Its melting point is 1300℃,temperature resistance is 300℃
Merarnorphic rocks, if the temperature is more than 650℃,it will decomposed
Stain resistance
Drop the soy sauce,vinegar,coffee on the quartz stone,and wipe it with it with detergent water after 24 hours,then observe if its surface color change or not.
Mainly made of calcium carbonate,the surface is more easily to be penetrated.
