Abstract
In the thermal cycles utilized for frit sealing glass members together for forming a glass housing and for baking-out such housing, shielding means are provided to protect and shield those portions of the glass members having multiple surfaces which would otherwise be exposed to excess thermal energy, from such thermal energy so as to inhibit the formation of detrimental thermal gradients within the housing structure.
