Quartzite is a hard metamorphic rock. It is formed when sandstone is squeezed and heated under a chain of mountains. Although pure quartzite is white, it usually occurs in shades of pink and red. This happens when it contains some iron oxide (Fe2O3). Other colours, such as yellow and orange, are due to other mineral impurities.

     When sandstone is changed to quartzite, the individual quartz grains and cement material recrystallizes. Most of the original texture of the sandstone is destroyed by the metamorphism. Minor amounts of cementing materials, iron oxide, silica, carbonate and clay, often move when this is happening. It causes streaks and lens shapes to form in the quartzite. When heated, individual quartz pieces recrystallize giving it a beautiful and decorative sparkling pattern. Quartzite is ideal for any countertop surface due to its strength and long-lasting composition. When deciding on what to use for your next countertop surface, consider quartzite countertops for its strength, beauty, and overall durability.
