Hey @invertedisdead is there any chance you could link to the specific quartz joint tubes you're using for your devices? I'm struggling to find something similar in the EU, maybe someone can help here.
You might try looking for a 14/23 quartz joint as I believe that size is more popular on your side of the pond. You’ll likely want the matching 14/23 adapter for a bowl, though a sufficiently deep 14/20 adapter would probably be alright.
I’m using these ones here

@invertedisdead found this, would it be viable to use in the same way as your designs?
That would work, just be advised that it’s boro glass and not quartz. Some people have better luck than others with torching boro, technically if annealed properly it should be able to handle it, but it’s much more important that boro is heated evenly to avoid any pinpoint cracks. quartz on the other hand can handle much more torch inconsistencies and variations. For filling with beads and directly torching I still recommend using quartz if possible to find.
