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.

HF is overkill (see other posts on cutting glass.)
On the acrylic tube, if the rods or your JL touch the tube, they can
melt through after less than a minute's operation.
