Potassium Bromide vs. Alkali-lime-silica Glass

Potassium bromide belongs to the non-glass optical ceramics classification, while alkali-lime-silica glass belongs to the glass and glass-ceramics. There are 6 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 potassium bromide and the bottom bar is alkali-lime-silica glass.
