High-silica Glass vs. Glass-bonded Mica

Both high-silica glass and glass-bonded mica are glass and glass-ceramics. There are 9 material properties with values for both materials. Properties with values for just one material (15, in this case) are not shown.

For each property being compared, the top bar is high-silica glass and the bottom bar is glass-bonded mica.
