It seems to me that using an oil burner with DMT crystals has to be done the same way one would do it with meth crystals. You can burn those, too, but I know people who are very skilled. You just have to practice a bit with the distance you hold the flame from the bowl- Just close enough that you melt the crystals and heat them into a vapor and then a long, slow draw as the crystal vaporizes. I haven't done my extraction yet. I'm just going by what I've seen. If you are careful and don't hold the flame too close, you should not have a problem with wasting much, if any, of the crystals. Using a Bic is probably best for this. I've only ever seen people use butane torch lighters to clean the pipe. And I've never seen people smoke crack from an oil burner, just from a straight stem with some steel wool set in the end upon which they would melt their hit before using the lighter to heat it and the glass from the outside. Now THAT might be a method to look in to, also. Sounds very close to the methods mentioned in some of the other posts.
