Quartzite is a metamorphic rock, or in other words, a rock that has been changed from one type to another under extreme heat, pressure, and time. For quartzite, it starts out as sandstone.
Quartzite is made of mostly quartz; the quartz is recrystallized while silica in the stone binds it together. Most quartzite is formed near tectonic activity, where heavy movement in the earth’s crust to move and create mountain ranges, occurs. The result is a stronger, harder, though more brittle material, that is difficult to scratch or etch; ranging at about 7 on Mohs hardness scale.
Aesthetically, quartzite is hard to beat. With the beauty and fluidity of marble and incredible hardness of granite, it has become another popular choice for kitchen counter tops. While pure quartzite typically ranges in the white to grey colors, “impurities” in the stone can result in colors from reds and pinks, browns and tans, blues and greens, and anything in between.
Quartzite can be used for both residential and commercial purposes, and can be fabricated for counter tops, fireplace surrounds, wall cladding, etc.; with finishes in polished, honed, brushed, and leathered. It is recommended for indoor use or restricted exterior use where it would not be exposed to freeze/thaw or heavy environmental conditions. MMG always recommends sealing your quartzite to protect it and make it more resistant to staining and easier to clean.
On a scale between economic to exotic, Quartzite tends to carry a higher price tag, not only due to its desirable appeal, but also to its complexity in handling and fabrication. The final product, however, is a showpiece worth talking about.
