Soda-lime Glass vs. High-alumina Refractory

Soda-lime glass belongs to the glass and glass-ceramics classification, while high-alumina refractory belongs to the oxide-based engineering ceramics. There are 6 material properties with values for both materials. Properties with values for just one material (16, in this case) are not shown.

For each property being compared, the top bar is soda-lime glass and the bottom bar is high-alumina refractory.
