While on the topic of filters in front of dial lamps, I saw something
interesting on a Heathkit dial lamp once. It was covered in some kind
of
green thin plastic stuff, not paint, but something like a layer of
continuous shrink-wrappy stuff. It din’t react to the heat, stayed
its
color, and gave off the nicest green light, perfect for Heathkits.
Unfortunately the filament eventually went south.
