Natural stone quality identification

The quality of natural stone can be identified from the following aspects:

One view: The surface structure of natural stone is observed with the naked eye. In general, a uniform fine stone material has a delicate texture and is a natural stone; coarse and unequal grain stones have poor appearance, mechanical mechanical properties are not uniform, and the quality is somewhat poor. In addition, due to the geological effects of natural stone often produce some small cracks in it, natural stone is most likely to break along these parts, should be removed. The lack of edges and corners is even more aesthetically pleasing, especially when choosing.

Listening: Listen to the natural stone's percussion sound. In general, a good quality natural stone sounds crisp and melodious; on the contrary, if there is a microscopic crack inside the natural stone or the particles become loose due to weathering, the knocking sound is rough and dumb.

Three tests: Use simple test methods to test the quality of natural stone. Usually, a small amount of ink is dripped on the back of natural stone. If the ink quickly spreads out and leaches out, it indicates that the particles inside the natural stone are loose or there are gaps. The quality of the stone is not good. On the contrary, if the ink drops are not moving, it means that the stone is dense. Good texture (this is similar to ceramic tiles).
