Barium zinc phosphate glasses formulated in the x BaO–(60 − x )ZnO–40P 2 O 5 composition line are investigated for their optical, thermal, and chemical characteristics. These as well as small stress‐induced birefringence were found to be governed by the BaO/ZnO substitution. In addition to the characterization of the properties, the phosphate network was qualitatively and quantitatively described in terms of Q 2 and Q 1 ratios by 1D 31 P magic angle spinning nuclear magnetic resonance spectroscopy experiments that also showed the presence of Q 0 sites. It turns out that the small perturbations of their photoelastic, magnetic, and chemical characteristics made these glasses very good candidates for use in polarization‐controlling optical devices.
