Alpha Quartz vs. Granite
Alpha quartz belongs to the non-glass optical ceramics classification, while granite belongs to the natural stone. There are 10 material properties with values for both materials. Properties with values for just one material (12, in this case) are not shown.
For each property being compared, the top bar is alpha quartz and the bottom bar is granite.
