Granite is an igneous rock. It is a result of tectonic plates moving across each other creating molten magma chambers. Crystals are formed as these chambers of molten rock slowly cool. It is in these chambers, under tremendous heat and pressure, where granite was formed millions of years ago.

Granite is primarily made of Quartz (35%), Feldspar (45%) and Potassium. Granite provides a heavy crystalline and granular appearance with mineral grains. Granite is a very hard material and easier to maintain than marble, yet, it is still porous and will stain. There are different types of granite depending on the percentage mix of quartz, mica and feldspar. Black granite is known as an Anorthosite. It contains very little quartz and feldspar and has a different composition than true granite. Fine grained granites are often more absorbent than others; however, they are all extremely durable.

RESTORATION
Many natural stones are delicate and often lack long-term endurance. If a stone consumer is not pleased with the appearance of their stone due to heavy wear or improper maintenance procedures, Artisan Surface Systems®, a division of Wilson Building Maintenance, Inc., will design a restoration program for the consumer.


	The vitrification liquid is applied to the stone with steel wool pads. Following its application, a conditioner is applied to further improve the reflectivity created by the vitrification and also improve the slip and soil resistance. Artisan’s vitrification process will allow the stone to continue to “breathe” and not trap moisture into or below the stone which would cause damage over time. This process also extends the time span before restoration would be required.
	Diamond grinding is necessary to remove and flatten the lippage from uneven tiles and to remove deep surface scratches. This is completed with a 30, 70 and 120 grit diamond. The marks of the previous grit are removed by the consecutive use of the next higher grit.
	Honing is accomplished with a 220 and 400 grit diamond. Honing entails smoothing out the ground surface, thus leaving the stone without a reflection or shine.
	Polishing requires the use of 600, 800, 1800 and even 3500 grit diamonds. They brighten the surface by polishing the crystals, which also increases the reflectivity. The higher the grit, the higher the shine. It is imperative to use all of the diamonds in succession. Each diamond is designed to work after the previous one. A granite conditioner, can then be used to further enhance the shine.
