You got it Chris. I have a feeling that if I want to entertain making a few
of these things then I will have to get myself a kiln and prop it up right
next to the manifold. I suppose I need to get it to 300C and let it sit and
pump for a few days. One day to heat it up and another to cool it down. I
wonder if I am on the right track? Also did you happen to notice if the
glass pellets were 5mm tubing and how close to the electrodes was it filled?
I tried it several months ago and found myself melting some of the tubulation
too.
