A genuine Propane Puzzler
In the spirit of giving something back, I offer the following story of a weird problem my wife and I experienced on our first cold weather trip. I now know the answer and I wonder if anyone here can n...

with regard to reading vapor pressures = temperatures, the amount of boil off must be taken into consideration. A pot, cylinder or tank with low amount boil off surface area will become COLDER than the liquid was when starting off. Expansion. When the expansion rate is very low the tank temp will remain near ambient temp, when the expansion rate is very high (high amount of boil off) the temperature can *easily* sag -20F.
In extreme areas, 97% propane and 3% methane is the mix to achieve proper vapor pressure. The Soviets transported LNG into the remoter regions of Siberia where -80F was not unheard of.
In the winter in the mountains I always had pots of butane to start charcoal with. Some liquid was allowed to soak into the carbon then when set alight it burned furiously for a few minutes. And not a hint of taste contamination.
