Granite
An excellent choice for kitchen countertops, floors, and other heavily used surfaces

Granite, quarried from the mountains of Italy, the U.S., India, and dozens of other countries around the world, is one of the most popular natural stones on the market.

Available in a striking array of colors, granite's durability and longevity make it ideal for kitchen countertops and other heavily used surfaces, including table tops and floors.

While some synthetic surfaces scratch easily and melt under hot cookware, granite resists heat. Granite is also one of the most bacteria-resistant kitchen surfaces, and it is not affected by citric acid, coffee, tea, alcohol, or wine. It is also nearly impossible to scratch, and with proper cleaning, will not stain under normal use (ask your professional contractor about sealants available to further improve resistance to staining).

A leading consumer magazine recently compared granite with engineered stone, ceramic tile, laminate, butcher block, and other manufactured surfaces. Granite received the highest overall performance rating as a kitchen countertop material.

Because of its exceptional strength, granite is well suited for exterior applications such as cladding, paving, and curbing.

Granite, igneous rock of visible crystalline formation and texture. It is composed of feldspar (usually potash feldspar and oligoclase) and quartz, with a small amount of mica (biotite or muscovite) and minor accessory minerals, such as zircon, apatite, magnetite, ilmenite, and sphene. Granite is usually whitish or gray with a speckled appearance caused by the darker crystals. Potash feldspar imparts a red or flesh color to the rock. Granite crystallizes from magma that cools slowly, deep below the earth's surface. Exceptionally slow rates of cooling give rise to a very coarse-grained variety called pegmatite.
Granite has greater strength than sandstone, limestone, and marble and is correspondingly more difficult to quarry. It is an important building stone, the best grades being extremely resistant to weathering.
Normally granite is classified in three different groups:

COARSE GRAIN: Coarse grain granites are those in which feldspar crystals average 1/2" , and greater diameter or several centimeters in maximum dimension. Coarse grain granites may have a lower density.
