Hey Howdy everyone-
I finally updated my webpage; frankly, my very least favorite thing to
do in the summer...
I'm at www.incandescentsculpture.com-
Under 'Vacuum Tubes I've got a little writeup, and video of what I'm
calling the Fuxie
Those offended by Anglo-Saxon swearing should
Hey John,
Thanks!
I've been pondering that nitrogen 'afterglow' for awhile now; seems like
there's some fanstastic potential there.
(Esp. in the realm of cold-cathode tubes, eh?)
Been saving up for some D2, have to put 99.99% nitrogen on the shopping
list...
Cheers-
On
Hey again John,
Just get some little 'seed' beads from the bead store for spacers.
If you've got ultrasound, I recommend it- there can be a little
refractory sludge in 'em from the production.
I made a few 'crackle' tubes using black seed beads and neon about 10
years
Jens-
Great! Keep going!
Congratulations on getting a good seal and vacuum; very few people
get that far-

Hey Dalibor and others-
I don't feel that these are the right getters for nixie tubes.
The literature lists them as thermally active- they only absorb if you
put them somewhere hot.
Many styles of getters are made this way; most tubes do run quite hot,
beacuse of the filaments..

Hi,
good work on the small glow lamps! What kind of burner do you use?

I, too have messaged the 'seller' -
Notice the blue glow in the picture that indicates the rectifier is
under load at the time of the photo, which wikipedia has as 2005.
We should report this before it ends, eh?

Hey Jens-
The 'bakeout' cycle of processing any glass vacuum device is
critical for long life-
Every surface, and every material in the bulb has a film of water
vapour on it, as well as anything else you left there with your
fingers.
The water has terrible effects on any filament, and even
Howdy Jens-
If you've got any kind of spark coil, you don't need a vacuum
gauge. The color of the discharge in the gas remaining in the tube
will tell you the vacuum.
You'll really need a 2-stage pump to attain enough vacuum (i've been
using an old Welch for 15 years)..
Once the pump has
Hey All,
I agree- a big pinch seal with 10 wires, and 2 'dead' wires for
supports would be easiest.
Pinch seals of that size are also tricky- the tube must be carefully
pre-shaped for the seal; just heating the open end of a round tube
causes it to slump down the middle as the glass thickens up
Gentlemen-
My name is Dylan Kehde Roelofs; I've been a scientific glassblower
for 20 years, and I believe I can answer a few of your questions..
First, check out my website at www.incandescentsculpture.com - I
