I have the Arizer Exreme similar to the volcano but smaller in size,,what I do is I preheat the burner to 260, pack the bowl and let it sit for about 2 minutes,,produces a little smoke but you get the full hit of THC, take the bud out of the bowl, if it's turned brown or dark color then it stayed on the burner too long,,it should still be a green color,,,good luck
