Curved, laminated glasses traditionally are used in automotive applications. However, they are becoming more prominent in commercial construction as “anti-vandalism” and “shielded” glass, with the purpose of adding security to physical environments and people.^1,2

The manufacturing process for curved glass is complex. Without tight process control, significant amounts of flaws and breakage can occur, resulting in costly rework or scrap. This situation was the case in a medium-sized curved glass manufacturing plant in Curitiba, a city in southern Brazil, where 20% of pieces had to be scrapped.
