Infrared Transmitting Glass vs. Granite
Infrared transmitting glass belongs to the glass and glass-ceramics classification, while granite belongs to the natural stone. There are 10 material properties with values for both materials. Properties with values for just one material (9, in this case) are not shown.
For each property being compared, the top bar is infrared transmitting glass and the bottom bar is granite.
