Tempered glass is a type of safety glass processed by controlled thermal or chemical treatments to increase its strength compared to normal glass. When broken, it shatters into small, relatively harmless pieces rather than sharp shards, making it ideal for applications where human safety is a concern. This specialized glass is commonly used in car windows, shower doors, mobile phone screen protectors, and building facades. Tempered glass is approximately four times stronger than annealed glass and can withstand higher temperatures, making it exceptionally durable for everyday use in residential and commercial settings.
