Scratch-resistance-Bienstone quartz is hard enough to be good mar-proof,not any damage caused even by iron object.(But diamonds, sand paper, Kentanium are not allowed to contact on the surface. Anti-stain-Bienstone quartz is made of complex materials and fine quartz, which guarantees low water absorption rate in 0.***0.*4%,High density makes outstanding stain-resistance. Burn-proof*-Bienstone quartz melting points is at ***0 degree and it is good fire proof because of special quartz composition. Corrosion resistant-Bienstone quartz can bear any normal chemicals, Ageing resistance-Bienstone quartz contains anti-UV agent to retard ageing effectively. Good fastness-Bienstone quartz uses mineral pigments to anti-UV causing fading.
