How Is Marble Formed?
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).
