C-820 Magnesia Ceramic vs. Alkali-lime-silica Glass

C-820 magnesia ceramic belongs to the oxide-based engineering ceramics classification, while alkali-lime-silica glass belongs to the glass and glass-ceramics. There are 8 material properties with values for both materials. Properties with values for just one material (8, in this case) are not shown.

For each property being compared, the top bar is C-820 magnesia ceramic and the bottom bar is alkali-lime-silica glass.
