Low Expansion Glass-ceramic vs. Glass-bonded Mica

Both low expansion glass-ceramic and glass-bonded mica are glass and glass-ceramics. There are 16 material properties with values for both materials. Properties with values for just one material (9, in this case) are not shown.

For each property being compared, the top bar is low expansion glass-ceramic and the bottom bar is glass-bonded mica.
