Marble is a kind of limestone that has undergone a proces which has made the structure of the rock more solid, making it able to withstand a high polish. It is generally formed when limestone is faced with extremes of pressure or temperature that cause it to undergo a process known as metamorphism. When this occurs the structure of the limestone becomes crystal in nature, taking the shape of calcite or dolomite. These two substances are the main materials in marble. The result is a stronger, highly publishable stone, with unique colored characteristics. These colors are often copied in book binding in a technique known as marbling. The different colors that marble can have occur when impurities get caught in the structure of the marble during formation. These impurities such as carbon, or iron, or oxides, cause streaks to appear in the surface of the stone. The number of impurities possible and the nature of their form, means that each piece of marble is one of a kind. The ancient Greeks and Romans both used marble expansively. The Greeks built many of their famous architectural masterpieces using Pentelic marble, and they carved many of the most famous statues in history from other Greek marbles. When the Roman Empire rose it conquered the Greek quarries, as well as many others. Marble is often heavily associated with the Hellenic and roman classical age of history. Today marble is used in stone home furnishings, floors, counters, clocks, hot plates, tables, pillars, structural resurfacing, even bathroom applications. It can be found in millions of places in millions of applications around the world. Its style and versatility make it one of the ideal choices for building materials and structural supply.
