Glass is hard to machine without it breaking unless you just dissolve
away the unwanted parts with HF acid (nasty stuff). I'd go with the
acrylic tube. It won't melt as long as you use a large diameter for a
large spark (need a 18"+ diameter for a 5 kVA pig, not cheap). Just
make sure the arc doesn't touch the tube. After a run of it's just
warm or less you're ok. 4" will work for a 15/60 nst.

Hello, Group,
While working on my Coil I am building a Jacobs ladder ( need a HV fix :)
My question is ... I have located some large O.D. Glass Vases to use
for a tube for the electrodes. But I want to cut the bottom off of
the vase, can anyone give advice on doing this to a round object. As
last resort I could drill holes for the electrodes. Or use an
acrylic tube but how likely would this material be to melt?
