Fact #1: Granite is a naturally occurring rock .
Unlike other man-made surfaces (like quartz countertops), granite is naturally formed in the earth’s crust from the cooling of lava composed of quartz, feldspar, mica and various other minerals.
How is granite formed?
Granite is the most widespread of igneous rocks, underlying much of the continental crust. Granite is an intrusive igneous rock. Intrusive rocks form from molten material (magma) that flows and solidifies underground, where magma cools slowly. Eventually, the overlying rocks are removed, exposing the granite.
What is granite and how is it formed?
Granite is formed when viscous (thick/ sticky) magma slowly cools and crystallises long before it is able to reach the Earth’s surface.
Where is granite naturally found?
Granite is a light-colored plutonic rock found throughout the continental crust , most commonly in mountainous areas.
Where is granite used?
Building monuments. Granite used in jewellery . Granite used in fireplace mantle and floor. Granite used in bathroom skins, shelves, tabletops, basins.
Why is granite so special?
Granite is a gorgeous and unique natural stone. ... This is due to its mineral composition ; granite contains quartz and feldspar, as well as amphiboles, mica, and other minerals. The mineral composition of slabs varies, which is why each slab is unique in terms of its pattern and coloring.
Is granite a volcanic?
Granite. Granite, the equivalent of its extrusive (volcanic) rock type rhyolite, is a very common type of intrusive igneous rock. ... Granites can be predominantly white, pink, or gray in color, depending on their mineralogy.
Can granite melt?
If a rock is heated to a high enough temperature it can melt. In our lab we can heat granite to above 1000°C or 2000°F until almost all the crystals melt and dissolve together becoming a liquid.
How old is granite countertop?
Granite is the oldest igneous rock in the world, believed to have been formed as long as 300 million years ago .
Is granite a natural stone?
Granite is a natural stone which is formed in the Earth’s crust and is the result of the cooling of lava composed of minerals. The exact amount of minerals is what creates the different colors and patterns in the beautiful slabs of granite you see.
What are granite countertops actually made of?
Granite is an igneous rock made up of primarily quartz, feldspar, micas, amphiboles, and a mixture of additional trace minerals . These minerals and their variation in abundance and alteration give granite the numerous colors and textures we see in granite countertops.
What is an interesting fact about granite?
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. Granite is the main component that makes up the earth’s continental crust.
Is granite better than marble?
Hardness and Durability: Granite is harder than marble , so it is more resistant to chips and scratches. ... Both marble and granite countertops are quite durable, but ONLY if they are properly sealed every one or two years. Granite and marble are porous, so without a seal, liquids will penetrate and stain.
Why granite is used in kitchen?
Granite countertops stand out because they are comparatively much harder than marble . It is one of the most durable natural stones. ... Another plus is that granite is resistant to heat and can easily withstand hot cookware, which makes it a perfect material for kitchen countertops.

How many years does it take granite to form?
Calculations show that such a volume of granite magma would take several millions of years to cool down from 900 degrees C to near 550-650 degrees C, where it would totally crystallize, and then finally to cool to the 25 degrees C temperature found at the earth’s surface.
