TravertineGenerally, Travertine is older than limestone but not as old as marble. Travertine is more porous than most other natural stones. Travertine is rich in calcium and is commonly confused with limestone. Yet, travertine rarely has seashells, a common characteristic of limestone. It is mostly formed through chemcial precipitation in cave-like and hot spring environments. Usually this stone is honed in finish (versus a polished marble) and is rougher in texture. Honed stones like Travertine are known for their inherent variations in color, surface texture, and finish. Its care:Depending on the type of travertine, care must be taken during cleaning. Thorough vacuuming and mopping with clean water and neutral pH soap inhibit dirt and soil build-up. Every few months, bleach can be used to keep this more textured stone with its characteristic voids and holes, and wider grout joints cleaner, and lighter and brighter. Depending upon wear, location, type, and care, it will need professional maintenance every 1 - 3 years.
