1. Test the hardness method: We can scrape the Compound Quartz Stone with a hard object such as a knife or a nail clipper. The high-quality quartz stone plate will not be scratched, and the knife or nail clipper will be left on the surface of the quartz stone plate. Iron filings. Use a damp cloth or hand to remove iron filings. The surface of the quartz stone plate is intact. Reason: The surface hardness of high-quality quartz stone plate is as high as Mohs hardness of 6-7, which is much larger than the tool used by people for daily use.

    2. Test the high-temperature resistance method: We can directly burn the surface of the Composite Quartz Stone Countertops with the cigarette butt, but the cigarette butts will not leave any trace on the high-quality quartz stone surface. Reason: High-quality quartz stone plate contains 93% of high-quality quartz crystal substrate and high-quality supplementary filler to make it have high-temperature resistance.

    3. Test the corrosion resistance method: use any ratio of hydrochloric acid (or sulfuric acid) to drop on the surface of the Composite Quartz Stone Surface, and the high-quality quartz stone plate has no reaction. Reason: High-quality quartz stone plate is made of high-quality natural quartz except for a small amount of resin and additives. It has strong acid and alkali resistance. Acids and bases often encountered in life are even less likely to cause damage.

    4. Test quartz content method: ignite quartz stone with flame, high-quality quartz stone plate is not easy to ignite. If thrown in a giant heat flame for full combustion, the high-quality quartz stone can still maintain the original shape of the quartz stone plate. Reason: High-quality quartz stone is basically a selection of imported high-grade materials.
