As one of the hardest materials on Earth, quartz is used to manufacture engineered stone products with an esthetic appearance through technological processes such as the vibro compression vacuum process. Quartz stones contain quartz and other materials such as colored glass, metal, shells, epoxy, and polymer resin (an adhesive).Quartz stones have plain colors and symmetrical figures. They do not contain microscopic pores or hairline cracks, or scratches, as they are manufactured through vibro compression technology.Quartz stones have unique durability. They are the best alternatives to granites. Having 7 Mohs (scale of mineral hardness), quartz has a high hardness value. That hardness makes quartz durable to wear and scratches. Quartz is also durable with acidic liquids such as olive oil, vinegar, lemon, and wine. Countertops are easy to be cleaned. They do not need to have maintenance and polishing.
