Quartz countertops, also referred to as engineered stone, mix a high percentage of filler with a small amount of resin to achieve a countertop that mimics natural quarried stone with lower cost and maintenance. The primary manufacturing process, known in the industry as Bretonstone, uses high heat and vibrocompression to create a uniform slab. The slabs can be cut to size for use primarily as countertops, but also for flooring or other interior applications. Though quartz is most common, various fillers may be used including quartz-containing rocks and minerals, granite, glass, seashells and other natural stones. Quarried products may have variable composition depending on the source location. Recycled content, particularly recycled glass or mirrors, may also be used as fillers. The resin is most often a polyester resin. Various pigments are used to create a range of aesthetics. Those used to create white, black, and red colors are commonly listed and therefore included here, though many pigments may be used and each carries its own associated health hazards.
