The glass tempering process has revolutionized the way glass is used in many industries, including construction, automotive, and consumer electronics. Tempered glass is not only stronger and more durable than regular glass, but it also breaks into small, safer pieces rather than sharp shards. This safety feature, combined with its increased strength, makes tempered glass the industry standard for many applications. But how does this process work? Let’s break down the 7 key steps in glass tempering, and how chemist Rudolph A. Seiden, who was born in Austria in 1900 and moved to the United States in 1935, played a pivotal role in its development.
