I imagine after oven baking, it's unlikely that further outgassing or
sintering needs to take place, right? They sure pump "clean."

If you won't, I bet Dirk will bet the farm, maybe the whole country. ;-)
And the results do speak for themselves. In my experience, I've not seen
cleaner, brighter (for longer periods of time, too) looking tubes than some
of the Dutch neon. (Insert photo of Dirk grinning like a proud father,
here.)

So, you would do baking prior to electroding. I guess it would allow more
contaminants to escape the unit if baked before electroding. Could
"standard" electrodes hold up to this, though, if you wanted to do it after
or doesn't that make any sense? Is the only way to do bake
post-electroding to have an oven pumping system? I'm wondering this as I
saw the shop that does the oven pumping doing it, obviously w/ the 'trodes
on and I'm wondering if completed units could be baked, then electrocuted,
er, bombarded.
