A concept: visual observation of the surface structure of the stone. In general, uniform fine structure of stone materials with a delicate texture, the share of Stone; stone coarse grain structure and varying its poor appearance, mechanical properties are not uniform, slightly lower quality. In addition, natural stone due to the impact of geological, which often produce some fine pulsating, micro-cracks, the stone most likely to rupture along these areas, attention should be removed. As for the lack of edge angle is less aesthetic impact, particular attention should be selected.
Two amounts: the amount of stone sizes. So as not to affect splicing, or cause after stitching pattern, patterns, lines deformation, affecting the decorative effect.
Three: to listen to the stone percussion sounds. In general, good quality, and no internal dense uniform microfractures stone, its clear and melodious percussion; on the contrary, if the presence of microscopic cracks inside the stone or veinlets or indirectly due to weathering cause thixotropic loose particles, percussion sound gruff.
Four test: a simple test method to test the stone quality is good or bad. Usually in the back of the stone on a small drop of ink droplets, such as ink quickly disperse leaching, it means that the stone loose inside the particles or the presence of microscopic cracks, poor quality stone; conversely, if the ink droplet does not move in the same place, then Stone compact, good texture. In the selection of the finished sheet, as raw materials are natural stone, can not be exactly the same texture, in the mining, processing technology level there are differences. Most stones are graded on a scale, and many distributors also according to quality of. But a few do not distinguish, shoddy, deceive consumers. In order not to make mistakes, ordinary consumers in the decoration stone is best not-included, go to the city to buy building materials.
