Quartzite

Quartzite is a natural stone.  Quartzite begins with sandstone, which under the natural process of heat and presure causes the stone to form quartz crystals.  It can often be mistaken with marble or granite due to the colors and patterns.  However quartzite is very porous, and requires sealers to protect the stone.  It easily stains, so if you spill something on quartzite you will need to quickly clean it off.
