Select stone first look at the surface and then look at the texture

The quality of stone depends on the quality of raw materials and processing technology. High-quality stone surface, does not contain too much miscellaneous color, uniform cloth color, no obvious light and dark transition situation, and quality stone after processing there will be a lot of irreparable "defects", so the stone surface pattern tone is an important indicator to evaluate the quality of stone. If the processing technology and process are not passed, the finished product after processing will appear warping, depression, color spots, stains, missing edges off corners, cracks, color lines, pits and other phenomena, such stone belong to "defective products".

Under normal circumstances, good stone should have such characteristics: smooth surface, no rough feeling when touched by hand; The front is bright, the reflective effect is consistent when facing the light observation, there is no flickering phenomenon; The cutting edge is smooth, and the cutting edge shows a straight line without serrated convex and concave points. The color is uniform, and the surface of each stone has no color difference; The texture is clear, the texture of the same type of stone is consistent, and there is no obvious difference.

When you buy can listen to the sound of stone tapping, generally good quality stone its tapping sound is crisp and pleasant, if there are slight cracks in the stone or due to weathering caused by the contact between particles become loose, then the knocking sound is rough, which indicates that the quality of stone is poor. When purchasing, it is also necessary to measure the size of the stone, so as not to affect the splicing, or cause the pattern, pattern, line deformation after splicing, affecting the decorative effect.
