to overview
  • description material type
    Marble is a metamorphic carbonate rock and consists almost entirely of calcite and/or dolostone. It has been transformed by pressure and heat to a full-crystalline rock. Because of its crystalline structure, marble is slightly transparent when cut into thin slabs. Marble is mostly acid-sensitive and particularly suitable for many applications, indoors and partially outdoors.
