Why is heat soaking done in toughened glass? – Nova Glass Tech Explains

Heat soaking is a crucial process performed on toughened glass to reduce the risk of spontaneous breakage caused by nickel sulfide (NiS) inclusions. At Nova Glass Tech, we ensure that our heat soaked toughened glass meets the highest safety and performance standards for architectural, commercial, and high-rise applications.

When glass is toughened, microscopic nickel sulfide particles present in the raw material can become unstable. These NiS inclusions may not be visible but can later expand slowly over time—especially under heat or pressure—causing sudden and dangerous glass breakage, often without warning.

The heat soaking process involves placing toughened glass panels in a controlled oven and gradually heating them to around 290°C to 300°C for several hours. This accelerated thermal cycling forces any NiS inclusions to expand and potentially break the affected glass during the test phase itself—in the factory, not on-site.

By performing heat soaking, Nova Glass Tech ensures:

• Greater safety and reliability

• Compliance with international safety standards like EN 14179

• Peace of mind for builders, architects, and end users

Heat soaked toughened glass is ideal for skylights, façades, railings, curtain walls, and other high-risk applications where human safety and structural reliability are non-negotiable.
