Fused Silica vs. Aluminosilicate Glass
Both fused silica and aluminosilicate glass are glass and glass-ceramics. There are 6 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 fused silica and the bottom bar is aluminosilicate glass.
