     An oxy-sulfide bismuth borate glass system has been investigated for its glass formation possibility through normal melt-quench method. Some physical properties like mass density, molar volume, refractive index and molar refractivity are reported. X-ray diffraction pattern confirmed the glassy state. To understand the behavior of PbS in the system, analysis of variation in the percentage changes in density and molar volume of the compositions relative to their theoretical counterparts for six glasses in the system of generalized formula concentrations x PbS-(73-x) Bi2O3-27 B2O3 for 6.06=x=36.35 in mol% of components with rising mol% of PbS, is reported. Changes in physical parameters identify some structural rearrangement with the induction of PbS in the system.
