Infrared Transmitting Glass vs. High-silica Glass
Both infrared transmitting glass and high-silica glass are glass and glass-ceramics. There are 6 material properties with values for both materials. Properties with values for just one material (11, in this case) are not shown.
For each property being compared, the top bar is infrared transmitting glass and the bottom bar is high-silica glass.
