Toughened Glass can sometimes spontaneously break; the reasons can be many. The main cause determined by leading experts are that there are microscopic traces of Nickel Sulphide (NiS) inclusions within the glass which can be activated during the heating process in producing tempered glass.
At Tough Glass the heat soak treatment is a quality control process carried out by placing the toughened glass panels inside an oven chamber and subject the glass to a prolonged temperature up to 290 degrees Celsius in a controlled cycle to accelerate nickel sulphide expansion. This causes glasses containing nickel sulphide inclusions to break in the heat soak chamber, thus reducing the risk of potential breakages after installation.
