Cobalt Blue Glass

Cobalt blue glass is used in steel work and cement plant observation scenarios where IR protection is not required, but observation of bright furnaces requires blue eyewear to be able to see into the furnace better.

Cobalt blue glass is NOT a good substitute for green IR glass. Cobalt blue lenses do not protect the eyes from IR radiation like the green IR does, but cobalt blue lenses are not designed for that. Furnace observation cobalt blue glass is designed with the furnace observer in mind, and it allows those who are observing hot furnaces without IR radiation to see into the furnace so they can reduce eye fatigue and increase their vision of the items in the furnace.

The spectrum of cobalt elements makes it incapable of absorbing blue light (i.e., reflecting or passing through blue light, while completely absorbing yellow light with different wavelengths of blue light). Blue cobalt glass filters yellow light because of the presence of cobalt ions.

In observing the flame reaction of potassium needs through cobalt blue glass, because the potassium compounds are not pure, often mixed with some impurities, such as sodium (not easy separation), in the flame reaction, due to the flame yellow sodium, interfere with the flame reaction of potassium (purple), so you have to take yellow light filter, by the light of the principle of complementary color, yellow and blue are complementary colors. Using blue cobalt glass to filter out the yellow light, the potassium’s flame-color, purple, is clearly visible.
