      4 After heating the glass-type furnace temperature is too high, the temperature between inner and outer layers is large different, inner tension is too large. Appropriate to reduce the furnace temperature, prolonged heating time.
     
      5 The glass drilling edge does not deal with good or glass drilling diameter is smaller than the thickness of the glass. Handle drilling edge, increasing the diameter of the glass drilling.
