Granite is a coarse-grained igneous rock made up primarily of quartz, alkali feldspar, and plagioclase. It is formed by magma with a high silica and alkali metal oxide content that slowly cools and solidifies underground. Granite is one of the world’s hardest materials, second only to diamonds. Granite is so tough and durable that the pedestal on which the Statue of Liberty stands is made of it. Since the Ancient Egyptians, granite has been used in construction. Most people are aware of granite because it is the most common rock found on Earth’s surface and is used to make several objects that they come across in their day-to-day lives. Counter tops, floor tiles, paving stone, curbing, stair treads, building veneer, and cemetery monuments are all made from it.
