ABSTRACT:
A photoflash lamp includes a glass envelope having a pair of electrical conductors forming a recessed seal with a primer material bridging the electrical conductors and extending into the recessed seal to contact the electrical conductors. Also, a process for fabricating a photoflash lamp is provided wherein the electrical conductors and glass envelope are moved with respect to one another to provide a recess in the envelope adjacent the electrical conductors. A primer material in liquid form is bridged across the electrical conductors and subjected to a vacuum to insure removal of any gap between the electrical conductors and the primer material.
