Tempered glass is a high-strength "safety glass" created by heating annealed glass to over and rapidly cooling it, making it 4–5 times stronger than regular glass.
It shatters into small, blunt, cube-like pieces instead of sharp shards, making it ideal for high-traffic or safety-critical applications.

Benefits and Key Features
Safety: Breaks into small, harmless pieces, reducing injury risk.
Strength: Highly resistant to impact and thermal stress, including high-temperature differences.
Versatility: Used in vehicle windows, shower doors, tabletops, refrigerator trays, and phone screen protectors.
Heat Resistance: Ideal for fireplace doors and ovens.

Disadvantages and Limitations
No Post-Manufacture Modifications: It cannot be cut, drilled, or resized after tempering; all modifications must be done before the process.
Spontaneous Breakage: Rarely, contaminants can cause it to shatter spontaneously.
Edge Weakness: While the surface is strong, the edges are more vulnerable, and a sharp impact on the edge can cause breakage.
