Gloss is an critical analysis regular of the high quality of stone veneers. The gloss, on 1 hand, relies upon on the refractive index of the various minerals of the stone, and on the other hand, is carefully connected to the micro-composition of the stone’s surface area.
The identical sort of granite stones has equivalent mineral composition, so the smoother stone’s surface, the larger gloss. The micro-construction of the stone’s floor is dependent on the quality of grinding procedures. There are pits and streaks on the stone surface area remaining by grinding processes. Some of these pits and streaks are caused by its possess mineral problems which can not be get over in present processing problems, some others, even so, are triggered by the mismatch of grinding resources used in the procedures.
To observe these very small flaws, we can place an processed granite stone veneer from the sunlight or the fluorescent gentle, and observe its reflective surface, and then a variety of pits and streaks can be discovered. The irregular tiny pits may possibly be brought on by the granite stone’s possess flaws of its mineral composition, and can be disregarded. Nevertheless, if a number of standard streaks are found on the floor of the granite stone, this ought to be thanks to the very poor diamond grinding high quality. We need to steer clear of this sort of granite stones when buying.
Granite veneers are typically ground with diamond cup wheels, which are a metallic-bonded diamond grinding instrument. The measurement (grit) of the diamonds on the cup wheel influences the floor smoothness of the granite veneer. Kitchen countertops lead to a rougher surface, although more compact diamonds direct to a smoother complete.
