Topic: vacpots and butane (11 msgs / 251 lines)
1) From: John M. Howison
I share the concern about butane vapors' effect on the sense of smell.  For
safety reasons, and despite the charm of brewing at table, I have already
shifted to using my vacpot on the kitchen stove.  Using a wire device to
minimize the surface temperature of the pot is no trouble.  Which of the vac
pots that SM offers has the sturdiest glass?

2) From: Michael I
I use a butane burner, rather than the alcohol ones.  My impression is  
that I've suffered no ill effects from it (I haven't been huffing it  
or anything, I'm just in the kitchen while the coffee is being  
brewed).  The butane burner works far more quickly than the alcohol,  
and it's pretty convenient.
I would have thought that butane burns about as clean as my gas stove,  
but perhaps this is not the case.  I'm sure someone on the list knows  
definitively and can enlighten us.
I use a 5T Hario Deco vac pot, and that's worked well on both the  
butane burner and my stove top.

I'm curious why more people don't opt for a stove top vacpot like the bodum
santos (which is what i use).
Is it the draw of the chemistry set look and feel of the yama or hario?
In any case, a stovetop unit would remove any risk of huffing butane in your
coffee.
Don't get me wrong, if i could get the hario five station unit like blue
bottle, i would totally get one for parties :)

Am I mistaken, or is everybody confusing alcohol with butane?
Alcohol will smell when burning, at least until the wick is up to heat.
Butane will burn a lot more like natural gas.
So I would think that the whole discussion of the "smell" of the burner
would apply much more to the alcohol than the butane.
I haven't used either, so I'm speculating, and should be ignored entirely if
I've missed something obvious!

5) From: Angelo
I've used both, but only use butane, now. Not only did the denatured 
alcohol smell but it left soot on the bottom of the globe. I also 
think that the heat from the butane lamp is hotter, although I heat 
my water in a kettle first.

Hi Doug,
Thanks for clarifying my question. I guess I was too cryptic. ;-)
I was thinking of a vac pot for my small office but wondered if the alcohol
smell would be too intrusive. I think the butane would be the best
alternative if others who have vac pots are bothered by the alcohol smell.

There's always the electric stoves that were standard at one time...I have bought a few on e-bay myself.

8) From: Rich Adams
100% pure denatured alcohol should not leave soot.
Standard version found in a paint store has an additive, that leaves the 
soot.  The kind sold for "fuel" is pure.

10) From: raymanowen
I don't know enough about chemistry to even be dangerous, but butane
couldn't be used in the northern US climes for the outdoor barbecue, only
propane because of the high boiling point of butane itself. Below 32 F at
29.92"Hg, it won't vaporize.
Just like natural gas, gotta add el-stinko to it.
In Siberia, women that keep butane lighters in their purses are known as
ex-smokers. Maybe Eddie can use it OK most of the time in Biloxi.
Butane can burn hotter and has a little higher energy content than propane.
I neither sniff butane nor smoke. Don't know what it would do to my
proboscis.
If I had a windbreak, I, too, could brew outside. Maybe not after today. The
freeze is about to win out over boil- coffee cubes.
For safety reasons, one might not conduct >any< combustion tests away from
the brewing device. eg: Rejoin party for polite conversation- - -
When the pot explodes, the conversation changes: "We'd stay and help you
clean up, but we have to hurry home and check the door bell- See ya."
Uh, oh- I just remembered- some poor slob inherited my door bell from Hell.
Couldn't bring it with us, so I left it. it runs, but the contactor latches
on the first button push.
I forgot. You have to shut off the dryer circuit breaker to stop the 7.5 hp
blower motor. I switched to gas when we moved in, so 2 spare breakers.
I used the spare electric dryer circuit. The clown insulation people ruined
my wind chest, so I just bypassed it. The closed mitered flue pipes just
speak directly when the motor runs.
The big one speaks at CCC and the short one is a fifth higher. There was a
prankster that ran down the block pushing the doorbells on a summer night. I
got up - figured it was the cops or something when we had the wimpy chimes.
I'd almost pay to see that happen now. It was a little startling before-
1,000 watts or so, converted to sound pressure waves at nearly 100%
efficiency. I never scaled the pipes to use all the wind. It timed out in 5
seconds after playing three notes- CCC, AA and maybe CCCC combination..
The high one was tunable- to about AA (like coffee- see, there's the
connection) But the guy exiting wouldn't stop to grab a cup of coffee or
flip the switch on the espresso maker.
Now it's not tuned at all, so I have no idea. What's more, I know nothing.
Cheers, Mabuhay -RayO, aka Opa!

"100% pure denatured alcohol" is an oxymoron.
