Sandstone vs. Machinable Glass-ceramic
Sandstone belongs to the natural stone classification, while machinable glass-ceramic belongs to the glass and glass-ceramics. There are 17 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 sandstone and the bottom bar is machinable glass-ceramic.
