Quartzite is a very hard metamorphic rock that originated as sandstone. Through a process of high heating and pressurization, sandstone is transformed into Quartzite which is an extremely hard and durable natural stone. Quartzite tiles often have a wondrous sparkling texture as individual quartz pieces recrystallize in high heat. Its incredible strength makes it ideal for flooring applications. Quartzite tiles are easy to maintain and are an environmentally conscious flooring option.
