Glass annealing process

Jolee Sunny Glassware 2018-10-15 18:26:46


Glass annealing process


Annealing is to keep warm or slowly cool for a period of time to eliminate or reduce the thermal stress in the glass to an allowable value.The temperature is generally 480 degrees to 540 degrees.


Why need annealing
The glass undergoes intense temperature changes and shape changes during the forming process, which leave thermal stress in the glass. This thermal stress reduces the strength and thermal stability of the glass article. If it is directly cooled, it is likely to break itself during storage, transportation and use during cooling or later (commonly known as cold explosion of glass). In order to eliminate the cold explosion phenomenon, the glass article must be annealed after forming.
