Marble Polishing Process
Before we get into the process of marble polishing, it is a good to get an understanding of what is marble. Marble is a natural stone that comes from the metamorphism of carbonate, sedimentary rocks. Typically, these are dolomite or limestone. During the metamorphism, re-crystallization occurs in the carbonate mineral grains. The rock that is produced through this process has interlocking carbonated crystals. The original sedimentary structures of the rock as it existed prior to this change are often destroyed or changed.
Now a basic understanding of marble for everyday use: Marble is a calcite which means that is made up mostly of calcium; it is very sensitive to acidic products such as vinegar containing household liquids, general purpose cleaners and other chemicals. Marble is a very soft rock that scratches very easy making it a high maintenance material.
The good news is that when a marble floor, marble counter top or marble becomes damaged it can be repaired or restored at fraction of the replacement cost.
