SWIM got his GVG today and is very happy with it! SWIM has just had a few mild hits 20-30mg to get a feel for it.
After a few hits SWIM has noticed white melted crystals forming in the U bend of the pipe, basically looks exactly like what SWIM loaded into the pipe.
SWIM has got a volcano liquid pad and 2 screens in place to prevent leakage, swim is only using a standard lighter tho, not a torch lighter, is this SWIMS problem?
Thanks for any tips!

The spice is going to condense on the insides of the GVG no matter what. Regularly clean it with warm IPA or acetone and then evap it to collect for future vaping. The thicker the build-up, the more will condense, so if you let it get too thick, you will be getting much amounts into your body using the same initial weights.

Crystals condensing on the glass is normal. Oil running down the neck above the U bend means you're leaking spice. Also are your two screens on top of the pad or under it? I had bad results with a screen on top of the pad but once removed, it worked perfectly.

Yeah SWIM is pretty sure he is leaking spice! He has the 2 screens under the liquid pad.
Any suggestions as to why this may be happening? Haven't heard anyone else having the same problem when using volcano liquid pads?

are the crystals sitting well on top of the volcano? Try taking a first small hit, warming up enough for the dmt to melt but not to vaporize (Too much at least). Then remove your ceramic filter and look. Where is the dmt? Did it melt through the sides? Did it melt inside the liquid pad?

The dmt should in no way pass through the liquid pad, so maybe you didnt put it too well or you had the GVG turned at an angle when vaporizing and it melted through the sides?

The last option is to add a bit of herbs on the screens so that melted dmt wont run through, or pre-infuse some herbs and then smoke. But the liquid pad should def work

SWIM wont get a chance for a few days but will try this smoke a bit then check idea when he can.
Thanks for the tips.

Someone posted a pic of their GVG with white crystal condensed on the u bend, looked so damn cool...

Im going for a whole bong

That would be me, in this thread.

Does anyone know of a photo of the bowl loaded? To give a first timer an idea of the best way to load it.

Here is a pic of Ant's loaded

The first pic with the crystal condensed on the U bend is not what swim is getting, swim definitely has a leak. swim doesn't understand why he seems to be the only one who is having this issue, strange?
Does anybody use a regular lighter with their GVG? I think this might be the issue, swim has an Arc in the post
Also someone mentioned using a bed of herb to prevent leaking, would the herb combust at all in the chamber?

No the herb should def not combust.

Adjust/stretch the pad so that the dmt only melts in the middle an doesnt run on the sides. But yeah otherwise try the herbs too..

I dont think the lighter should be the issue, its just the heat source. In any case a torch lighter will be great for other reasons

SWIM has a torch and a bic and prefers her Bic with the GVG. Maybe her $5 torch just isn't the bee's knees, but Bics work just fine.

SWIM tried taking a very small hit then checking the bowl and the spice is going down into the liquid pad not down the side. SWIM has compacted the pad a bit and this seems to have helped a lot, SWIM also tried using a torch lighter for the first time today and did not enjoy it so much . . . .

SWIM has a few questions, forgive him for being a noob please.

SWIM found the vapor a lot thicker with the torch, it tickled swims throat a lot and made SWIM feel very nauseous which made for an uncomfortable 4-5 mins! When SWIM breathed out after using the torch lighter there was a LOT of thick vapor/"smoke" yet when the bic was used there was almost no vapor breathed out. Maybe its just SWIMS technique that needs working on but controversially SWIM definitely seems to prefer the bic to the torch.

Is it normal to breathe out heavy vapor?

Does anybody else prefer to use a bic style lighter with their GVG?

And finally, endlessness recommended using a small herb bed to help prevent leakage, could somebody recommend a nice tasting, non active herb that they use for this purpose?

Thanks for all your help!

Mullein all the way

To me it sounds like you are giving the GVG to much heat. And no its not normal to breathe out heavy vapor, maybe you not holding it in long enough? I too have had that tickling sensation when too much heat is applied, thats my cue to lay off the heat a bit

I always use my torch, I find it has more direct heat than a bic. Also if a bic is used incoreclty soot begins to build up on the ceramic bit.

Thanks gammagore. You confirmed what SWIM suspected, will just have to practice more and SWIM shall go seek out some Mullein

One last question, is it dried mullein one would use??

Dried, yes. Any herb that one uses should be dry.

Amazing crystal formation there. Thankyou for posting that again otherwise i may have not found it & seen it again...
Look at the swirls on the bottom right that look like the curls of a leaf, and that central crystal!

SWIM reports back a bed of herb (mint in this case) worked a treat! No more leakage and really tasty.
Next experiment on the list, Changa, once SWIM can find some bark, getting hard to find in the UK
