- Marble is a metamorphosed limestone composed mainly of calcite or dolomite or a combination of these carbonate minerals.
- Marble is formed from limestone by heat and pressure in the earth’s crust.
- Recrystallisation of limestone occurs causing the texture and makeup to change. Impurities present during this process resulted in a wide variety of veining and colours. For example The purest calcite marble is white. Marble containing hematite has a reddish color. Marble that has limonite is yellow, and marble with serpentine is green.
- This recrystallisation process makes the structure of the rock more solid and enables the stone to take a high polish. Softer and more porous than granite, marble is more suitable to bathrooms more than kitchens.
