Method of selecting and buying high quality stone
One view, that is, the surface structure of the stone is observed by the naked eye. Generally speaking, the stone material with uniform fine material has a fine texture and is a good material for stone. The appearance of coarse grain and unequal grain structure is poor. In addition, the stone because of the effect of geological effects often produce some fine cracks, the stone is most easily broken along these parts, should be removed. The angle of lack of edges is more beautiful, especially when choosing.
Two, that is, the size of the size of the stone, so as not to affect the splicing, or to cause the pattern, pattern, and line deformation after the splicing, and affect the decorative effect.
Three listen, that is, to listen to the sound of the stone. Generally speaking, the hammering sound of good quality stones is crisp and pleasant. On the contrary, if there is a slight crack inside the stone or the contact between particles becomes loose due to weathering, the knocking will be rough.
The four test is to test the quality of the stone by a simple test method. Usually, a small amount of ink is dripped on the back of the stone, such as the ink dispersing quickly, indicating that the particles inside the stone are loose or crevice, and the quality of the stone is not good. Conversely, if the ink drops do not move in situ, it indicates that the stone quality is good.
