How to identify the quality of Mongolian Black Granite?

Mongolian black is more and more widely used in decoration engineering. For the processed finished Mongolian black stone, its quality can be identified from the following four aspects:

On the one hand, the surface structure of Mongolian black stone is observed by naked eyes. Generally speaking, the stone with uniform fine material structure has a fine texture, which is the best stone; the appearance effect of the stone with coarse-grained and unequal grain structure is poor. Besides, due to the influence of the geological process, stone often produces some minor cracks, which are most likely to crack along these parts, so it should be removed. As for the lack of edges and corners, which affects the beauty, we should pay special attention to it when choosing.

Second, measure the size and specification of the stone to avoid affecting the splicing, or causing the deformation of the pattern, pattern, and line after splicing and affecting the decoration effect. (for this point, Mongolian black stone generally does not have the problem of poor design and color.)

Third, listen, that is, listen to the sound of stone percussion. 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 particles becomes loose due to weathering, the knocking sound is coarse and dumb.

The last tips is tests, which is to use a simple test method to test the quality of the stone. Generally, a small particle of ink is dripped on the back of the stone. If the ink is quickly dispersed and leached around, it means that the particles inside the stone are loose or there is a gap, and the quality of the stone is not good; otherwise, if the ink drips in place, it means that the quality of the stone is good.
