For the finished finishing marble stone, its quality can be identified from the following four aspects:
One view, that is to observe the surface structure of stone. Generally speaking, uniform fine material structure of stone with exquisite texture, for the jiapin stone, coarse-grained and unequal-grained structure of the stone has a poor appearance. In addition, due to the impact of geological effects of stone often produce some small cracks, stone most easily along these parts of rupture, should pay attention to remove. As for the lack of angular impact is more beautiful, especially when choosing.
Two volumes, that is, the size of the stone specifications, so as not to affect splicing, or the mosaic after the pattern, pattern, line deformation, affect decorative effect.
Listen to the percussion sound of the stone. Generally speaking, the good quality stone its percussion sound is crisp and pleasing, on the contrary, if there is a slight fissure inside the stone or because the weathering causes the contact of the granule to become loose, then the percussion sound is gruff.
Four-Test, that is, using simple test methods to test the quality of stone. Usually on the back of the stone drops a small ink, such as ink quickly scattered around the leaching, that is, the stone internal particles loose or gaps, stone quality is not good.
