Quartz countertops are a form of engineered stone made from ground-up particles of quartz bound together with resins.
Quartz countertops have certain qualities that make them special, even among other stone countertops like granite. You can find quartz countertops in many colors-from bright whites to cool grays, warm creams, and rich browns and blacks. Some quartz has veining that makes it look like marble. And some options contain mirror chips that reflect light and appear to make the countertops sparkle.
Their primary ingredient is ground quartz (about 94 percent), combined with polyester resins to bind it and pigments to give it color. For some designs, small amounts of recycled glass or metallic flecks are added to the mix. The resins also help make these counters stain and scratch resistant-and nonporous, so they never need to be sealed. Compare that with granite, the reigning king of high-end countertops, which typically requires a new protective top coat at least once a year.
