What is Silestone Quartz Countertops

What is Quartz?

Quartz is one of the hardest minerals found in nature. It is highly abundant and makes up 12% of the earth’s crust. Quartz is extremely durable and resistant to scratches, heat and stains. These properties make it ideal for use in countertops.

Silestone uses ground quartz crystals combined with polyester resins and pigments to create an engineered stone that has the look and feel of natural stone but with enhanced performance. The quartz content gives Silestone surfaces hardness and strength while the resins ensure they are non-porous and resistant to scratches, stains and heat up to 650°F.

  • The mixture is compacted under vacuum conditions and vibration to remove air pockets.
  • It is then baked at high temperatures to cause the resins to harden into a uniform slab.
