Marble is a metamorphic rock, resulting from the metamorphism of limestone, composed mostly of calcite. When the limestone is heated under pressure in the ground, its calcite is melted, and the large crystals form into marble. As with granite,
the rock is subject to millions of years of earth’s natural forces, and it is these forces which determine the final colour.

Being slightly softer and more porous than granite, the most common use for marble in residential applications is in the bathroom, as the marble can be polished to a very high, consistent finish for vanity tops, bath surrounds and cladding for shower areas. It is often used for window-cills in conservatories and sun-rooms, and some fireplace applications. Historically marble has been used on many famous statues and tombs, such as the Venus de Milo and the Taj Mahal.
