Quartz (sometimes called Engineered Stone) is a man-made slab made of 93% quartz and 7% resin to create a stone look-alike with tremendous hardness, strength and durability. The mixture of various sizes and colors of mined quartz are mixed with advanced polymer resins and a small amount of color is placed in a mold and compressed under 100 tonnes of pressure. This eliminates any voids to create a totally non-porous surface that is then milled and polished in a typical slab format.
The advantages of quartz include strength, durability, extremely stain resistant with easy clean up with soap and water and never needs a sealer. All quartz manufacturers also provide a warranty of at least 10 years. NSF certifies all quartz products for use in food preparation areas. The price is highly competitive with natural stone.
