When the temperature of the glass inner and outer layers are lower than the Tg (glass transition temperature), we believe that steel and glass phase is complete, you can cool down on the glass. Cooling rate and final temperature of the glass depending on the production cycle, so as not to form excessive stress and convenient temporary artificial showings prevail.

In the production of large thickness of the glass, the glass cooling rate of the general requirements appropriate to reduce, avoid the formation of excessive stress caused temporarily broken glass. Usually in the production of thin glass, the cooling air pressure is always constant; in the production of thick glass, the first cooling air pressure set point is always low, and then gradually increase, in order to obtain a faster production cycle.
