Marble has been valued for thousands of years for its rich palette of beautiful colors and appearance and is perfect, pretty much anywhere in the house. Marble stones consist of limestone that has undergone heat and pressure. A transformation process takes place when the weight of overlying material, pressure from crystal collisions and heat from the earth's core generate temperatures in excess of 1800ºF.Texture of marble depends on the form, size and uniformity of grains. The element components of marble determine the color of the stone. Generally calcite and dolomite marbles are of pure white color. Variations of whiteness of pure marbles are due to the mixture of foreign substances. Such impurities form streaks and clouds.
