Granite Faqs

What is granite?  

Solid, durable, natural, warm and beautiful are only a few words that describe granite’s unique features. Granite is an igneous rock formed from the earth’s magma, which is composed of quartz, feldspar, mica and a variety of other minerals. Granite obtained its name from the Latin word “granum”, meaning grain, because it is coarse-grained and is classified as such by mineralogists. This grainy feature gives granite its unique texture.

Granite comes in a variety of colors including black, red and yellow based on where it was formed. Different types of finishes also create unique pieces of granite ideal for distinctive countertop surfaces.  

Granite, like other natural stones such as marble or limestone, is thousands of years old. Natural stones are porous, meaning that if they are not properly sealed they can be penetrated by water, oil and other liquids. Granite is the second hardest natural stone next to the diamond. Granite is strong enough for everyday use, making it an optimal material for countertops.

Where does granite come from?  

Granite comes from deep within the earth and forms through a process that can take thousands of years. Over time, liquid magma is forced between layers of rock and when it cools it forms a layer of granite. The granite acquires a crystalline look from the mineral elements that are left after the cooling process. This extremely long process makes granite into a hard and durable stone.   

Found in the earth’s continental crust, granite is the main rock that lies beneath the thin sedimentary veneer of the continents and forms throughout the world.      

Granite’s features are dependent on where in the world it was formed. Although granite is widely distributed throughout the world, commercially it is generally manufactured in Africa, Spain, India, Brazil, China and Norway.  Amazingly, experts are able to determine where a particular slab of granite came from based on its color. In most instances, red and black granite is commonly from Egypt or a desert in the United States, while white granite with gray specks is often from China and blue granite is usually from the African coast.   

The colors in granite are influenced by the minerals in each slab. For instance, quartz adds a milky white color, while feldspar contributes a blue or a green color to the granite. 

Can you tell me something about granite quarries?  

Granite is mined in quarries, which are large pits or excavation sites. The direction in which the granite will break the easiest determines how a quarry will be laid out in order to obtain the most amount of granite possible. 

At most quarries around the world, diamonds are used to cut the granite because the diamond is the only stone harder than granite.

The next step in quarrying granite is cutting it into desirable sizes, which is usually accomplished with wire saws. If the granite is to be used for countertops, it is cut and polished into appropriate shapes and sizes. 

What are the different types of granite finishes?

Granite surfaces can be finished in a variety of ways; polished, honed, flamed or brushed; each with its own unique look and texture.

A polished finish is most common due to a few key factors. Polished finishes will give your home an elegant and formal look. This finish is also a great option, especially for kitchens, because it is easier to maintain than other finishes and its shiny appearance brings out the color of your granite. Many people describe polished finishes as mirror-like.   

Honed finishes are gradually becoming more popular for granite countertops. This finish is smooth but less shiny than polished finishes and gives your home a more causal and contemporary feel. One drawback of honed finishes is that they are known to show stains more than others. But, don’t let this deter you from choosing a honed finish; as long as you make an effort to clean and care for your countertops, you should be fine. Certain sealers and treatments will also help keep your honed countertops stain free. As with all granite countertops and finishes, honed countertops are durable and will last a lifetime.    

Flamed finishes are made by exposing stone to intense heat followed by immediate cooling. This exposure causes granite to melt, and some crystals to shatter in the process, which leaves the granite surface highly textured. Flamed finishes are mostly seen in industrial places, although they are also a good choice for countertops in your home. Flamed finishes are a perfect solution if you need a surface that is slip resistant.

Brushed finishes (also known as antiqued finishes) are created by brushing the granite’s surface to obtain a worn-in look. This finish gives countertops a dramatic look.

How do I best maintain granite countertops?  

Once originally sealed, granite is easy to maintain. The initial seal is necessary because granite is porous and will stain easily without it. After sealing, your granite is protected and ready to use. Keep in mind that you will need to reseal your granite countertops at least once a year. This can be done on your own or by a professional, but will ensure that your granite will remain stain free. If a spill should occur, clean up before the stain has a chance to penetrate the surface. Granite is somewhat absorbent and can absorb stains if spills are left for any length of time.  

Generally, you can clean your granite countertops with a neutral cleaner and a soft clean cloth. Consider using a disinfectant cleaner made specifically for granite. With the growing popularity of granite countertops, these should be easy to find. Using regular cleaning chemicals on your countertop will strip the seal and leave the porous surface of the granite exposed. Don’t be afraid to call your local stone dealer for suggestions on maintenance, care and cleaning.

Can granite countertops be repaired?  

In most cases, if granite is cracked, it will need to be completely removed and replaced. 

What is the life expectancy of granite countertops?  

When granite enters your home, not only is it already thousands of years old, but it will probably last another thousand years. To begin with, granite is tough. It is stain, scratch and heat resistant, just to name a few of its impressive features.   

Experts say that using your granite countertops as a cutting board won’t hurt the countertops only dull your knives, and unless you try cutting granite with a diamond or smashing it with a sledge hammer, it won’t crack or break. Furthermore, it can withstand temperatures up to 900 degrees Fahrenheit (482.22 degrees Celcius ) without causing damage. These are just a few of the reasons why granite countertops can last a lifetime.

