Hello! Just curious. With my plate glass blank, I have to be VERY careful in removing the glass from the tile tool when I get to 15 and 9 micron WAO. With the surface tension, I had to slide the mirror about 1/2 to 2/3 to the side to break contact with constant upward pressure on the edges. A couple of times, I let the blank rebound back to the tool and it hit the tile (softly, I think), but I ended up with light scratches that took additional time to grind out.
Is Borofloat33 more scratch resistant than plate glass? The product info says strength is 2x more than plate glass; however, I'm not sure if this translates to scratch resistance. Best regards.
