Granite Products

Granite is a very hard, igneous stone formed out of volcanic activity. As magma from the volcanoes cooled very slowly (over millions of years), mineral crystals in the magma deposits grew. Those minerals-primarily hornblende, feldspar, mica, and quartz-are what give the granite its grainy texture. When the softer earth around the resulting granite deposit eroded, the harder rock became exposed, making it available for quarrying in nearly every region of the world. The igneous rock is determined by its rate of cooling, the further below our planets surface the granite was formed, then the slower it cooled, resulting in the creation of larger crystals, and in general, producing a lighter color. The nearer to the earth's surface the granite was formed, the quicker it cooled, resulting in smaller, stronger crystals, producing darker colors. These are in general the strongest type of granite.
