2. Thin skin bubbles that are ruptured by nails or pins are not allowed to exist;
3, small bubbles of diameter <0.8mm, no more than 3 in the range of 20mm * 20mm, and the spacing is greater than 50mm, no more than 5 on each product, if necessary, seal the sample.
Second, the stone

2, protruding surface, and the sharp nails of the stone are not allowed to exist;
3. Stones with cracks around are not allowed to exist.
Third, the crack

Draw sharply with sharp objects, a linear wear formed on the surface of the glass, visible scratches under the inspection lamp, and not allowed to exist.
Five, sticky glass
