How Do You Select Good Granite Stone Veneers?
Gloss is an important evaluation standard of the quality of stone veneers. The gloss, on one hand, depends on the refractive index of the various minerals of the stone, and on the other hand, is closely related to the micro-structure of the stone’s surface. The same kind of granite stones has similar mineral composition, so the smoother stone’s surface, the higher gloss. The micro-structure of the stone’s surface depends on the quality of grinding processes. So when purchasing granite stone, the identification of the grinding quality is essential. If we do not acquire some skills, the identification work will be very difficult. There are pits and streaks on the stone surface left by grinding processes. Some of these pits and streaks are caused by its own mineral defects which can not be overcome in current processing conditions, some other, however, are caused by the mismatch of the thickness of grinding tools used in the processes. To observe these very minor defects, we need to be ve
