Alright so looking it up and doing the conversions I found that glycerin is flammable and upon further research (and idk if this has a lot to do with it) but someone was boiling a glycerin and methanol solution. The mixture and caught fire and after they had put it out they had used a thermometer and found that it was about 185 degrees farenheit. Although the extinguisher they used without a doubt cooled it somewhat foes anyone know that when making home made fluid using glycerin. In a higher wattage mod if the temperature could get high enough that the fluid can combust while in the atomizer.
