Hi Jack,

I had an old "Party Bulb" lightbulb that would glow green on a coil.  The
filiment was broken and would whip around when powered.  The bulb would show
green swirls that would look similar to the coiled filiment, and it would
glow for a short time after powering.  All other lightbulbs would have a
purple glow to them.  I still have this bulb and some old photographic
paper, and will test it as soon as I can get one of my smaller coils back
together.
