Optical Silicon vs. Alumina-lime-silica Glass

Optical silicon belongs to the non-glass optical ceramics classification, while alumina-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 (23, in this case) are not shown.

For each property being compared, the top bar is optical silicon and the bottom bar is alumina-lime-silica glass.
