FAQ/Q&A
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:
  • FINE GRAIN: Fine grain granites are those which the feldspar crystals average about 1/16 - 1/8" in diameter.
  • MEDIUM GRAIN: Medium grain granites are those in which the feldspar crystals average about 1/4" in diameter.
    • 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.

      What is Marble?

      Marble is a metamorphic rock resulting from the recrystallization of limestone. The term marble is loosely applied to any limestone or dolomite that takes a good polish and is otherwise suitable as a building stone or ornamental stone. Marbles range in color from snow-white to gray and black, many varieties being some shade of red, yellow, pink, green, or buff; the colors, which are caused by the presence of impurities, are frequently arranged in bands or patches and add to the beauty of the stone when it is cut and polished.

      Will my order be identical to my sample?

      Although our granite and marble samples are intended to represent the respective stones as closely as possible, our stones are quarried at varying times therefore it is possible for colors and veining to vary slightly from samples you view. Furthermore, a slab of stone will usually have a certain amount of color variation from one end to the other. These variations are the artmanship of nature and are what give the stones their eye-appeal.

      What is the difference between granite and marble, and which should i choose?

      Although both granite and marble are earth born stones, they are not completely equal. Granite is developed under high temperatures deep in the earth making it a very hard, resistant stone--the 2nd hardest stone, in fact. Marble is formed at the bottom of bodies of water, solidifying over millions of years. Marble is made up mostly of calcium, therefore it can be affected/damaged by exposure to acids such as vinegar. Because of the differences in the stones you may consider granite to be more economical a choice in the kitchen; however both stones are very durable when maintained and cared for properly.

      Is it necessary to seal stone?

      Granite and Marble are porous mineral stones that easily absorb liquid which can cause discoloring and staining. All marble and granite surfaces are sealed after they are installed to fill the pores and prevent the stone from being exposed to liquids. Depending on how much use your surfaces get, and how well maintained your surfaces are It may be necessary to reseal them after a course of time.


    • Natural Stone FAQ's:

      Natural stone purchased for your home or business is an investment that will give you many years of beautiful services.
      Stone is a natural product and simple care and maintenance will keep it looking beautiful.

      Here are some recommendations for routine care and cleaning.

      Precautions

    • Use coasters under all glasses, particularly those containing alcohol or citrus juices. Many common foods and drinks contain acids that will etch or dull the stone surface
    • Do not place hot items directly on the stone surface. Use trivets or mats under hot dishes and placemats under china, ceramics, silver or other objects that can scratch the surface.

    • Cleaning Procedures & Recommendations

      Floor Surfaces

      Dust mop interior floors frequently using a clean non-treated dry dust mop. Sand dirt and grit do the most damage to natural stone surfaces due to their abrasiveness. Mats or area rugs inside and outside an entrance will help to minimize the sand, dirt and grit that will scratch the stone floor. Be sure that the underside of the mat or rug is a non-slip surface. Normally, it will take a person about eight steps on a floor surface to remove sand or dirt from the bottom of their shoes. Do not use vacuum cleaners that are worn. The metal or plastic attachments or the wheels may scratch the surface.

      Other Surfaces

      Clean stone surfaces with a few drops of neutral cleaner, stone soap (available at hardware stores or from your stone dealer) or a mild liquid dishwashing detergent and warm water. Use a clean rag mop on floors and a soft cloth for other surfaces for best results. Too much cleaner or soap may leave a film and cause streaks. Do not use products that contain lemon, vinegar or other acids on marble or limestone. Rinse the surface thoroughly after washing with the soap solution and dry with a soft cloth. Change the rinse water frequently. Do not use scouring powders or creams; these products contain abrasives that may scratch the surface.

      Bath and Other Wet Areas

      In the bath or other wet areas, soap scum can be minimized by using a squeegee after each use. To remove soap scum, use a non-acidic soap scum remover or a solution of ammonia and water (about 1/2 cup ammonia to a gallon of water). Frequent or over-use of an ammonia solution may eventually dull the surface of the stone.

      Vanity Top Surfaces

      Vanity tops may need to have a penetrating sealer applied. Check with your installer for recommendations. A good quality marble wax or non-yellowing automobile paste wax can be applied to minimize water spotting.

      Food Preparation Areas

      In food preparation areas, the stone may need to have a penetrating sealer applied. Check with your installer for recommendations. If a sealer is applied, be sure that it is non-toxic and safe for use on food preparation surfaces. If there are questions, check with the sealer manufacturer.

      Outdoor Pool & Patio Areas

      In outdoor pool, patio or hot tub areas, flush with clear water and use a mild bleach solution to remove algae or moss.

      Do's and Don'ts

  • Do dust mop floors frequently
  • Do clean surfaces with mild detergent or stone soap
  • Do thoroughly rinse and dry the surface after washing
  • Do blot up spills immediately
  • Do protect floor surfaces with non-slip mats or area rugs and countertop surfaces with coasters, trivets or placemats
  • Don't use vinegar, lemon juice or other cleaners containing acids on marble, limestone, travertine or onyx surfaces
  • Don't use cleaners that contain acid such as bathroom cleaners, grout cleaners or tub & tile cleaners
  • Don't use abrasive cleaners such as dry cleansers or soft cleansers
  • Don't mix bleach and ammonia; this combination creates a toxic and lethal gas
