Cesium Bromide vs. Lead-alkali-silica Glass

Cesium bromide belongs to the non-glass optical ceramics classification, while lead-alkali-silica glass belongs to the glass and glass-ceramics. There are 5 material properties with values for both materials. Properties with values for just one material (15, in this case) are not shown.

For each property being compared, the top bar is cesium bromide and the bottom bar is lead-alkali-silica glass.
