Quartzite is a decorative stone which is used as kitchen countertops, to cover walls, as roofing tiles, in flooring, and for stair steps.  This stone is predominantly silica, is a hard non-foliated metamorphic rock, which was originally sandstone and then converted into quartzite through heating and pressure deep in the earth. Its siliceous nature makes it a perfect choice for kitchen countertops because chemically it has a very high resistance to anything acidic and its resistance to water absorption, heat and scratching.
