Quartz has made a large splash in the world of solid slab counters. It is completely non-porous and never has to be sealed, unlike granite or marble. It is more scratch- and chip-resistant, and has heat resistance on par with stone. It is comprised of quartz crystals (normally 70-90%) and man-made binders, and formed and compressed in a high pressure process.
Styles can range from granite-like granular looks to nearly solid colors. The newest styles even mimic the highly random, cloudy and veined look of marble. Cost is typically similar to granite slabs, running $75 to $100 per square foot for materials and labor, depending on the brand and variables like edge treatment or specialty shapes.
