Teach you how to distinguish the quality of stone
A visual observation of the surface structure of the stone
In general, 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 of the stone have a poor appearance. In addition, due to the influence of geological effects, the stone often produces some fine cracks in it. 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.
Dimensional specifications for two-volume stone
So as not to affect the splicing, or cause the pattern, pattern, and line deformation after splicing, affecting the decorative effect.
Three listen to the tapping sound of the stone
In general, the sound of a good quality stone is crisp and pleasing; on the contrary, if there is a slight crack inside the stone or the contact between the particles becomes loose due to weathering, the knocking sound is rough.
4. Try a simple test method to check the quality of the 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.
