Alkali-lime-silica Glass vs. Fused Silica

Both alkali-lime-silica glass and fused silica are glass and glass-ceramics. There are 9 material properties with values for both materials. Properties with values for just one material (20, in this case) are not shown.

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