What is a key feature of tempered glass?

• A. It is weaker than ordinary glass
• B. It cracks without shattering
• C. It is more difficult to break than ordinary glass
• D. It is completely noncombustible

Answer: (C)

Tempered glass is designed to be stronger and more resilient compared to ordinary glass. The tempering process involves heating the glass to high temperatures and then rapidly cooling it, which creates internal stresses that enhance its strength. This process allows tempered glass to withstand greater impacts and stress, making it significantly more difficult to break than standard glass. Additionally, when tempered glass does break, it shatters into small, blunt pieces, which minimizes the risk of injury. This property is particularly beneficial in safety applications. However, tempered glass is not completely noncombustible; its behavior in extreme heat situations is more about not shattering dangerously than being entirely fireproof. Thus, the characteristic of increased strength and impact resistance makes it a key feature of tempered glass.
