To increase the strength of the glass panel of a CRT, the temperature of the glass panel is reduced during reforming from a temperature above, preferably at least 30° C. above the annealing point, to a temperature well below, preferably at least 80° C. below the strain point. This induces high surface compression in the glass panel, paired with a low rate of compaction. The glass panel is subsequently not subjected to the usual annealing step.
