Marble is a metamorphic rock resulting from the metamorphism of limestone formed under immense heat and pressure. The mainly calcite composition is recognised by its characteristic swirls and veins deriving from various mineral impurities originally present as grains or layers in the limestone. Of mid-range hardness (approx. MOHS 3–4), marble is ideally suited for bathroom tops, walls and flooring. Marbles uniqueness makes it desirable for kitchen tops, but care and maintenance needs to be a consideration when choosing this stone.
Marble is traditionally used internally in a high polished, mirror like finish however is now also appreciated externally in a variety of finishes such as honed, brushed and sandblasted with a vast range of colours and patterns available.
