China is rich in mineral resources and rich in granite and marble deposits. The following is a brief introduction to the quality of the finished finished marble stone. The quality of the marble Headstone can be identified from the following four aspects.
One view, that is, the surface structure of the marble stone is observed by the naked eye. In general, the coarse-grained and unequal-grained stone has a poor appearance, and the uniform fine-grained stone has a delicate texture and is a good stone. In addition, due to the influence of geological effects, the stone often produces some fine cracks in it, and the stone is most likely to rupture along these parts, and should be removed. As for the lack of edges and corners, it is more important to affect the appearance, especially when choosing. Especially in summer, too high temperatures will have a certain impact on the stone.
The second quantity, that is, the size specification of the marble stone, so as not to affect the splicing, or cause the pattern, pattern and line deformation after splicing, affecting the decorative effect.
Three listening, that is, listening to the sound of stone marble. In general, if the stone is not well-punched, there is a slight crack in the interior or the contact between the particles becomes loose due to weathering. On the contrary, the stone of good quality is crisp and pleasant.
Four tests, that is, using a simple test method to test the quality of marble stone. Usually a small amount of ink is dropped on the back side of the stone. If the ink is quickly dispersed and leached everywhere, it means that the inside of the stone is loose or there is a gap, and the quality of the stone is not good. Conversely, if the ink is not moved in place, the stone material is good.
