Metamorphic rocks formed in the process of transformation of carbonate rocks (limestone, dolomite), consisting mainly of calcite grains. Deep in the Earths crust high temperature and pressure transforms the rock, creating the new forms. These transformed rocks are called metamorphic rocks, marbles belong to them. Formed when the crust material is compressed and folded under the pressure of the mountains, or are under the influence of molten hot lava. Rocks after such processes are becoming harder. Depending on the type of organic additives, marble can take different colors: white, gray, pink, greenish, black, the browns, yellows, shades of red, black. It is a valuable sculpture material widely used since antiquity. Marble in its structure has the characteristic swirls, veins resulting from natural minerals of primary pollutants, formed from layers of limestone. They create unique designs and themes, giving individual character. Marble can be sanded, sawn, polished. Under the action of acidic water tarnishes and decomposes. Marble is a popular building material for centuries. Today is used in the construction industry as a material for interior flooring, wall coverings, counter tops, stair treads and window sills. Works well in areas with medium traffic, and less exposed to the weather, is applied mainly inside buildings.
