Comprised mainly of quartz, Rongguan Engineered Quartz is hard and condense, it is
superficial hardness is very high(mohs hardness:6-7), is resistant to scratch, wear,

shock, rupture and compression, and have excellent heat resistance, corrosion 
resistance, and stain resistance, which are advanced to artificial Marble(Shanxi Black). Not being

distorted, split, and being resistant to discoloration, fading. It is durable and

maintenance free. Furthermore, it does not contain any pollution and radiation, thus
is an environmental friendly building material
