# Tempered Glass: Strength and Safety
Tempered glass is a type of safety glass that undergoes a specialized heat treatment to increase its strength and durability. It is up to five times stronger than regular glass and is designed to shatter into small, blunt pieces instead of sharp shards, reducing the risk of injury.
## How It’s Made
Tempered glass is produced by heating standard glass to around 620°C (1,148°F) and then rapidly cooling it. This process, known as quenching, creates surface compression, making the glass more resistant to impacts and thermal stress.
## Key Benefits
– Safety: Breaks into harmless granular pieces.
– Strength: Resists scratches, cracks, and thermal stress.
– Versatility: Used in car windows, shower doors, phone screens, and building facades.
## Applications
Common uses include:
– Automotive: Side and rear windows.
– Construction: Glass doors, balconies, and skylights.
– Consumer Electronics: Smartphone and tablet screens.
## Limitations
Once tempered, the glass cannot be cut or drilled, so it must be shaped before treatment. It is also more expensive than standard glass.
## Conclusion
Tempered glass is a reliable and safe choice for applications requiring durability and breakage resistance. Its strength and safety features make it a preferred material in various industries.
