Uncover how its distinctive manufacturing process influences strength and reveals potential weaknesses. Empower yourself with knowledge about tempered glass to make safer, more durable choices for your projects. Delve into our full article for a deeper understanding!
The Weakest Part of Tempered Glass-Corners and Edges.
The weakest parts of tempered glass are the corners and edges. The middle part of tempered glass is the strongest part, while the corners and edges are the weakest parts. This is because tempered glass improves its strength by forming compressive stress on the glass surface, and stress concentration is prone to occur at the corners, making these parts relatively fragile.

Tempered glass, also known as toughened glass, is a form of safety glass that has been treated through controlled processes of thermal or chemical heat to increase its strength compared to normal glass. This specially treated glass is known for its enhanced durability and resistance to impact, thermal stress, and shattering, making it an ideal choice for various applications ranging from architecture to automotive design.
Tempering Processing of Tempered Glass:
Heating: The cleaned glass is then gradually heated in an oven to temperatures ranging from 600°F to 1,000°F (315°C to 540°C). This process may take several minutes, and it is crucial that the heating is even to avoid creating weak points in the glass.
Cooling (Quenching): After achieving the desired temperature, the glass is rapidly cooled using high-velocity air jets. This rapid cooling process, known as quenching, causes the outer surface of the glass to cool and contract faster than the inner layer, creating a state of internal tension that enhances its strength.
Advantages of Tempered Glass
High strength: Bending strength and impact strength of tempered glass are 3-5 times that of ordinary glass
High safety: if tempered glass breaks, it shatters into small obtuse-angled particles, reducing harm to the human body
Good thermal stability: tempered glass is able to withstand large temperature differences, such as 300°C temperature differences.
Disadvantages of Tempered Glass:
Tempered Glass Cannot be reprocessed: Tempered glass cannot be cut or reprocessed, after being tempered, the tempered glass should be cut into required size and drilled before tempering process.
Tempered Glass Has Possibility of Self-Destruction: Tempered Glass May self-destruct when there is no external effect, the self-destruction rate is 0.3%-3%
Tempered Glass Has Uneven surface: The tempering process may cause uneven surface on the tempered glass sheets.
So when we are using tempered glass products, try to protect their corners and edges to prevent the breakage of tempered glass sheets. if you have other questions about tempered glass, contact us.
