Well the correct vaporization Temperature of Spice is indeed 150-165 °C - but that is when dropped on a straight plate which is heated to that temp.
I use a Crafty Vaporizer and 170 °C seems fine. The problem is that you disperse / melt it in a liquid pad and the pad is not at 170 °C when the air will be.
Therefore some people make the mistake to directly draw when the light is green (= 170 °C is reached) and then the hot air first has to heat up the liquid pad, while the DMT does not get as hot as 170 °C of course.
By simply waiting a little bit when the temperature is already at 170 °C you can GREATLY increase the efficiency and making 170 °C already good.
So this would of course also be called *Pre-Heating* but it is a different pre-heating than raising Temp to 200+ and then back to 180 or 160 or whatever. I am veeerry sure that you won't need such a big temp at the start, more likely to just wait a little longer on your desired vaping temp. But I guess this is just preverence then.
Ok, this only applies to that system with vaporizers that use those liquid pads. But this also means that for any similar reason it would be wrong to just think *Oh nothing came, so better increase the Temperature*.
Of course you could increase it, but then you go higher than you may need, just to reduce the waiting time until the vaporization starts. And for me at 200°C it gets super harsh.
Really dont know why the correct temp is stated to be 220 °C at the volcano ; D
And also this does not unravel why you need 260 °C for your E-Zig ;D
But I can just tell it really is 150-165 °C physically and then in a liquid-pad-vaporizer it only needs to be slightly higher.
ALSO:
Could you tell a bit more about that E-Zig method? Technically I think it is not such an overkill like the crafty, but I may consider buying one as it is even more stylish and little.
You create your mixture with those 2 solvents that are always used and dissolve your spice in it, then you fill it directly in the E-Zig. So how much ml is 1 tank and how much Spice do you dissolve in it? Also how long does it regularly last, meaning how many tokes? And how much Spice do you get per hit roughyl?
THXXX ;D
