GRANITE

Granite is everywhere. You’ve seen it carved into beautiful sculptures in museums. You’ve seen it in impressive columns, magnificent arches, and thick, solid blocks. You’ve seen it on the faces of United States Presidents at Mount Rushmore. You’ve seen it in walls, walkways, fireplaces, floor tiles, and countertops. You know it’s a beautiful majestic, stately stone. 

It is an igneous rock, which means that it was formed from molten lava deep within the earth’s crust. As the lava cools, it crystallizes under enormous pressure. It’s this crystallization that forms granite’s signature speckles of color — the longer the molten rock has to cool, the bigger the speckles, or grains, of color.

     In fact, that’s where granite gets its name: from the latin word “granum”, or grain. For the most part, it is made up of quartz and potassium feldspar, but it gets its wide variety of colors from other trace minerals present in the molten stone. Pink and red come from the presence of potassium feldspar, while white and gray come from quartz. Black and green are due to amphibole, while yellow comes from muscovite and brown from biotite. Mica is often commonly found in it as well, and can also be responsible for dark gray or brown grains, as well as any shiny, light-catching speckles you may see.

     Granite is incredibly hard and durable, which is why it’s such a popular building material. It’s resistant to scratching and weathering, and it can bear a lot of weight, making it a prime material for making buildings, walls, columns, pavers for roadways, and more. These properties are also why it’s such a great material for home use. Floor tiles made of it won’t wear away even under heavy traffic, and countertops are extremely resistant to knife scratches, chipping, and acid erosion. So, it can pretty much withstand anything you can throw at it, and it’ll stay beautiful for ages to come.
