Re: bombarding darkening

>Maybe also look at the way you're heating the glass in the torches, some
phosphors react easily to overheating. I have a local competitor who loves to
really get the glass soupy-hot, and his stuff ALL has "prestained" bends on
his blue and white tubes.<
Could you tell me more about how to avoid overheating. I seem to heat the
glass the least amount I can to make a good bend... I wouldn't say I get the
glass soupy-hot. My bends also don't appear "pre" stained. It doesn't show
until during the bombing...? It seems to start showing up when glass temp
hits 100C.

the bend to maintain the sort of plasticity I needed without overheating the
powder. <
Could you also say more about this technique...?
>it's my opinion that gauges vary and can be misleading<
Yes, I almost always use paper and a temp gauge. I, too, find inconsistency
between the gauge and the paper. Even after testing my gauge against other
gauges. Using both seems to be the best way to get a "feel" for the glass
temp. I do, though, have some confusion as to how "charred" the paper is
supposed to get to be up to proper temp.
>Give EGL double shell electrodes a try also<
I'm not familiar w/ these. I've seen many of the Voltarc double-shell
(mostly when the shells have fallen apart and the unit comes in for repair -
I tend to not use them), but not EGL.
Thanks much - all info is helpful!
