Borosilicate Glass vs. Aluminosilicate Glass
Both borosilicate glass and aluminosilicate glass are glass and glass-ceramics. There are 7 material properties with values for both materials. Properties with values for just one material (21, in this case) are not shown.
For each property being compared, the top bar is borosilicate glass and the bottom bar is aluminosilicate glass.
