الوصف

Marble is made up of metamorphic rocks that are resulted from the recrystallization of limestone softened from heat and pressure. The main constituents are calcium and dolomite, and hardness ranges from 2.5 to 5 on the MOH scale. They are usually a light-colored rock and come with a considerable range of colors and hues such as bluish, gray, pink, yellow, or black. When a Marble is formed from limestone, they have very few impurities, and these marbles come in white color. A marble with some impurities of clay minerals, iron oxides, or bituminous material imparts hues to the marbles. High purity marble has a bright white color, is very useful, and is often mined, crushed to a powder. Finally, they are processed to remove the impurities caused by natural impurities such as sand or clay minerals as possible. The final retrieved product is called whiting. The whiting powder is widely and extensively used as a coloring agent and filler in paint, whitewash, putty, plastic, grout, cosmetics, paper, and other manufactured goods.
