High-silica Glass vs. Infrared Transmitting Glass
Both high-silica glass and infrared transmitting 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 high-silica glass and the bottom bar is infrared transmitting glass.
