How to check marble surface finish quality?
Polishing glossy is a important inspection standard in stone polishing. For glossy checking, two main inspection is done, one is done visually and the other is done by glossy meter.
For visual inspection, inspector uses lights to check stone surface finish. Take a vertical view, back lighting view and front lighting view to check stone surface with lights flashes on different location to see if the polishing is clear, with or without marking or circles.
For glossy meter inspection. Inspector will check 9 different locations on edges and center of stone pieces and average the inspection value to get the final glossy. It is because stone is with different rock formation which may have different index of refraction, so it is not a correct method to check just one or two locations of stone pieces.
