Marble is known as a non-foliated metamorphic rock, meaning it does not appear to have any layering, and has transformed from another material through heat, pressure and time. Marble ranges from between 1 and 4 on the Mohs scale, which determines material hardness, diamond has a rating of 10.
Marble has the ability to attain a very high polish, leaving the surface very smooth and with a lustrous shine. One of the features of marble is its slight translucent quality, allowing light to penetrate the surface of the stone and cause a slightly glowing reflection creating a very appealing effect. When marble is polished the natural colours are enhanced, making the stones qualities more noticeable.
Marble is a natural material and a relative of limestone which requires special care both because of its high value and because it is unfortunately prone to scratching and staining. Marble is porous and will absorb liquids and oils, leaving stains under the surface that can be very difficult to remove. The acidic nature of many substances around the house can instantly etch the stone. Fruit juice, sauces, soft drink and acidic cleaning products coming into contact with marble puts it in danger of permanent staining.
