities that are inherent in all travertine are typically filled with grout to create a more durable surface. For some applications an unfilled travertine will create an interesting and unusual surface finish. Most commonly seen in tile sizes for indoor or outdoor flooring, travertine comes in a variety of earthy tones complete with a delicate look. Dimensional travertine is also available for use as vanity tops, fireplace surrounds, exterior cladding and a host of specialty items such as sinks and light switch plates. Travertine is also available in various building stone formats such as split-face ashlar or rubble veneer. For a truly natural look, travertine can be used to complete outdoor patios or garden walkways. To create a truly unique look, travertine can be mixed and matched with other stones to satisfy individual preferences. The most notable uses of travertine are the Colosseum in Rome, the Sacre-Coer Basilica in Paris and the Getty Center in Los Angeles.
