Since you seem to be looking at making something, would it be possible (or even worth it) to design something that could accept a meerschaum pipe insert?I think clear would be too ugly too soon. simplest coloration would be a semi translucent silver and gold fume. but the options would be limitless for possible colorations.
Doubt there's enough surface area to help too much with that, It would need a fairly regular run through with a pipe cleaner I'd guess.
If it's down to the flavors being bad, I'm tossing it anyway. I'm not smoking reburnt tar for frugality, only if the nub is so good I'm not ready to be done with it.
Something like this:
It might help with flavor, heat, condensation, etc.
I no nothing about what's practical to hand-make out of glass, so just tossing out ideas.
