Which type of glass is typically known for its strength and ability to shatter into small, blunt pieces?

Tempered glass is recognized for its durability and safety features. The manufacturing process involves heating the glass and then rapidly cooling it, which increases its strength compared to regular glass. One of the significant characteristics of tempered glass is how it breaks; upon shattering, it fractures into small, blunt pieces rather than sharp shards. This property greatly reduces the risk of injury during accidents, making it a preferred material for various applications where safety is a concern, such as in car windows, shower doors, and glass doors and tables.

The other types of glass mentioned have different properties and uses. Float glass, for instance, is the most common type of flat glass, primarily used in windows, but it does not share the same safety attributes as tempered glass. Laminated glass consists of two or more layers joined by a plastic interlayer, which helps keep the glass intact upon breakage. Lexan, a type of polycarbonate, is known for its high impact resistance but is not classified as glass. Each of these materials serves distinct purposes where their unique characteristics are advantageous, but none provide the same combination of strength and safety as tempered glass does when it comes to shattering.
