Marble is mainly composed of calcite, limestone, serpentine and dolomite. Its main component is mainly calcium carbonate, accounting for more than 50%. Because marble generally contains impurities, and calcium carbonate is affected by carbon dioxide, carbides, and water vapor in the atmosphere, it is also easily weathered and eroded, and the surface quickly loses its luster. Marble is generally soft, which is relative to granite.
