Need lenses for protecting your eyes during furnace observation?

Cobalt Blue Glass for Furnace Observation

Cobalt blue glass is used in special furnace 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.

If you’re interested in furnace observation cobalt blue glass, here’s what you should know:
Furnace observation cobalt blue glass is used to decrease the brightness of furnaces during metal and glass work.

Cobalt blue glass has special properties that both allow you to see better into extremely bright furnaces and allow you to see more clearly and with more contrast the objects you’re working on.
Cobalt blue glass does not protect from infrared and should not be used in lieu of green IR glass.
Furnace observation is almost always the only thing that cobalt blue is safe for, but it works better than any other lens for that function.

Cobalt blue glass is extremely hard to find. Ours is of the highest optical quality and meets rigorous standards for glass quality.

    How much for glasses or a small bulk order? Need them for furnace viewing at hot temperatures. I look at burners in furnaces to see how long they are and set them to proper lengths for the temperature needed in a forge shop. Is it possible to get just a piece of rectangle shaped glass also?

    We have tried several different blues to distinguish between slag and steel working with a AOD furnace and haven’t had much luck finding a good one since the 90s not sure if we have tried yours

    I would like to know if furnace observation cobalt blue glass is also helpful for distinguishing between molten metal and slag flowing over the metal for casting operators.

    • rxsafety says:

      Cobalt Blue Glass was developed for furnace observation. It allows the inspection of molten substances during melting procedures. It provides blocking of 99.9% of the infrared radiation in the 780n to 2000nm range that is harmful to the eye. At the same time, it filters much of the Yellow/Orange and Orange/Red wavelengths, allowing you to distinguish between slag and other differences in the molten materials. When mounted in a goggle or eyeglass frame, it can be used for torch brazing and soldering. It does not provide protection from Ultraviolet, so should not be used in welding operations.
