Engineered quartz countertop stone is manufactured from a mix of approximately 93% crushed natural stone (including quartz), a resin binder, pigments, and additives. The marriage between stone and resin is completed under intense heat and pressure. The end result is a non-porous material, a very nice attribute for a countertop surface. Engineered quartz stone slabs and countertops are available in a wide range of colors, patterns, and even textures. Unlike natural stone surfaces, man-made quartz has consistency of shade of colors and patterns with little variability. It is ideal for people who want uniformity in their countertops.
