Composed of recrystalized minerals, marble is a metamorphic rock, formed under great geologic pressure. Marble is made of the same minerals as limestone, but has simply undergone greater pressure. This helps explain why marble is more expensive than limestone.
Marble comes in a diverse range of styles and colors. Polished marble tile is often used for flooring or bathroom finishes. This style has a distinct shine. The color of marble is determined by the region it comes from. Colors range from whites and grays to pinks, green and yellows.
Tumbled marble is more porous than polished marble. Often described as having a sponge-like consistency, tumbled marble is popular for tiled floors. Unlike polished marble, the colorful veins often associated with marble are absent in tumbled marble. This type of marble is often used to tile fireplace surrounds and also is used for bar tops and vanity tables. With a slightly rougher texture, tumbled marble is a more rustic alternative to polished marble.
Marble can stain and this should be taken into consideration when building with it. Treat marble like you would wood. Wipe up spills immediately and use coasters with drinks. Wash marble surfaces with hot water regularly and with a mild detergent once a year. Like all stone, it is subject to weathering. Ask your supplier about how to best care for your marble as different climates and weather affect marble in different ways.
