Seeking My Shangri-La
You can do an internet search for any word you want but you are wrong. I have combusted in the FF before and it was true combustion.Sorry, 400 degrees is 400 degrees, which is well below the material's ignition temperature Do an internet search for "pyrolysis". ABV can be black and ashy in the Firefly, but that is the end stage of the oxidation phenomenon of pyrolysis. The oxidation rate of pyrolysis is less than that of combustion, which has a very rapid rate of oxidation, with it's attendant by-products. I am not trying to be annoying and abstruse here. I am just applying my physics background to vaporizing with the Firefly. I have had my Firefly for two weeks, and it is stellar !
Anyhow, others have given reasons why this happens. There you go...you learned something today.
