- Definition:
- Toughened glass, also known as tempered glass, is a specially treated safety glass.
- Manufacturing Process:
- Step 1: The glass is cut to the desired size.
- Step 2: It is heated to around 620°C (1,148°F).
- Step 3: Rapidly cooled, putting the surfaces into compression.
- Strength:
- It is up to 5 times stronger than regular annealed glass.
- Safety Features:
- Breakage Pattern: Crumbles into small, granular pieces.
- Risk Reduction: Less likely to cause injury compared to regular glass.
- Applications:
- Automobile Windows: Used for its strength and safety.
- Shower Doors: Chosen for safety in case of breakage.
- Glass Tables: Ensures strength and reduces injury risk.
- Building Facades: Provides structural strength and safety.
- Appliances: Often used in oven doors and microwaves for heat resistance.
- Advantages:
- Durability: Resistant to breakage and thermal stress.
- Safety: Minimizes injury risk with its unique breakage pattern.
- Disadvantages:
- Cost: Slightly more expensive due to the specialized manufacturing process.
- Customization: Any alterations, like cutting or drilling, must be done before the tempering process.
