Quartz is a chemical compound consisting of one part silicon and two parts oxygen (silicon dioxide). Its unique properties make it one of the most useful natural substances. Quartz for surfaces is engineered, by combining up to 93% Crushed Natural Quartz and 7% Resin. This makes the stone just as strong as granite, but slightly heavier.
Durability:
Resistant and durable like granite, but does not withstand prolonged exposure to really high temperatures, not for outside kitchens. (engineered & hard)
