Granite slabs are the polished sheets of stone that your granite countertops start from.
Granite is also one of the hardest materials known. Quarried from mountains in Brazil, India, and Italy, to name a few, it consists of quartz, and feldspar. Granite is igneous meaning it formed naturally as molten rock millions of years ago. And though you’ll find a geological definition for granite, the commercial definition is quite broad.
All stones that perform, work, or behave like granite are called granite. The fact is, stones such as gabbro, diorite, and anorthosite are all called granite in the countertop world.
Available in many striking granite colors and patterns, granite is well suited for countertops and high traffic areas because of its durability and longevity. Other synthetic countertop materials scratch easily and can melt from placing hot items on them.
Granite, however, is heat resistant and nearly impossible to scratch. It will not stain under normal use and it’s unaffected by citric acid, wine, tea, coffee and most anything else. See Granite Care for tips on stone countertop maintenance.
Also, granite is one of the best surfaces for resisting bacteria, although competitors of granite surfaces have mounted a campaign to convince consumers of the inherent dangers of granite. Check out Radon From Granite Countertops to see the facts about radon and bacteria on granite.
The quality of granite counters goes well beyond the material itself. How the tops are made and how they are installed contribute to the benefits of granite countertops. Compared to quartz countertops, laminate, corian, and butcher block, granite has the highest overall rating of any countertop material.
