Gloss is an critical evaluation standard of the top quality of stone veneers. The gloss, on 1 hand, is dependent on the refractive index of the different minerals of the stone, and on the other hand, is carefully related to the micro-construction of the stone’s surface.
The exact same kind of granite stones has comparable mineral composition, so the smoother stone’s area, the larger gloss. The micro-structure of the stone’s area is dependent on the quality of grinding procedures. There are pits and streaks on the stone floor left by grinding procedures. Some of these pits and streaks are caused by its possess mineral flaws which can not be defeat in recent processing situations, some other people, nevertheless, are triggered by the mismatch of grinding resources utilized in the procedures.
To notice these very slight flaws, we can put an processed granite stone veneer against the sunlight or the fluorescent light, and notice its reflective area, and then a selection of pits and streaks can be located. The irregular modest pits might be triggered by the granite stone’s very own defects of its mineral composition, and can be ignored. Even so, if a amount of standard streaks are discovered on the surface of the granite stone, this must be because of to the poor diamond grinding quality. We should steer clear of this sort of granite stones when getting.
Granite veneers are usually ground with diamond cup wheels, which are a steel-bonded diamond grinding instrument. The dimensions (grit) of the diamonds on the cup wheel influences the area smoothness of the granite veneer. Even Kitchen countertops result in a rougher surface area, while more compact diamonds lead to a smoother end.
