How To Distinguish High Quality Natural Stone

As natural stone is used more and more in people’s lives, how to distinguish the quality of stone?

The first step: observation. That is, the surface structure of the stone is observed by the naked eye. Generally speaking, the uniform fine material structure of the stone has a delicate texture, which is a good stone; the coarse grain and the unequal grain structure stone have poor appearance effect, the mechanical properties are not uniform, and the quality is slightly poor. In addition, due to the influence of geological effects in natural stone, some fine veins and micro-cracks are often produced in it, and the stone is most likely to rupture along these parts, and should be removed. For the stone with less corners and less angles, it is more beautiful, and you should pay attention to it when choosing.

The second step: measurement. That is to measure the size specifications of the stone. In order to avoid affecting the splicing or causing the pattern, pattern and line deformation after splicing, affecting the decorative effect.

The third step: listening to the sound. That is to listen to the sound of the stone. Generally speaking, the stone with good quality, uniform internal density and no micro-cracking is crisp and pleasant; if there is micro-crack or fine vein inside the stone, or the contact between the particles becomes loose due to weathering, tapping The voice is hoarse.

The fourth step: testing. That is to use a simple test method to verify the quality of the stone is good or bad. For example, a small drop of ink is dropped on the back side of the stone. If the ink is quickly dispersed and leached everywhere, it means that the internal particles of the stone are loose or there are micro-cracks, and the quality of the stone is not good; otherwise, the stone is dense and the texture is good.
