Zircon vs. Soda-lime Glass

Zircon belongs to the oxide-based engineering ceramics classification, while soda-lime glass belongs to the glass and glass-ceramics. There are 9 material properties with values for both materials. Properties with values for just one material (12, in this case) are not shown.

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