GM-120 Glass Ceramic vs. Glass-bonded Mica
Both GM-120 glass ceramic and glass-bonded mica are glass and glass-ceramics. There are 10 material properties with values for both materials. Properties with values for just one material (11, in this case) are not shown.
For each property being compared, the top bar is GM-120 glass ceramic and the bottom bar is glass-bonded mica.
