WHAT ARE GRANITE SLABS?
Granite is called a felsic rock because it is rich in feldspar and quartz. It also contains mica and horneblend, which is a dark type of silica. Depending on the composition of the slab, it has varying combinations of pink, gray and white. For a slab of igneous rock to be classified as granite, it has to be made up of at least 65% alkali feldspar and 20% quartz.
Some slabs that may look like granite but do not contain these minimum amounts of feldspar and quartz are prefaced with the terms “granitoid” or “granitic.” The distinction can be important in determining the hardness of the slab. Granite has become popular in construction precisely because it is hard and tough.
What are the advantages of granite as countertop material?
Durable and low maintenance
Because granite crystals are interlocked, it makes it harder to take apart. This makes it ideal as material for countertops because it does not easily scratch, even if you use a knife on it. It is not proof against a sledgehammer or other deliberate attempts to cause damage, of course, but otherwise it is hardy enough to last as long as the house remains standing, and perhaps much longer than that.
This interlocking structure also reduces the porosity of granite to the point that it is generally stain proof, so it is easy to clean and sanitize. However, many granite slabs may have micro fissures that will cause small irregularities to appear on the surface. Commercially prepared granite is sealed to smoothed out these irregularities and to make it even more durable and low maintenance. At most, you may need to reapply the sealant once in a while.

You may decide on a slab because you like the color combination or the pattern, but it does not hurt to know why it happens to be that way. Here are the crystals that determine the color of your granite countertop. See if you can identify each one.
Last, but certainly not least, a big advantage of granite for countertops is affordability. It is not the least expensive of countertop materials, but it has far more to offer. For one thing, it can stand more abuse and requires less maintenance than tile or wooden countertops. For another, it is much easier to install a granite countertop than tiles. Finally, it is far safer to have granite as your kitchen working area than any other countertop material because of its relatively non-porosity.
Another good reason to choose granite is it is less expensive than marble. However, with the right markings and polishing, granite can easily be mistaken for its more expensive cousin. If you are striving to create a high-end look, but your budget simply will not accommodate marble, granite is your best possible option. In addition, granite is much more durable than marble, so you are hitting two birds with one stone. You get the look of marble, but not the problems that go with it.
There is so much to like about granite countertops that it is no wonder that it is the top choice of architects, interior designers, and homeowners. Your biggest problem is choosing just the right one to go with your décor.
