Marble
Metamorphic stone such as marble originates from a natural change from one type of stone to another type through the mixture of heat, pressure, and minerals. The change may be a development of a crystalline formation, a texture change, or a color change.
Marble: A recrystallized limestone that formed when the limestone softened from heat and pressure and recrystallized into marble where mineral changes occurred.
The main consistency of marble is calcium and dolomite. Marble ranges in many colors and is usually heavily veined. Usually very sensitive to staining.. Hardness rates from 2.5 to 5 on the MOH Scale.
It is very important to begin taking care of marble both before installation and after with proper stone care products.
Restoration is often required on neglected or improperly treated marble. Marble is very sensitive to both acid and alkali.
Marble can be polished, honed, or tumbled. For tumbled marble the color can be enhanced using a Stone Color Enhancer.
Marble is classified into three categories:
- Dolomite: If it has more than 40% magnesium carbonate.
* Does not provide a high polish; however, it is a very
durable marble.
- Magnesian: If it has between 5% and 40% magnesium carbonate.
* Usually provide a finish with less polish and reflectivity
and are more durable than calcite marbles.
- Calcite: If it has less than 5% magnesium carbonate.
* Calcite marbles provide the highest polish; however,
they are more sensitive to acids and alkali chemical
