Abstract: A water removable material ordinarily used as a brazing stop-off - i.e. to restrict the flow of a molten metal and thereby to prevent wetting of an underlying surface in a brazing or soldering process - has been found useful presently as a means to prevent oxidation of, or other damage to, terminal metallurgy of metallized glass components during protracted periods of baking, gas-filling and glass sealing processing incidental to fabrication of gas discharge display panel assemblies. The subject baking, gas-filling and sealing processing involves hours or even days of variant temperature treatment, which should be distinguished from seconds or at most minutes of brazing treatment. The protective function required of the water removable coating during this prolonged processing period is considered unique and eliminates certain application and removal process operations associated with the use of other protective media (e.g. sintered glass frit).
