What can I do to reduce chipping at the edge of the glass – it happens in the furnace.

In our experience, the most typical reason for edge chipping in the tempering process is that glass is bending during the heating process, so that the edges are bending down. Then those edges are hitting the rollers while oscillating. Impact on the roller causes the chipping at the edge. To reduce or avoid the chipping, try to keep the glass flat during the heating. This can be done by balancing the heat transfer between top and bottom with top/bottom convection or heating.

As always, remember to learn, share and succeed!
