Quartzite is a hard, metamorphic rock which was originally sandstone. Sandstone is converted into quartzite through heating and pressure usually related to tectonic compression within organic belts. Quartzite is strong and durable which makes it lasting building material for construction. Quartzite is resistant to wear and tear, has high abrasion, hardness and resistance to chemical attack. Being harder, consistency in dimensions and quality can be maintained with various finishes. The individual quartz grain recrystallize during the process and form an interlocking mosaic of quartz crystals.
