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.
