Part 3/6:
The discussion then shifts to different types of glass, especially tempered glass and laminated glass. A clarification is made that sapphire-coated glass primarily affects tempered glass, with the tempering process involving certain chemical modifications. Notably, the process of tempering can induce nickel sulfide inclusions, which can cause unexpected breakage later on. This detail highlights the complexities involved in glass manufacturing and the potential safety concerns associated with tempered glass.
