...Swim has not used gvg so cannot comment on its effectiveness but based on responses here it sounds like folks like it. That said, swim looked at vaporgenie and even bought one, not the glass one, and couldnt figure out how it prevents the running away of the spice from the heat. He bought the aluminum bat model and even after attaching an eight inch tube to it, alot of spice ran into the tube and was not recoverable. With the GVG, it appears that spice will do the same thing, no? I guess you could heat the glass where the spice ran to but that would present the same pyrolyzation issue it would seem. Also, I could see a technique where heating the GVG glass below the spice chamber before torching thru the ceramic may help prevent runaway spice but havent seen that technique mentioned.

Swim would like to try the GVG but doesnt want to buy one without knowing how it deals with runaway spice.

Regarding runoff, a thin disc made from copper “scrubber” or other material, or a bed of plant material will prevent runoff. With a copper mesh disc, there is 0% runoff.

Understood if you need the scruuber/mesh disk then there is runnoff that is captured. So after accumulation of the runoff, do you wash the scrubber or mesh disk in NP or other solvent to recover the spice or do you throw it in the GVG chamber and vaporize through it?

"When DMT is gently heated in a GVG, one is not even aware that vapors are being produced and inhaled. I don’t know of any other device that shares that characteristic."

If one is aware of vapors being produced and they can be seen, does that necessarily mean the molecule is being Pyrolized / degraded?

The mesh isn’t used to collect runoff, it’s used to prevent it. The dose is placed on the mesh, the mesh disc is placed in the GVG chamber, and the DMT is vaporized. After the dose is vaporized, there is nothing remaining on the mesh and no runoff either.
