Hi Guys, just an observation, but it really dosen't matter what type of device is used to 'Vapourise' DMT, but in my mind there are certain caveats. Copper or high grade stainless steel scrubber/ribbon, to spread the DMT thin and far, to be able to inhale an instant dosage, large enough to obtain a desired effect. Glass, not plastic like the large lemonade bottles with foil base, is a good idea but it can smash or break quite easily. I have seen aluminium ones but I'm distrustfull of any 'safety assurance' the makers offer. The GVG is made from 3mm (3/32" inches)thick glass and is robust as can be made from glass commercio/economically.
Technique however is of vital import. A perfect vap tastes of nothing at all, offering 20mg or so in one hit with no urge to cough. Burning it, even slightly, brings a taste all too familiar to those who have done so before. 'Chasing the Dragon' on tin foil would probably work if you want to inhale Alunimium powder.
Changa on the other hand offerers an alternative technique and process that is apparently very successful. Dissolving DMT into a solvent like Naphtha (Shellite) and infusing some Damainia herb or even low grade Cannabis is a common practice. Unfortunately many people just load up a bong without covering/protecting the DMT with a layer of uninfused herb, or even ash, and then 'burn' the DMT. DMT vapourises at a lower temperature and gently lighting a covered DMT herb infused bong will vapourise the DMT before or as the bong cherries.
Directly touching flame to DMT will burn it. No matter how elaborate or thought-a DMT machine is made the ceramic flame filter with the GVG hasn't been replicated IMHO, and is a helpful device helping to prevent burning.
Re-crystalising will help to reduce the risk of contaminants being inhaled too. Lots of yellow may contain unwanted tannins and plant oils that were not removed in the extraction process. This will also effect, considerably, the blast-off dosage. Personally I prefer one or two gentle lung-fulls and lay back and savour for 8 or 10 seconds and gently exhale. No taste, no cough no stress. I did go to the trouble of ordering one on-line and getting it shipped halfway around the world. I have had it 4 years and when I clean it, it looks brand new. I only use this device because I have tried all the rest.
Hope this helps
Kind Regards G
