Tempered glass is used in applications where standard glass could pose a potential danger, because it is four to five times stronger than standard glass and does not shatter into large shards when broken. Manufactured through a process of extreme heating and rapid cooling, tempered glass is significantly harder than normal glass.
The brittle nature of tempered glass causes it to shatter into small oval-shaped pebbles when broken. This eliminates the danger of sharp edges. Due to this property — along with its strength — tempered glass is often referred to as ‘safety glass.’
The thermal process that cures tempered glass also makes it heat-resistant. Tempered glass can be used in any situation where there is a danger of the glass breaking due to impact or extreme heat.
