Very cool, i have the exact same scale and it works beautifully.
I am however having a bit of trouble nailing down proper vaping with my GVG. I don't have anyone to show me how, nor do i have anything but the GVG instructions and the (seemingly opposing) advice i've read on here. I'll try to illustrate what i do and maybe a seasoned spicer (haha, seasoned spice) can tell me what i maybe should change or what i am doing terribly wrong.
Initially i went solely by the GVG instructions, which say not to use a jet lighter and to not go directly at the ceramic disk. This much i have pretty much gathered based on what everyone else says to be false. However it seems pretty adamant about not letting the flame touch the ceramic and that even seems to be against the advice on here. What i've been doing is holding the torch directly downward into the bowl, but so i can still see all but the tip of the flame so i know it's not touching the ceramic disk. I also start inhaling very gently and slowly as soon as the flame is applied, which i also believe may be wrong. It may also be the reason i end up with a headache afterward based on another topic. Once it starts getting a bit white with smoke (not much mind you) i give it a good ~5 seconds then stop, hold, and exhale. A decent amount of smoke does come out on the exhale which makes me wonder just how much got absorbed.
On the note of hit size, i have read people talk about proper technique being able to take out a 30mg hit in one go. If i were to do this, wouldn't most of that be wasted on the exhale? Forgive me for being confused on some of this, but i've had a hard time finding decent instructions on how to use this wonderful tool and i'm starting to fear it's me just not getting it.
