Gloss is an essential evaluation common of the high quality of stone veneers. The gloss, on a single hand, depends on the refractive index of the a variety of minerals of the stone, and on the other hand, is intently associated to the micro-structure of the stone’s surface area.
The identical type of granite stones has comparable mineral composition, so the smoother stone’s surface, the larger gloss. The micro-composition of the stone’s floor depends on the good quality of grinding processes. There are pits and streaks on the stone surface left by grinding processes. Some of these pits and streaks are caused by its personal mineral problems which can not be defeat in existing processing conditions, some other people, even so, are triggered by the mismatch of grinding tools utilised in the processes.
To observe these really slight flaws, we can put an processed granite stone veneer against the sunlight or the fluorescent gentle, and observe its reflective floor, and then a range of pits and streaks can be located. The irregular modest pits might be induced by the granite stone’s possess flaws of its mineral composition, and can be disregarded. Nevertheless, if a quantity of typical streaks are located on the surface area of the granite stone, this ought to be owing to the inadequate diamond grinding high quality. We need to keep away from this type of granite stones when purchasing.
Granite veneers are typically ground with diamond cup wheels, which are a steel-bonded diamond grinding resource. The dimensions (grit) of the diamonds on the cup wheel influences the surface smoothness of the granite veneer. black marble countertops result in a rougher surface, while smaller sized diamonds direct to a smoother end.
