What's the difference between Granite and Marble?

Although both are stones and both are quarried from the earth, granite and marble are very different from each other. Granite is formed in the earth's mantle at extremely high temperatures, and is a very hard, resistant stone. The marble family, limestone, travertine, marble, onyx, starts out as sediment, animal skeletons, shells, plant matter and silt at the bottom of bodies of water. After millions of years this solidifies into stone (lithifies). Because its main component is calcium, it can be affected by acids such as vinegar and citrus beverages.

Should I use Granite or Marble for my kitchen counter tops?

Although typical application of marble is for bathroom vanity tops, Jacuzzi tops and fireplaces, it is possible to use it in the kitchen. However, we don't recommend it due to the fact that it is easy to scratch and can be etched by acidic substances, such as vinegars, ketchups etc. The high-gloss of the marble countertop can be partially lost as many chemicals etch its surface. Granite in turn is considered the second hardest stone; its polish is not subject to etching by household acids, or scratching by knives, pots and pans under normal use. It is also not affected by typical kitchen heat such as hot pans.

Is it necessary to seal stone?

Since most mineral surfaces are porous they absorb liquids, which may result in discoloring and staining. Although there are many commercial grade products available on the market which may bring the stone to its original luster, taking simple precautions and regular maintenance can save a lot of trouble and cost. All of our marble and granite tops are sealed immediately after they are installed. The impregnating substance penetrates the stone clogging most of its pores making it quite impervious to alcohol, juices, soft drinks, cosmetics, cleaners, coffee, food and even oil. With the course of time, depending on how heavily the tops are used, the sealer gets worn out. The clear indication of this happening would be the fact that the liquids are easily absorbed into the stone leaving temporary (if promptly wiped off) stains. You should re-seal your marble every six months and your granite every 12 to 24 months. For best results, it is recommended to use the same sealer which was used initially.

What is the best way to clean natural stone surfaces?

An old and inexpensive method of cleaning granite tops is to use warm water mixed with dish detergent. It is important though, to make sure that the surface is thoroughly rinsed afterwards, to prevent soap scum buildup.

Can I cut on my countertop?

If your countertop is made of granite, you can. Granite is extremely hard and can withstand even the sharpest knives. It's not a good thing for your knives though. They can get dull in as little as one use. We recommend using a wooden or plastic cutting board. Other stones are not as resistant to scratching and so we do not recommendcutting on them.

Can stone cantilever? What is the maximum overhang size?

You can cantilever granite up to 14" with sufficient support on the fixed end and with a large enough piece. Never cantilever unsupported granite where it might receive excessive stress like someone sitting on a counter or stepping on a counter. You must have support underneath for these situations. Other types of stone are not as strong and cannot be cantilevered as much.

Can damaged piece of stone be repaired?

If any damage occurs it can usually be fixed with a mixture of epoxy and ground up chips of stone. In most cases the repair is hard to spot.

Can you polish a material that is honed, like limestone?

Certain materials, like marble, limestone, slate, and travertine, have honed finishes because they are not dense enough to create a fully polished surface. Stones like this cannot be polished. Additionally, granites that come in Honed surfaces usually are also available polished, so you can avoid the costly polishing process.

Can granite surfaces be damaged?

Like any solid surface, high impact blows can harm granite. Because of its crystalline structure, it can chip if subjected to sharp tipped hard objects. Unsealed, granite can absorb stains such as oil, which can ultimately cause dark spots or discoloration. Fortunately, under typical household use, granite is not subjected to such events. Also, heat from pots and pans or burning liquids will not affect granite under normal circumstances

Does granite stain?

Most natural stones are porous to some degree. Granite has very little porosity. Most colors will never show any moisture. A few colors may show some moisture if exposed for a period of time. For example, a puddle of water left on the counter for 30 minutes for some colors, may show a dark spot when the water is wiped away. This spot will then dry up and no evidence will show. Only a few colors demonstrate this trait.

Can marble be used as a kitchen countertop?

Most marbles are too soft and porous to be safely used in the kitchen. Even the more resilient marbles are susceptible to staining and should be avoided if you intend to cook or serve food often.

Where can I use marble?

Marble can be used for a number of applications such as fireplace surrounds, tabletops, saddles, and shelves. It can also be applied in the bath area as Jacuzzi surrounds, vanities, floor, and shower paneling. Generally you can safely use marble in low traffic areas

Are there differences in hardness between stones?

Yes there is, generally limestone, sandstones and soapstone are the softest followed by marbles and granite stones. There are also hardness variations within each stone category. Among the granites the softest will tend to be the lighter colors and the harder ones will be the darker colors though even the lighter colors in granite are extremely hard.

Does granite burn?

No. You can't burn granite with ordinary use. It is perfectly ok to set hot pots or pans directly from the stove or oven onto granite. Granite holds up extremely well under heat, but thin strips of granite do not have enough surface area to absorb all of the heat from dishes, pots, and pans adequately.

Doesn’t granite require a lot of care?

There are many products in the market you can use to clean your granite countertop but mild soap and water is usually sufficient for daily cleaning. A few times a year we recommend to use a professional stone cleaner. Which will thoroughly clean and polish your natural stone and help protect and reseal the surface. These cleaners are available at most supermarkets.

What’s the best way to clean marble and other soft stones?

The old rule of thumb is never to use anything you wouldn’t use on your hands. Never use powdered cleansers or abrasive pads to clean your stone. Even "soft scrub" type cleaners contain pumice, which is powdered volcanic stone, and might damage your stone countertops or floors. Never use any product which is acidic; this includes substances like ammonia or many common liquid cleaners such as Windex. You should always use sealers and cleaning products designed specifically for natural stone.

What is etching?

Etching happens when acid in some form comes in contact with a polished marble or limestone surface. This causes a chemical reaction, which removes the polish, or roughens the surface of honed marble or limestone. Green marbles, such as the "jades" from China are resistant to etching, and granite is impervious to any common household acids

Does granite have any fissures or pits?

Yes, granite has fissures and/or pits due to the original natural stone structure. Though pits can be minimized through proper polishing, sealing and finishing of the stone some types of stone have more pits and fissures than others as a result of their individual crystalline structures.

Why are some stones more expensive than others?

Availability, locations of quarries in the world (due to transportation expenses), the rarity of the color, and the amount of labor required to extract the stones all affect the price of natural stone. Higher price doesn't mean higher quality.
