Machinable Glass-ceramic vs. Infrared Transmitting Glass
Both machinable glass-ceramic and infrared transmitting glass are glass and glass-ceramics. There are 10 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 machinable glass-ceramic and the bottom bar is infrared transmitting glass.
