Alpha Quartz vs. Cordierite

Alpha quartz belongs to the non-glass optical ceramics classification, while cordierite belongs to the oxide-based engineering ceramics. There are 8 material properties with values for both materials. Properties with values for just one material (18, in this case) are not shown.

For each property being compared, the top bar is alpha quartz and the bottom bar is cordierite.
