Granite contains three main minerals – quartz, alkali feldspar, and plagioclase feldspar. These minerals make granite white, pink, or light grey. Granite also contains small amounts of dark brown, dark-green, or black minerals, such as hornblende and biotite mica.
Granite is one of the oldest, most durable and most respected of building materials. It is typically the hardest of the dimensional stones and withstands the elements very well. It is best for kitchen countertops because it is scratch, stain and heat resistant. It is also suitable for flooring or paving, wall cladding and all other types of countertops. Granite is suitable for either exterior or interior applications.
