Quartzite is a hard metamorphic rock which was once sandstone. Sandstone is converted into quartzite through heating and pressure.
Quartzite in its pure form is usually white to grey, though quartzites often occur in various shades of pink and red due to varying amounts of iron oxide. Other colors, such as yellow and orange, are due to other mineral impurities.
Quartzite is a versatile landscape stone and is generally used in a natural cleft state. It has a tough durable surface, and an excellent choice for high traffic areas.
Quartzite is generally available as a flagging as well as an irregular stand up product.
