Gloss is an crucial evaluation common of the high quality of stone veneers. The gloss, on one hand, depends on the refractive index of the numerous minerals of the stone, and on the other hand, is closely relevant to the micro-composition of the stone’s surface area.
The very same sort of granite stones has similar mineral composition, so the smoother stone’s surface area, the higher gloss. The micro-composition of the stone’s surface depends on the top quality of grinding processes. There are pits and streaks on the stone floor left by grinding processes. Some of these pits and streaks are caused by its very own mineral problems which can not be overcome in existing processing circumstances, some other folks, nevertheless, are caused by the mismatch of grinding equipment used in the processes.
To notice these very small flaws, we can set an processed granite stone veneer against the sunlight or the fluorescent light, and observe its reflective area, and then a assortment of pits and streaks can be discovered. The irregular small pits may possibly be induced by the granite stone’s personal defects of its mineral composition, and can be disregarded. However, if a number of standard streaks are located on the surface of the granite stone, this ought to be thanks to the inadequate diamond grinding good quality. Kitchen countertops need to stay away from this type of granite stones when acquiring.
Granite veneers are typically ground with diamond cup wheels, which are a metal-bonded diamond grinding tool. The dimension (grit) of the diamonds on the cup wheel influences the surface smoothness of the granite veneer. Greater diamonds result in a rougher surface area, although smaller diamonds lead to a smoother end.
