This sounds like a less than great idea, concentrates are meant to be smoked and the volcano is designed to be used with dry herb. That being said, since you're just vaping the oils from cannabis, then I would assume you just need to set it to the boiling point of THC
Wrong wrong wrong. The Volcano comes with a "liquid pad" that you put on the bowl and it's specifically for blowing bags with oil. Just start at a lower temp and go higher till you're satisfied, no big deal! Try 6 if you're on the Classic and turn it up a little bit after each bag.
