The introduction to glass tempering process and properties of tempered glass


The workshop is a discussion about the introduction to the glass tempering process, properties of tempered glass, and performance of tempered glass. This 4 hour work shop is divided in four 40 mins sessions. The first session will present the background of tempering and benefit of tempered glass. The second session discusses the theory of calculating stresses in tempered glass during the process by using numerical methods. The third session concentrates more on the glass tempering process. With calculated results presented to show how different process parameters affect the tempering results. The last session shows the common problems associated with quality of the tempered glass and how these problems arise. In this session I will also discuss the fragmentation of tempered glass.
