In addition to the high requirements for the firmness and environmental protection of the marble countertops, the radioactivity of the stone is also strictly controlled. For a long time, people have mistakenly thought that marble countertops will have radiation, and they will inevitably have some concerns when buying. In fact, the radioactivity of natural marble countertops is very low, which basically does not cause harm to the human body. It is not easy to be corroded by oil and is convenient for cleaning.
There are several rules to distinguish the pros and cons of marble countertops:
First: Visually observe that the color of the sample is pure and not turbid, the surface has no plastic-like texture, and there are no small pores on the back of the plate.
Second: No pungent chemical smell in the nose.
Third: The sample surface has a silky feel, no astringency, and no obvious unevenness.
Fourth: Scratch the surface of the board with a nail without obvious scratches.
Fifth: The same two samples are knocked against each other and are not easily broken.
