Marble vs. Calcium Fluoride
Marble belongs to the natural stone classification, while calcium fluoride belongs to the non-glass optical ceramics. There are 10 material properties with values for both materials. Properties with values for just one material (11, in this case) are not shown.
For each property being compared, the top bar is marble and the bottom bar is calcium fluoride.
