Heat soaking treatment is a quality control process where tempered glass panels are placed into an oven and exposed to controlled cycles, subjecting the glass to temperatures as high as 290 degrees Celsius to accelerate the expansion of nickel sulfide. Consequently, glass containing nickel sulfide inclusions is more prone to breakage within the heat soaking chamber, thereby reducing the risk of breakage post-installation. It’s important to note that the heat soaking process does not guarantee that tempered glass panels treated in this manner will not experience spontaneous breakage in the future. This service acts as an additional measure to help prevent potential spontaneous breakage down the line.
