The Development History of Tempered Glass

The development of tempered glass can be traced back to the mid-17th century. A Rhine prince named Robert once conducted an interesting experiment in which he placed a drop of molten glass in cold water, resulting in an extremely hard glass. This high-strength granular glass is like a droplet of water, with a long and curved tail, known as the "Prince Robert pellets". But when the tail of Xiaoli was bent and broken, it was strange that the entire Xiaoli suddenly collapsed violently, even turning into fine powder. The above method is similar to the quenching of metal, which is the quenching of glass. This type of quenching does not cause any changes in the composition of the glass, so it is also called physical tempered, hence tempered glass is called tempered glass.
