One of the most popular and widely used materials for countertops is granite. Harder than marble, and with a wide variation in its patterns, this sturdy rock is one of the most suitable options for kitchen and bathroom use.

How is granite formed?

The term “granite”, when used commercially, refers to any type of crystalline rock formed from mineral grains that were compressed and subjected together to high temperatures. Because of the way they were created, these rocks are much harder and tougher than sedimentary rocks. The latter are formed by the compression of sediments under less extreme conditions, and include such varieties as limestone and sandstone.

The nature of its formation makes granite an igneous or metamorphic rock. Marble also falls under the same category, but is not as hard as granite. While granite and marble have very similar qualities, one property that officially sets them apart is hardness.

True Granite

To a geologist, however, true granite is not one that was formed from other rock particles, but from different minerals in liquid form, cooling to become rocks under the earth’s surface. Its mineral components include quartz and feldspar.

Other stones, such as gabbro, pyroxenite, and schist, are stone varieties different from granite, but are sold commercially under the general category of “granite”. Regardless of the variety, commercial granite can be expected to provide the same qualities of sturdiness and beauty that has made it a much sought after material for the home.
