hose) and warm the tank with that to get one more pot out. Don't do
that either. I tried not to be around when he fired raku.

well, i have done it for fifty some years.
no big deal. i fire at minus 25F sometimes.
and, anyone with modern knowledge of firing kilns
would more than likely `down fire` the kiln anyway.
so, if it is 50 below, thirty mile winds... you would re/lite
the kiln at 1800F and fire for an hour, do it again if it cooled
too fast.
but, in most cases, ambient air is meaningless.
what does the kiln know about outside temps when the kiln is at a
thousand degrees F?
now, propane tanks are another story. they will freeze up like
crazy. those need some sort of protection...blankets, tarps, whatever
you can rig up. i have even used an electric blanket. some pour warm
water over the tank. but, that is a pain in the butt. and you wind up
with a big frozen mess.

actually...not so stupid... preheating propane is very common in Northern =
climates. No real danger to heat the tank or the pot that feeds the tank..=
..but not to feed fire to the propane raw...as in a burner...before you wan=
t it to ignite.
Alaskan potter for many years...then to vermont....also a cold place.
We had an 18,000 galoon tank at Bennington Potters and HAD to use a pre hea=
t system to make the propane flow to the tunnel kilns.. in winter.....it us=
ed real flames to make the gas flow....but of course it was heating the lin=
e...and not simply exposed to the raw gas..... an evaporator.
we do what is needed in cold climates to get the gas to burn. Propane or b=
utane is a pesky creature. Natural gas is easier to use.

My standard technique is to pour cold water onto a freezing tank; cold wate=
r=3D
is a lot warmer than freezing Propane! (& safer!!)

Hello All,
Quite a few years ago, when I used to only gas fire, I would fire in
the dead of winter sometimes. Once in January or February when it was
near zero F, the propane tank started to freeze up. It was a 500
gallon tank and had about 125 gallons left in it. The firing was still
only 2/3 of the way done, so I went and got a bucket of water out of
the hot tub and poured it slowly over the tank. Lo and behold, the
pressure went up one pound for each bucket of hot water. With about
20-25 trips back and forth from the tub, I was able to make it through
to cone eleven.
Good firings,
