By combining nature and science we get an engineered stone known as Quartz. Quartz countertops are made from 93% Quartz crystals and 7% resin binder.  Quartz is one of nature’s hardest materials which makes these countertops very durable.  Quartz is non-pourus preventing unwelcome germs, mildew, and bacteria. It is very easy to maintain Quartz- all you need to do is wipe it down with warm water. No sealing necessary.  Quartz countertops have been certified by the National Sanitation for Food Safety and Food Contact under NSF 51 Certification. These countertops can be found in restaurants, healthcare facilities, office buildings, and homes.  The average cost for Quartz kitchen countertops is between $3000 and $4500 dollars.
