Heat soaking for tempered glass is a process used to reduce the risk of spontaneous breakage in the glass.
Tempered glass is known for its strength and safety features, but it can still be susceptible to spontaneous breakage due to nickel sulfide inclusions. These inclusions are small particles that can cause the glass to break under certain conditions. Heat soaking involves placing the tempered glass panels in a specialized oven and heating them to a specific temperature for a set period of time. This process is designed to force any glass panels with nickel sulfide inclusions to break during the heat soak, rather than after installation. By identifying and removing these faulty panels before they are installed, heat soaking helps to minimize the risk of spontaneous breakage in tempered glass applications. This is particularly important in architectural and structural designs where the consequences of glass breakage can be severe.
Heat soaking is an important quality control step in the production of tempered glass, helping to ensure the safety and reliability of the final product.Heat soaking for tempered glass is a process used to reduce the risk of spontaneous breakage in the glass.

The self-explosion will be less than 0.3%.
One type of imperfection is nickel sulfide (NiS) inclusion. Most NiS inclusions are stable and don't cause any problems. There is, however, the potential for NiS inclusions that may cause spontaneous breakage in tempered glass without any load or thermal stress being applied.
Heat soaking is a process that may expose NiS inclusions in tempered glass. The process involves placing the tempered glass inside a chamber and raising the temperature to approximately 550°F or 287° to accelerate NiS expansion. This causes glass containing NiS inclusions to break in the heat soak chamber, thus reducing the risk of potential field breakage.
