Heat soaked glass is when toughened glass is reheated and is slowly cooled. The reason for doing this is in toughened glass, there is a small risk of a nickel sulphide crystal naturally occurring in the glass during processing. The nickel sulphide crystal has a different expansion rate to glass so as glass heats and cools through the seasons, a spontaneous breakage may occur. This can be very costly if the glass is not easy to access post-installation. By heat soaking the glass, this risk is drastically reduced and if a breakage happens in the factory during processing, another panel can be produced.
