Abstract
In an integrated thermal processing method the bulb is completely processed in a dedicated oven. The inside and outside of the bulb are simultaneously heated. The inside and outside are also simultaneously cooled. During the evacuation a temperature gradient is maintained across the face of the panel to reduce tensile stresses which develop in the bulb skirt area during evacuation.
