Abstract: Disclosed is a zinc phosphate glass consisting essentially, expressed in terms of mole percent on the oxide basis, of 31-34% P2O5, 0-2% Al2O3, 5-11% Li2O, 5-13% Na2O, 3-7% K2O, with Li2O+Na2O+K2O being 10-28%, 20-45% ZnO, 0-10% CaO, 0-10% BaO, 0-10% SrO, with CaO+BaO+SrO being 3-12%, and 0-2% SiO2, said glass exhibiting a stable glass transition temperature below 450° C., a working temperature below 500° C., and a water durability of no more than 5×10−7 g/cm2/min after immersion in water at 95° C. for 24 hours. The low-temperature glass of the present invention is particularly useful for producing glass/polymer blends. Glass/polymer blends containing the glass of the present invention are also disclosed.
