Glass-bonded Mica vs. Machinable Glass-ceramic

Both glass-bonded mica and machinable glass-ceramic are glass and glass-ceramics. There are 19 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 glass-bonded mica and the bottom bar is machinable glass-ceramic.
