Granite is a common type of igneous rock that is granular in texture. Granites can be predominantly all different colors but with some black, depending on their mineralogy. The word “granite” comes from the Latin granum, in reference to the coarse-grained structure. Strictly speaking, granite is an igneous rock with between 20% and 60% quartz by volume, and at least 35% of the total feldspar consisting of alkali feldspar, although commonly the term “granite” is used to refer to a wider range of coarse-grained igneous rocks containing quartz and feldspar.
Granite is a great option for countertops, as it is one of the hardest surfaces in nature. It is perfect for outdoor use as well. Most granites require a coat of sealer once or twice a year, which is a simple process that can be done by the homeowner to protect it from absorbing any liquid. Granites come in a large variety of colors to coordinate with all sorts of color palettes.
