It is a metamorphic rock which was formed in the result of the transformation of the carbonate rocks, mainly limestone and dolomite, after being subjected to high temperatures and pressure. Marble is easy to handle, and it can be polished, cut and carved. It is characterized by high hardness and resistance to abrasion (less than granite). Comparing to granite, it is characterized by a higher water absorption; therefore, it is not recommend it to be used in moist places. A contact with water or acids contained in the atmosphere and food products can cause stains which are difficult or even impossible to remove.
