Whereas granite is an igneous rock found more abundantly than quartzite, deep in the earth's crust, providing the base for the many continents' sedimentary rock, quartzite consists of a larger volume of quartz than granite; under heat and pressure combined, quartzite is formed from sandstone and quartz, and with the amount of pressure undergone, empty grains of sandstone are stuffed with quartz. This means quartzite is actually harder. On the Mohs scale of hardness, from 1 to 10 with 10 being the hardest, granite measures in at around 6-6.5, and quartzite measures in at approximately 7.
The principle flaw you'll find in quartzite is its tendency to etch in certain areas of countertops. Etching, or cutting and scratching into unprotected surfaces due to acid or other other substances, can be prevented by hone finished stone rather than polish finished. Honed countertops are not reflective, unlike polished, but it's more difficult to polish stone the harder it is. Because honed stone is smoother and flatter than polished, this can help prevent etching. While not as glossy as a polish surface finish, honed surfaces on harder materials are much more durable for quartzite kitchen countertops.When in need of a premium kitchen countertop, Marble and Granite can help give you the results you've always wanted.
