Today, we’re covering the following question received from Argentina: I wanted to know if there is any relation between the maximum length and width of the glasses to be tempered? I know the characteristics of the maximum and minimum glass size, but I don’t know if it is possible to temper glasses where the length is 15 times the width. Example: 190 mm x 2850 mm. As I know, such a long sheet of glass tends to bend the tips and break in the furnace.
Typically, narrow glasses need higher top convection during the heating process than wider glasses to keep them flat. Although there are no certain limits for the length/width ratio, narrow glasses tend to bend more easily during the heating.
From our experience, long and narrow glasses are also easier to temper when they are turned 10–15 degrees from the furnace moving direction.
