I have mentioned a few times that Vaponic works best for me with an Alcohol lamp. Maybe a few pages back i have posted a graphic about distance from flame and temp relation. Alcohol lamps are great ,check out the Biovapo. http://fuckcombustion.com/threads/vaponic-herbal-vaporizer.6052/page-26#post-1258521 The flame temperature distribution at different heights of the alcohol burner. The abscissa denotes the vertical height relative to the flame nozzle and the ordinate denotes the corresponding temperature of the symmetrical core of the flame. I like to hold the vaponic/cheaponic deep into the flame, around the 400-500 mark." Forgot to add that your should best avoid to use alcohol lamp with vapcaps.. There is too much heat transfer to the area with the rings. Those work better with torches.
