@Herr_Dampf
Thank you for offering helpful contacts. I appreciate all of help.
I live in EU, Czech Republic to be exact.
I tried to pm you, but you've some security set up on your profile that prohibits me from starting a conversation with you or visiting your profile.
Breaking any of my vapexhale glass was my nightmare.
Because I don't know any glass blowers at all, especially in EU.
I'd really appreciate any useful contacts.
It's the only option.
I can't glue it because the joint is shattered and the EVO male joint get very hot.
It couln't be used directly and I just don't trust glue.
And I can't replace it because they're not made anymore.
Nor any piece similar enough that could be
as perfect to put on top of stackable bong.
If there is any other piece with an 18mm unguarded input from a bottom, a good percolator, splash-guard and an ice-catcher, then I'd love to hear about it, but I'm pretty sure there is no piece other than this Vertigo HT matching this description. Maybe in US, but i doubt in EU where finding ANY HT is extraordinarily rare.
