    Abstract: The lifetime of multiple capillary nozzle assemblies embedded in a glass mass, of a multiple nozzle ink-jet printer, can be increased and the thermal and mechanical compatibility of the resulting package enhanced by fabrication of the nozzles from glass compositions comprised of SiO2, ZrO2, Na2O, K2O and MgO. Inclusion of ZrO2 as well as minor amounts of BaO, MgO, CaO, and Al2O3 enhances the alkali resistance of the glass nozzles. Also, the high SiO2 content of the glasses combined with the presence of ZrO2, MgO, CaO, and Al2O3 imparts an acid resistance to the nozzles.
