Question: what is the difference between granite quartz and marble countertops?
Answer: Quartz is a mineral, while marble and granite are rocks. ... Quartz is the main ingredient in the engineered stone use to make countertops and backsplashes. Powdered quartz is mixed with a resin and then formed into slabs. Because of this, engineered quartz stone doesn't need to be sealed, as does porous granite or marble.
