Has anybody experimented with these? They are a little ceramic disc with a hole in the middle and two wires that can reach the temps we need. The one at this link even lists aroma therapy ovens as an application. I figure dropping a shouldered tube with a screen of some sort into one might work for a DIY vaporizer beginning.
