I. Common granite countertop myths

Some facts about granite have been misunderstood over the years, let’s set the record straight.

Myth 1: Granite is out, quartz is in

Truth: Nature is always in style! Both quartz and granite have their own benefits and unique aesthetics that can match perfectly with your home. Be sure to evaluate the special needs of the room your countertop will occupy so you can make the most appropriate choice.

Myth 2: Granite and marble are the same

Since they are both natural stones, you may have heard that granite and marble are almost interchangeable. But the two materials are actually quite different.

Truth: Because marble is a softer material than granite, more care is required to maintain its original luster and surface quality, and over time, a worn appearance or patina may develop in areas with heavy use.

Myth 3: Granite countertops require a lot of maintenance

Truth: Granite is resistant to stains, scratches, heat, and chemicals. It is one of the hardest countertop materials available, making it less susceptible to damage. Sealers are applied to natural stone such as granite to provide additional protection against stains.

Myth 4: Granite is unsafe for food preparation

Truth: Granite countertops are generally less porous than other types of natural stone and are often sealed, so they resist bacterial growth and are easy to keep clean.

Myth 5: Granite countertops release radon gas

Truth: Granted, radioactive substances such as uranium, thorium, and radium can occur naturally in granite, but this is also true of other rocks. These are simply byproducts of the natural decomposition of stones and rocks. Since granite is not very porous and is often used in well-ventilated areas such as kitchens or bathrooms, it is unlikely that the amount of radon it contains will escape in large enough quantities to cause a problem.

Myth 6: Granite may have cracks

Many homeowners mistake cracks for cracks.

Truth: Cracks are naturally occurring separations in the stone that do not compromise the structural integrity of the granite.

II. Interesting facts about granite

We cover the facts about granite that you should know when making your purchasing decision. Now, here are some fun facts about granite that you might not know! Let’s take a look at five interesting, little-known facts about granite.

1. The name of granite originates from Latin.

The Latin word “granum,” which denotes coarse grain, is where the name “granite” originates. Named for its coarse-grained structure, the grains reference the coarse-grained structure of this fully crystalline rock.

2. Granite is an igneous rock.

Granite doesn’t just naturally take on a flat shape. The stone was cut from the rock below the surface. While other types of rocks include sedimentary rocks (limestone, travertine, etc.) and metamorphic rocks (marble, quartzite, etc.), granite is an igneous rock that is created when lava cools and solidifies.

3. Granite has been around since ancient times.

Estimated to be 300 million years old, granite is both the oldest igneous rock in the world and one of the oldest rocks in existence. Granite existed 4.3 billion to 4.4 billion years ago, and granite means the existence of continents. This ancient granite has not yet been discovered; all has subsequently been eroded away or otherwise recovered. Ancient zircons are surviving remnants of crustal granite from Earth’s early days.

4. Granite is a naturally formed rock.

Unlike other man-made surfaces, such as quartz countertops, granite is formed naturally in the earth’s crust as molten rock composed of quartz, feldspar, mica, and various other minerals cools. Large chunks of stone were blasted out of the hillside and cut into the familiar flagstones we see at our favorite stone sites. The precise combination of minerals determines the color and pattern of your granite countertops.

5. Granite is composed of a variety of minerals.

Among the many minerals that make up granite are feldspar and quartz. Light-colored and possessing visible granules to the unaided eye, granite is an igneous rock. It is created by the gradual crystallization of magma beneath the surface of the earth. With trace amounts of mica, hornblende, and other minerals, quartz and feldspar make up the majority of the minerals in granite. Granite frequently has red, pink, gray, or white coloration due to this mineral composition, with black mineral grains visible throughout the rock.

6. The earth’s crust is rich in granite.

There are huge amounts of granite buried deep underground. Granite, known to science as plutonic rock, makes up most of Earth’s continental crust. Interestingly, the white mineral grains visible in granite are feldspar, the most abundant rock on Earth. Feldspar makes up approximately 60% of the Earth’s surface.

7. Granite is one of the hardest materials in the world.

In terms of hardness, granite is rated between 6 and 7 on the Mohs scale. Minerals are ranked from 1 to 10, with 1 being the softest and 10 the hardest, on this scale.

How strong is granite? Its density is approximately 73 kilograms per cubic foot, twice that of an equivalent volume of water. It is also one of the hardest substances in the world, second only to diamond (which ranks 10th).

Judging from the strength and durability of granite, Mount Rushmore is carved from granite, and Kanchenjunga in the Himalayas, the third largest mountain in the world, is also formed from granite.

8. Granite is naturally porous.

Is granite porous? The short answer to this question is yes. Granite is a porous natural stone. Like most other natural stones, granite is porous. This means that if it’s not sealed properly, liquids and stains can pass through the pores and down into the stone. If liquids or stains seep into the stone, it can cause damage and weakening of the granite. To prevent this from happening, it needs to be kept sealed.

9. Granite comes in many colors and styles.

When thinking of granite, many people think of white granite, black granite, or other common colors such as beige. Granite comes in these colors and more. Other color options include pink, green, blue, and more. Granite also comes in a variety of styles. From solid stone types to those with speckles or textures, they will all draw attention.

10. Blue and red are the rarest granite colors.

A variety of different minerals and rocks are what give each granite slab its unique color. The color variation of each slab is related to the amount of certain minerals in each batch—for example, the more quartz in a granite’s composition, the more milky it will look.

With this in mind, experts generally agree that granite slabs with red or blue tones are the rarest types of granite—and this is reflected in the cost of granite countertops on the market.

11. Granite is radioactive.

Like many other types of natural materials, granite contains trace amounts of uranium, however, unlike most other natural materials, some granite bodies are known to contain up to 20 times the normal amount of uranium.

Now, before you start canceling your quote on granite countertops, let us make it clear that the amount of uranium emitted by this material is less than the amount of uranium in your garden soil. Therefore, it is a completely safe material to use around the home!

13. Other surprising uses for granite

Granite’s value as a decorative and construction material is extremely high. In addition to being globally recognized as a modern and ancient tourist attraction, granite has been used to build railroads, including the Granite Railroad, the first commercial railroad in the United States. The first commercial railroad in the United States in 1825, the Granite Railroad connected Quincy, Massachusetts, to a dock on the Neponset River.

Blue Hone granite from Scotland is also used to create the curling stones that make the sport of curling possible. You can also find plenty of granite on climbing walls.

14. Granite is often used for indoor climbing walls.

Rock climbing is a fun, full-body workout, but it’s not a year-round activity. Luckily, indoor climbing gyms give climbers a space to practice. The rock walls for these gyms are usually made of granite, chosen for its durability and safety.

15. Granite forms the world’s tallest cliffs.

It is known that some of the highest cliffs in the world are formed from granite, including the Great Meridian in Pakistan, which was first climbed by Andy Selters and Scott Woolums in 1984. Great Trango Tower.

Not only does it create long-distance, technical alpine climbing routes for adventurers around the world, but at 8,586 meters above sea level, it also forms the third highest peak in the world, Mount Kangchenjunga, after Mount Everest at 8,848 meters above sea level and Mount Everest at 8,611 meters above sea level of K2.
