Marble is a metamorphic rock that forms when limestone is subjected to the heat and pressure of metamorphism. It is composed primarily of the mineral calcite (CaCO3) and usually contains other minerals such as: clay minerals, micas, quartz,pyrite, iron oxides and graphite. Under the conditions of metamorphism the calcite in the limestone recrystallizes to form a rock that is a mass of interlocking calcite crystals. Marble is usually a light-colored rock. When it is formed from a limestone with very few impurities it will be white in color. Marble that contains impurities such as clay minerals, iron oxides or bituminous material can be bluish, gray, pink, yellow or black in color.
Marble of extremely high purity with a bright white color is very useful. It is often mined, crushed to a powder and then processed to remove as many impurities as possible. The resulting product is called “whiting”. This powder is used as a coloring agent and filler in paint, whitewash, putty, plastic, grout, cosmetics, paper and other manufactured products. Being composed of calcite, marble is easy to carve and that makes it useful for producing sculptures and ornamental objects. The translucence of marble makes it especially attractive for many types of sculptures. At Shivalika Exports, we are engaged with some of the finest artisans and craftsmen which produce beautiful inlay design works and carvings.
