A glass envelope for a cathode ray tube ( ) and a method of production. The envelope comprises ( ) a panel member having a thickness (t) that is defined by an equation which involves net tensile stress; wherein the panel having a net tensile stress not exceeding 1150 psi, having a surface compression induced during panel manufacture, and having an implosion protection band ( ) shrink-fitted around a skirt ( ) on the panel that augments surface compression in the panel ( ), whereby the panel thickness is substantially less than that of a corresponding untreated tube envelope.
