Granite, because of its hardness and 'inertness' (means doesn't react with other materials such as acids), is an easily maintainable surface. For years granite has been used as an external cladding surface in commercial buildings because of its ability to withstand nature's elements and retain its original beauty.


Granite is a tough, durable rock composed primarily of three different minerals. These minerals are easy to see due to their different colors. The white mineral grains found in granite are feldspar. It is the most abundant mineral found in granite. The light gray, glass-like grains are quartz, and the black, flake-like grains are biotite or black mica.


What many people may not realize is that granite is actually radioactive. Since granite is a natural stone, it has a small amount of radioactivity to it, but it is so small that it poses no threat or health risk to humans. Don’t worry, if you have a granite countertop you won’t suddenly see your food mutating into something else.


Granite is one of the hardest substances in the world. The only thing you can find harder than granite is a diamond. This is what makes granite so popular as a countertop material. It’s extreme durability and because it cannot be damaged by scratching is a major plus. With granite countertops you can cut directly on its surface because it is so hard and durable.


Granite medallions. Medallions are basically granite mosaics. Designs and patterns are cut and fitted onto one, large tile so it installs as one piece. Granite medallions can be used on the floor or wall, inside or outside the house. Install a medallion in the entryway or even on the shower or pool floor.


Granite is generally made of biotite, plagioclase, quartz and amphibole, and will sometimes contain potassium feldspar.  In the late 1930s, it became apparent that a vast majority of workers had died from silicosis and tuberculosis as a result of granite dust or quartz exposure.  Dust controls were issued shortly thereafter by the Vermont Division of Industrial Hygiene and studies have shown that these measures have dramatically reduced, even eliminated, death from silicosis and tuberculosis (Costello and Graham, 1988).  More recent findings that lung cancer mortality has increased among certain workers in the Vermont granite industry have not been linked with granite dust (Graham, Costello and Vacek, 2004).  In the 1950s, evidence of environmental damage could be found in the Winooski River.  Cutting granite with the use of water created waste which drained into nearby rivers affecting stream quality and fish populations.  It seems plausible, if not likely, that this is happening to a certain extent today, particularly since water continues to be used in the production process.
