SEARCH for the treasure...
When I was researching on Zirconium:
depending on how the Zirconium is made, it can be harder then glass on the MOH hardness scale, so glass joints should not scratch the extended 10mm mouthpiece.
However, I have only used PBW on my glass rigs. I remember a single post here somewhere, that claimed PBW scratched or left marks on his glass rig. I have never experienced that. I doubt it would effect something as hard as Zirconium, but I’ve never tried it.
