Limestone is sedimentary rock formed by cementing together of naturally accumulated rock fragments and organic sediments via a chemical process in shallow prehistoric marine environments. Limestone�s granular composition consists primarily of calcite. Limestone varies in degrees of hardness; the densest stones can be polished to a very high gloss finish. The most common colors are beige, gray, white yellow and brown. As with marble, acid and acidy foods will etch the surface of limestone. Proper care and maintenance requires the use of only neutral soaps and detergents. Limestone is also a porous stone and requires preventive scaling with silicone based impregnators. Limestone is quite durable, with proper installation and maintenance some types can perform extremely well, even in high traffic areas.
