Marble originates as limestone and then transforms into marble. It mainly consists of calcium carbonate which is much softer than granite. Marble has a hardness on the Mohs scale of 3 to 5. The metamorphic attributes of marble result in a more porous material. Some foods and liquids such as wine, lemons, vinegar and tomato sauce will absorb into the marble and can cause staining. Contact with hot pans can damage marble as well as cutting. Marble is suitable for low traffic areas and lacks the durability that granite has.
