More about Historical: Engineered Stone (Quartz Countertops) - 2016
Engineered stone slabs offer an alternative to quarried stone which can be expensive, limited in available dimensions, and difficult to color match. Engineered stone is made by combining granules of particulates - often quartz-containing rocks and minerals, but also glass, seashells, or other materials - with a polyester resin, and pressing the mixture into a slab under high heat and a vacuum. This process is known in the industry as Bretonstone. The slabs can be cut to size for use primarily as countertops, but also for flooring or other interior applications. Where quarried stone contains pores that requires the product be regularly sealed, engineered stone is non-porous so resists staining. Because they are frequently used surfaces, and may be near food, there is increasing attention about the growth of microbes on countertops. At least one major manufacturer of engineered stone promotes its use of the biocide triclosan, however due to a lack of disclosure about antimicrobials added to products for preservation purposes, it is not known at this time whether the inclusion of biocides in engineered stone is common. This CP therefore does not include a biocide.
