    • The subject invention is directed at wherein either a portion of the ZnO or alkali metals, or both, found in prior art glasses, is replaced by Cu.sub.2 O, i.e., cuprous or monovalent copper. In addition to the Cu.sub.2 O substitution, the inventive glass contains a required metal oxide constituent which is necessary to enhance durability. More specifically, the present invention discloses a glass consisting essentially of, expressed in terms of mole percent on the oxide basis, of about 42-54% P.sub.2 O.sub.5, 10-30% Cu.sub.2 O, 10-30% R.sub. O and 3-12% of a component selected from the group consisting of 0-7% MoO.sub.3, 0-10 Fe.sub.2 O.sub.3, 0-10% Al.sub.2 O.sub.3 and 0-7%WO.sub.3. In addition, the composition includes up to a total of 45% of optional ingredients in the indicated proportions selected from the group consisting of 0-15% MgO, 0-20% CaO, 0-20% SrO, 0-20% BaO, 0-25% MgO+CaO+SrO+BaO, 0-35% ZnO, 0-10% MnO, 0-2% CeO.sub.2, 0-10% B.sub.2 O.sub.3, 0-2% Ln.sub.2 O.sub.3 , 0-8% F, the latter as analyzed in weight percent. The R.sub.2 O constituent is selected from the group consisting of 0-15% Li.sub.2 O, 0-20% Na.sub.2 O, and 0-10% K.sub.2 O. Furthermore, the Al.sub.2 O.sub.3 +Fe.sub.2 O.sub.3 does not exceed 10% and the MoO.sub.3 +WO.sub.3 does not exceed 7%. One final requirement of the glass is that the predominate proportion of the copper is present in the Cu.sup.+ or monovalent oxidation state.
