Safety Glass Breaks If Hit By Ceramic

Safety glass is designed to shatter differently from other types of glass to help prevent injuries from flying shards.

Safety glass breaks if hit by ceramic. Breaking your car s windows in an emergency might be tougher than you think study says. This concentrates the force of the hit to a small enough area on the glass that it can scratch and fracture it. When safety glass is damaged in this way the damage propagates throughout the glass rapidly and the tension within the glass. Safety glass is the generic name for glass which has been treated to make it safer than normal glass.

When regular glass shatters it breaks into several sharp pieces and spreads everywhere. The impact of the shard against the glass creates a tiny structural failing which rapidly spreads the tension through the rest of the screen causing it to break. Why will a piece of ceramic break safety glass but a similar sized rock just bounces off. When broken the pieces form razor sharp edges that can cause serious injury.

Normal float glass can be dangerous. Spark plugs are made of aluminum oxide ceramic which is exceptionally hard. I can break a big piece of tempered glass with a little ceramic chip. When safety glass shatters it is designed to stay in one place keeping all shards together and preventing sharp edges from harming people.

It is brittle so it breaks easily. Although effective spark plug fragments will not work all the time. Second the rock may have a hardness similar to the glass.
