Annealing is a process employed when double glazed units are manufacturered. The glass panel is heated in such a way so that the entire pane has a uniform temperature. The temperature is then held steady for long enough to remove all internal stresses introduced by the formation of the glass while it was in it's molten state. The glass is then slowly cooled. This process has several benefits for the glass. If the stresses are not removed, this can cause fractures later on from slight impacts, or sizeable changes to temperature. The optical properties of the glass are also improved.
