Sandstone vs. Grade A Lava

Sandstone belongs to the natural stone classification, while grade A lava belongs to the oxide-based engineering ceramics. There are 11 material properties with values for both materials. Properties with values for just one material (10, in this case) are not shown.

For each property being compared, the top bar is sandstone and the bottom bar is grade A lava.
