thumb|Quartzite can have a grainy, glassy, sandpaper-like surface
Quartzite is a hard, non-foliated metamorphic rock that forms when sandstone is subjected to heat and pressure deep within the Earth. It's valued for construction and industrial uses because of its durability and resistance to weathering, and it often has a distinctive grainy or glassy surface texture.
