While ceramic roller properties and dimensional specifications are critical to the glass tempering process, many product and process variables influence roller performance and glass quality. The manufactured quality of the roller is essential, but the environment in which the rollers operate and the processes and procedures practiced before and during tempering directly influence the life and performance of the rollers. The combined influences of the roller quality, the environmental effects on the rollers and the roller-to- glass interface, and the methods and frequency of cleaning the rollers directly relate to the life and cost effectiveness of the rollers. These influences ultimately effect the productivity and profitability of the glass tempering operation. Additionally, scientific identification of microscopic defects in tempered glass is essential to isolating the cause and resolution of such defects.
