Composite quartz countertops, like granite, are some of the most durable and beautiful materials in the solid surfaces industry today. These types of custom stones are man-made, comprised of 93% to 97% natural quartz, which is one of the hardest materials in the earth. Composite quartz surfaces are also known as engineered granite. These products are stain resistant, durable, resilient and color consistent. The general process is natural quartz crystals are ground into an aggregate or fine powder after being mined. This quartz dust is then added to a binder made of resin. This process takes place under intense pressure and heat to form a stable, solid slab. During this phase coloration is added to develop that final product into the color desired. These pigments are solid and are permanent so they won’t fade or change over time.
