Granite is an igneous rock of volcanic origin composed of 30% quartz, 60% feldspar, and 10% Mica. This gives it a high range of hardness. It is very resistant to high wear, and has superior abrasion resistance and compressive strength. It is available in a wide range of colors. Granite used to be available only in a homogeneous grain, however it is now available in veined and patterned varieties. Granite is an excellent material for internal and external building use because of its hardness and resistance to all types of weather.
