Enlarge the schematic. 3 and FIG. 4, after the etching by an etching medium such as hydrofluoric acid (HF), the micro-cracks on the cutting section of FIG. 3 are etched into arcs or teeth of the one shown in FIG. The groove 44, that is, the original sharp spiked crack becomes a gentle and large groove, so that when the glass is bent or flexed, the possibility of cracking inward from the edge can be greatly reduced, and the glass is greatly increased.
