Tempered glass manufacturing

The glazing process for tempered glass begins with a preparation stage that includes cutting the glass to the desired size and examining the glass for imperfections. Next, the glass is put through a heat treatment in which the glass is heated to 600 degrees Celsius. 

The heating treatment is followed by “quenching”, a high-pressure cooling procedure in which the glass is cooled in seconds. The quenching cools the outer surface of the glass more quickly than the center leaving the center in tension and the outer surface in compression, this is what gives tempered glass its strength.

The added endurance caused by the differential heating means the glass can be stretched or pulled to a certain limit without breaking.

Benefits of tempered glass

• Safety: Tempered glass reduces the risk of injury due to its nature of breaking into small, circular pieces instead of sharp, jagged shards.
• Easy clean up: Tempered glass isn’t indestructible. If the glass breaks it fractures into small fragments instead of large, jagged pieces.
• Strength: Tempered glass is incredibly durable.

Tempered glass application

 Tempered glass uses are varied and include doors, windows, partitions, handrails, stairs, facades, car windows, refrigerator shelves, cookwares and more. Tempered glass is best employed in situations where it might be necessary to break the glass in an emergency, such as on a fire extinguisher cabinet.
