Marble is a popular choice for countertops for its non-foliated material made of metamorphic rock. It’s composed of carbonated crystals, and is commonly used as building material. A benefit of natural marble is its hard substance, and also because of its wide variety of colors. Any water spills on marbles should be cleaned with a damp cloth followed by a soft towel because of its delicacy. Marble can complement any room of the house with its neutral array of colors and relatively smooth surface.
