When the same kind of pavement in the same plane as the larger particular should pay attention. Stone occurred color have several reasons: First stone blocks taken from the mine layer, not the same level from the pit or not the same; stone processing in the back yard did not follow the blocks of numbers and batches; when the stone pavement did not follow the code supplied single supplier and lot number and so on. Because ore reserves and the reason, the color problem in detail the extent of reaction is not the same kind of stone, and some types of nearly 1,000 square meters of stone or ten thousand square meters will not be a problem, but some kind of a few hundred meters on not be guaranteed. Here the choice of stone will begin to take into account such problems. 2, a good product for processing decorative stone, its quality how to identify? A concept that visually observed surface structure of stone. In general, uniform fine structure of stone material with a delicate texture, is to share the stone. Stone ranging from coarse grain structure and its appearance is poor. In addition, due to the influence of geological stone in which often produce some minor cracks in the stone along these areas most prone to rupture, it should be noted removed. As for the lack of impact is more angular appearance, particular attention should be selected. Second, the amount that the amount of stone sizes, so as not to affect splicing, or cause after stitching pattern, patterns, lines deformation, affecting the decorative effect. Three, namely listening stone percussion sounds. In general, a good quality stone percussion its clear and melodious.
