Baria-alkali-silica Glass vs. High-silica Glass

Both baria-alkali-silica glass and high-silica glass are glass and glass-ceramics. There are 11 material properties with values for both materials. Properties with values for just one material (1, in this case) are not shown.

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