Heat Soaking is a heating process carried out subsequent to toughening, when specified, to detect and reject any toughened glass that may have inclusions (Nickel Sulphate) or edge defects that may cause spontaneous breakages after installation.
Heat Soaked Glass FUSO Heat Soaked Glass can be used in critical application areas to eliminate the risk of spontaneous breakage. Nickel Sulphate (NiS) has been known to be the cause of spontaneous burst in Tempered Glass / Toughened Glass. During tempering the invisible nickel sulphide present in the glass is transformed to the high tempered a- phase (t>380C) has no time to retun to the ß- phase on quenching. With the passage of time NiS slowly inverts to the low temperature ß- phase with the increase in volume of about 4%. This volume expansion may cause glass breakage. The heat soak is a destructive treatment which heat the glass for several hours at about 290 degree C to speed up the a -NiS to ß - NiS transformation and consequently forces the contaminated glassess broken within the oven. Precautions Heat Soaked Testing is not an absolute guarantee that the glass will not break spontaneously due to NiS but it substaintially lowers the risk. Studies have been concluded worldwide indicating the reliability of heat soak test to as high as 98.5%.
