Hi Folks!
Summer is almost here, the nights are warmer and the urge to raku till
midnight has come upon me. Trouble is, I'm a rookie who has helped a lot of
others but never was involved in the actual preparations, like filling the
propane tanks. I'm on my own now, so I have a few questions.
1) I have a partially filled tank of propane as well as one empty. Can I
"top off" the used tank or does it have to be all the way empty first?
2) If I need to switch tanks in the middle of a firing, are there any
tricks or safety tips I need to know? Any chance of escaping gas igniting
outside the kiln? Or am I being unduly paranoid?
3) How come the outside of the tank frosts up as it's being used?
Sorry if these are dumb questions, but I'm starting from total ignorance
here.
T'anks in advance!

My tanks are never completly empty when I take them for a refill and the
propane guy just fills 'em up without draining them. This question may just
depend on where you go.

I have never had any problem changing tanks in the middle of a fire. Any
gas left in the hose will burn off as it is pulled into the kiln. I usually
work fast to loose as little heat as possible and if the kiln is hot enough
it will just reignite when I turn the new tank on. You could have a second
burner hooked up to a fresh tank ready to switch.

Usually this happens only when the tank is low. You can pour hot water on
it to thaw it out or turn the tank over and roll it on it's side.
Technically the liquid compressed gas expands too fast when the tank is low
causing it to freeze.

Of course "dumb question" is an oxymoron.....
