Purchase of stone

The quality of finished finished facing stone can be identified from the following four aspects:

At a glance, the naked eye observes the surface structure of the stone. Generally speaking, stones with a uniform fine-grain structure have a delicate texture, which is a good product for stone; the appearance of coarse-grained and unequal-grained stone is poor. 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 crack along these parts, and should be removed. As for the lack of edges and corners, it also affects the appearance, especially when choosing.

The second quantity is the size of the stone, so as not to affect the splicing, or cause deformation of the stitched patterns, patterns and lines, and affect the decorative effect.

Three listens, that is, to listen to the knocking sound of stone. Generally speaking, the knocking sound of good quality stone is crisp and pleasant; on the contrary, if there is a slight crack in the stone or the contact between the particles becomes loose due to weathering, the knocking sound is rough. 

Four tests, that is, a simple test method to check the quality of stone. Usually a small particle of ink is dripped on the back of the stone. If the ink is scattered and leached around quickly, it means that the particles inside the stone are loose or there are gaps, and the quality of the stone is not good. On the contrary, if the ink does not move in place, it means that the stone texture is good.
