High-silica Glass vs. Low Expansion Glass-ceramic
Both high-silica glass and low expansion glass-ceramic are glass and glass-ceramics. There are 7 material properties with values for both materials. Properties with values for just one material (18, in this case) are not shown.
For each property being compared, the top bar is high-silica glass and the bottom bar is low expansion glass-ceramic.
