What are 3 facts about granite?
The word “granite” comes from the Latin word “granum,” which means “a coarse grain.” Granite got its name because of the grain-like patterns formed by its densely packed crystals. Granite has a density of around 162 pounds per cubic foot. Granite is one of the hardest substances in the world, second only to diamonds.

It is used as a construction material, a dimension stone, an architectural stone, a decorative stone, and it has also been used to manufacture a wide variety of products. Granite is used in buildings, bridges, paving, monuments, and many other exterior projects.
What you need to know about granite?
It is an igneous rock that formed millions of years ago, hardening from molten slag. The formation of granite occurs under intense heat and pressure beneath the earth. As a result, granite becomes strong, hard and dense. Granite falls into the natural stone category and has been used for years in numerous ways.
How long can granite last?
Granite countertops should last you at least 10-15 years if maintained well. While you can take steps daily to prolong the life of your granite; some professional help is needed to restore and refinish in order to ensure your granite surfaces last as long as possible.
What is granite made of?
Granite is a light-colored plutonic rock found throughout the continental crust, most commonly in mountainous areas. It consists of coarse grains of quartz (10-50%), potassium feldspar, and sodium feldspar. These minerals make up more than 80% of the rock.
Does granite cool quickly or slowly?
Granite and granodiorite are intrusive igneous rocks that slowly cool deep underground in magma chambers called plutons. This slow cooling process allows easily visible crystals to form.
What is granite made up of?
The chemical composition of granite is typically 70-77% silica, 11-13% alumina, 3-5% potassium oxide, 3-5% soda, 1% lime, 2-3% total iron, and less than 1% magnesia and titania. Volcanic rock of equivalent chemical composition and mineralogy is called rhyolite.
How old is granite?
300 million years ago
Granite is the oldest igneous rock in the world, believed to have been formed as long as 300 million years ago. Granite is also what's called a “plutonic” rock, meaning that it forms deep underground.
Is granite easily breakable?
It is, sadly, breakable. Don't expect granite to crumble and fall apart as the years go by. However, if you're swatting flies with a hefty pan and land your counter a good smack, it might chip a little. So if your counter's chipped after impact, there's nothing wrong with the stone and you weren't short-changed.

Can granite break easily?
Granite is a natural stone. It is very hard and durable, heat and scratch resistant, as well as, easy to maintain.
Can granite be left in the rain?
Yes, an outdoor granite countertop may require more frequent sealing, but it withstands freezing temperatures, prolonged direct sun, and rain, quite beautifully.
Does granite grow?
It is the oldest igneous rock (rocks formed by cooling lava or magma). Granite itself takes several million years to form. The longer it has to cool, the larger the crystals will be (because there is more time for the crystals to grow), and the shorter time it has to cool the finer the crystals will be.
Can granite be melted as lava?
The type of rock is important. If you were trying to melt Hawaiian basalt lava, it would not melt, but it would glow bright orange. If you were trying to melt granite or a mixed sediment (not pure quartz or calcite, which occurs on some beaches) it would almost certainly melt.
Is granite fast or slow?
Granite and granodiorite are intrusive igneous rocks that slowly cool deep underground in magma chambers called plutons. This slow cooling process allows easily visible crystals to form.
Is granite a poison?
The U.S. Environmental Protection Agency says most granite countertops are safe, adding little to a house's radon level.
Does granite break down in water?
The swelling of these clay minerals as they abosorb water further weathers the granite and biotite minerals in particular also undergo oxidiation, leading to the reddish color of grus deposits. Because hydration is the main chemical process breaking granite down, it follows that water plays a big role.
Is alcohol safe on granite?
Rubbing alcohol is a natural bactericide and can also kill fungus and viruses. It has no ill effects on your granite or the seal on your granite so it's an ideal way to keep countertops clean.
Does granite burn in a fire?
Granite Countertop – Can they burn? The simple answer is no, granite as a natural porous stone will not burn. Because it began as a liquid magma deep within the Earth, and over millions of years is cooled and compressed, it has a natural resistance to heat damage.
Can water mess up granite?
So can water ruin granite? No, but it can discolor it so you want to be cautious with especially hard water on your granite countertops.
