Which of these is NOT considered a common feature of tempered glass?

Tempered glass is well-known for several key features that contribute to its widespread use in various applications. Among these features, increased strength, thermal resistance, and safety upon breakage are primary characteristics.

Increased strength comes from the tempering process, which involves heating the glass to a high temperature and then cooling it rapidly, creating internal stresses that enhance its ability to withstand impacts. Thermal resistance is another significant benefit, as tempered glass can endure high temperatures and sudden temperature changes without cracking. In terms of safety, when tempered glass breaks, it shatters into small, blunt pieces rather than sharp shards, reducing the risk of injury.

However, the ability to easily cut tempered glass is not a feature associated with it. Once tempered, the structural integrity of the glass is maximized, making it challenging to cut or modify. This requires that any necessary cuts or alterations be made before the glass is tempered, which is why it is not considered a common feature of tempered glass.
