Borosilicate Glass vs. Baria-alkali-silica Glass
Both borosilicate glass and baria-alkali-silica glass are glass and glass-ceramics. There are 10 material properties with values for both materials. Properties with values for just one material (19, in this case) are not shown.
For each property being compared, the top bar is borosilicate glass and the bottom bar is baria-alkali-silica glass.
