Find articles, information, and resources on marble below. Marble is formed from limestone. The heat and pressure in the earth's crust changes the texture and the composition of limestone to form large grains of calcite. This is called recrystallization. Many natural stones, including limestone and travertine, are referred to as marble. Many stone experts separate limestones, travertines, and onyx marbles as individual groups from commercial marbles. Marbles in a narrower commercial sense are softer natural stones than granite, and more dense than limestone or travertine. Marble takes a good polish and is used for more graded purposes - mainly polished facing and flooring. Marble is a recrystallized limestone that formed when the limestone softened from heat and pressure and recrystallized into marble where mineral changes occurred. The main consistency is calcium and dolomite. Ranges in many colors and is usually heavily veined and shows lots of grains. Hardness rates from 2.5 to 5 on the MOH Scale. More or less crystallized by metamorphism, Marble ranges from granular to compact in texture, is capable of taking high polish, and is used especially in architecture and sculpture (as hardness, coldness, or smoothness).
