Do you know the quartz stone’s performance?

1.scratch resistance, contain quartz about 94%.quartz crystal hardness is only lower than diamond in the natural minerals.Quartz stone hardness is about 7.5 mohs, greater than the kitchen knife shovels, etc, so the quartz stone countertop is hard to be scratched.
2.anti-pollution Quartz stone is dense non-porous composite material made under vacuum conditions, quartz stone countertop is excellent corrosion resistance, daily use liquid substance will not penetrate, long time liquid ponding can be erased by rag.
3, durable: quartz stone had been polishedthrough multi-channel, will not be scratched byshovel and knife, non penetrate, won't yellowing and discoloration, simple and feasible maintenance.
4. anti-flamethe natural quartz crystal is a typical refractory material, its melting point is 1300 degrees, quartz stone is made of 94% quartz crystal, flame retardant, completely will not burn  because of high temperature combustion
5.non-toxic, no radiation Quartz stone is smooth, no scratches stranded, dense non-porous makes the bacteria nowhere to hide, can direct contact with food, it is safe and non-toxic.
