고온 내성

Its melting point is 1300℃,temperature resistance is 300 ℃.

Metamorphic 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 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.

Fire resistance

Put the quartz stone in size 10 mm × 30 mm on the open fire, the strip can’t burn.

Marble is a kind of incombustible materials.

Acid and Alkali Resistance

Erode the quartz stone surface with 3% hydrochloric acid solution, etc. And no visible change at the quartz stone surface.

There would be chemical reaction between marble and acid solutions. It is easier to be eroded.
