Marv,
On a glass tube, there would be one way of calculating the anode temp by the color it glows at. Knowing the temp characteristics of the anode material, the color is dependent upon temperature.

--- Anode temp does not give one any clue as what the seal temp is, and seal temp is The limiting factor.



So, by going to the material specs, generally know it's melting point, a temperature can be determined this way. Like you said, the anode couldn't be measured through the glass. I think Rich is speaking about the temp of the anode connector coming out of the glass on the top of the tube. This is where the leak would be if any or around the base pins caused by the heat. One thing about this mailer, good discussions can be brought up with a wealth of information available to the readers.

IR doesn't radiate "through" standard glass.

IR from sunlight undoubtedly gets through double-pane metal-film coated thermal windows. Through standard glass, even more IR gets through.
