Specialty glass is used in many different applications because of its brilliance and durability—for example, in building windows or as screen protectors for smartphones. However, if the stress is too high, it breaks. 100 percent shatterproof glass does not yet exist, but here at SCHOTT, we are getting closer and closer to making that dream a reality. Through tempering, the breakage of the glass can be delayed under extreme stress. If it does eventually break, this process helps either maintain dimensional stability or keep the shards small and less sharp. In this presentation, we will discuss the various methods for toughening both thick and thin glass. Using examples from real-world tests that we conduct as part of our glass development process, we will examine different stress scenarios. Examples from the fields of fire-resistant glass, safety glass, and smartphone display glass will round out the overview.
