Perhaps glass seed beads would work (I've used these to make crackle neon tubing, and they worked fine). > You'd have to make your support rods thin enough to fit through the beads, naturally. One thing you usually can't see without disassembling a nixie, is that most of them have a section of tiny glass tubing that's fit over each metal support post, before the cathodes and ceramic spacers are threaded on.
