What is Granite?
Next to diamond, sapphire, and ruby, granite is the hardest natural product on earth. Once polished, natural granite will maintain its high gloss virtually forever. Normal use of kitchen knives, cutlery, and cookware leaves no scratches. Heat has almost no effect on natural granite, making it much safer than synthetic surfaces with polyesters and resins.
Granites usually are classified as igneous rocks obtained from molten masses or magmas. There is evidence that the origin of some granites may be attributed to regional metamorphism or pre-existing rocks. Rearrangement and re-crystallization taking place without a liquid or molten stage.
Granite is classified in (3) different groups:
Fine Grain : Fine grain granites are those in which the feldspar crystals average about 1/16 to 1/8" in diameter.
Medium Grain : In the medium grain granites the feldspar crystals average about 1/4" in diameter.
Coarse Grain : The feldspar crystals, in course grain granites average 1/2" and greater in diameter or several centimeters in maximum dimension. Coarse grain granites have a lower density.
Granite is used widely for kitchen countertops (in slab form). Although granite tiles may be used, it has been my experience that granite tiles are best used in kitchens as a backsplash to compliment the countertop or as an inlay in the backsplash to match the countertop slab and bring the backsplash tiles and the countertop together. Granite tiles are also used often as fireplace surrounds. Although the density and sturdiness of granite make it ideal for floors, the slick surfaces of polished granite tiles make it unsuitable for bathroom or kitchen flooring or any area which may collect water.