Do granite countertops add value to my home?  

Countertops made of natural stone, especially granite, add more resale value to your home than any other material. Second, granite countertops will last you a lifetime, which means that after the cost of the initial installation (with proper maintenance and care) they never need to be replaced.   

If you are set on granite countertops, but still have concerns about the costs there are several ways to lower the expense. One possibility is choosing granite based on the place from which it was imported. For example, some experts say that buying granite imported from Italy tends to be the most expensive option, while choosing granite imported from China can save you money.   

Even if granite countertops remain out of your price range, there is still hope for the future. As with any product, as its popularity rises and it becomes widely used, the price often lowers. Also, with new quarries being discovered each year, the growing choices keep prices down. 

What colors can I choose from?

Granite is not only a perfect material for countertops because of its durability, but also because of its aesthetic appeal. Granite can be elegant and luxurious, or casual and contemporary, depending on the color and finish you choose. Also, no matter what look you go with, you will be lucky to have countertops that will last forever and never dull.

Today there are countless colors of granite to choose from imported from all over the world. Each piece of granite is unique; no two slabs will ever look identical. From greens, blues and blacks, to pinks, whites and yellows, the options are endless. Slabs also vary in patterns – some have large and intricate designs and movements while others are more subtle.

So, what color will you choose for the granite in your home and what effect will it create?  Here are some of the most common colors and their basic styles.

Brown and Beige - These neutral tones easily compliment other colors in a kitchen or bathroom. They are the most popular choices, providing a comfortable and traditional look.

Yellow and Gold - Countertops brighten and warm-up a room.  Gold countertops also add warmth, along with a luxurious and rich style. 

Red - Granite can create a striking and romantic feel.  Reds will also draw people to the room and spice up the style in your home.

Black - Provides a very modern, clean and sleek look. Black granite countertops can be plain or can incorporate interesting patterns and additional colors.

Blue and Green - These tones are very vibrant and lively.  Bright greens and blues can give your room a rare and exotic feel. These colors are commonly found in mixes with other colors from whites to reds to blacks.

White - Depending on how the rest of the room is decorated, white granite countertops can provide a comfortable and soothing feel, or a more modern and elegant style.  White matches with almost all other colors and may make small rooms appear more spacious.

How do I install granite countertops?  

Granite countertops should be installed by a professional. Although hiring someone to install your countertops adds to the cost of the project, in the end, it is worth it to have the job done right. Installing granite countertops incorrectly can lead to serious problems and possibly the need for replacement.

What are the variations in thickness between granite slabs? Between different granite materials?  

Granite comes in a variety of thicknesses.  The most popular is a 3 cm thickness (1-1/4”) but it is also available in a 2 cm thickness (3/4”).  The weight of a slab is approximately 12-13 lbs per square foot in 2 cm thickness and 18-19 lbs per square foot in 3 cm thickness.  An 8-foot countertop slab 3 cm in thickness weighs between 144-152 lbs. The thicknesses can vary throughout the slab as much as +/- 3 mm.  Because granite is not a uniform thickness throughout the entire slab, installers compensate for the variations with additional support. Laminate is normally 1/8” thick panels attached to typically a ¾” thick wood product.  Solid surface material comes in three standard sizes ¼”, ½”, or ¾” thickness.   Soapstone is typically 1-1/4” in thickness, marble 1-3/4” to 2”, concrete 1-1/2” to 2”, and engineered stone comes in 1-1/4” thickness.

I am ready to buy my granite countertops! What is the first step?  

Although you may start by looking at granite color samples online or in a brochure, it is recommended that you go and see your choices in person before you make a decision. This is important since granite colors often look different in person than in photographs. The most common place to view granite samples is at a granite wholesale warehouse.

Make sure that you view the granite samples in adequate lighting. Also, if remodeling your kitchen, you may want to bring along a kitchen cabinet door or a sample to match your granite to.   

By seeing the granite in person, you will know exactly what it will look like in your home. Some providers will even let you choose the exact slab that will be installed in your home! Remember that granite is likely to last a lifetime, so take your time and enjoy the process.

Dragline Excavator $93.99 Dragline excavation systems are heavy equipment used in civil engineering and surface mining. In civil engineering the smaller types are used for road and port construction. The larger types are used in stripmining operations to move overburden above coal, and for tarsand mining. Draglines are amongst the largest mobile equipment (not waterborne), and weigh in the vicinity of 2000 metric tonnes, though specimens weighing up to 13,000 metric tonnes have also been constructed. A dragline bucket system consists of a large bucket which is suspended from a boom (a large trusslike structure) with wire ropes. The bucket is manoeuvred by means of a number of ropes and chains. The hoist rope, powered by large diesel or electric motors, supports the bucket and hoistcoupler assembly from the boom. The dragrope is used to draw the bucket assembly horizontally. By skillful manoeuvre of the hoist and the dragropes the bucket is controlled for various operations. A schematic of a large dragline bucket system is shown below.
