Part 4/10:
Tempered glass is processed to break into small, rounded fragments rather than sharp shards, making it safer in case of failure. However, it is not entirely foolproof and can still shatter unexpectedly.
The Complexity of Glass Breakage: Impurities and Manufacturing Flaws
Nickel Sulfide Inclusions
In the 2010s, regulations restricted the use of tempered glass in certain safety applications. The issue originates in an impurity known as nickel sulfide inclusions, which are tiny particles invisible to the naked eye. During manufacturing, the heating and rapid cooling process can trap these impurities inside the glass.
