Indeed the rate of limestone deposits increases with the temperature. When hard water is heated, such as in a home water heater, solid deposits (scale) of calcium carbonate (limestone) can form. This scale can reduce the life of equipment, raise the costs of heating the water, lower the efficiency of electric water heaters, and clog pipes.READ MORE
· When the heat and pressure hits the limestone, calcite seed crystals form. With continued metamorphism, these crystal seeds, grow while any clay deposits in the limestone transform into silicate structures such as mica. Because marble is a fairly soft material, only a three on the Mohs hardness scale, it is easy to cut and carve.READ MORE
