I love physics. Is was my second favorite subject after art.
Chemistry was up there.

what i kept wondering about was howcomplex does it have to be?
blowers, motors, pipes....cones shaking loose.
a chimney...what a concept.
it is just a natural draft chimney.
and, i more and more think that a piece of heavy duty
plastic sewer pipe would work just fine. a 1 inch stainless pipe
from kiln to plastic. use some sort of automotive/heat sensitive
glue.
there is more than enough cold air coming in from the bottom
to off set the warm air coming from the one inch pipe leading
to the kiln.
most of you would find it hard to find a 4-5 inch solid stainless
piece of pipe...10 or 12 feet long...one piece.
a guy gave me that one day....and bingo..there was my chimney.
(never refuse a nice piece of stainless pipe when you are a potter.)
i saw a guy once use flexible stainless pipe that is used
on semitrailer trucks. that big stuff. he vented his kiln
with a small blower in a window. sucked it out of the kiln.
(might have been in cm...years ago.)
so, i thought..solid chimney would have to work.
it does.
if one wanted to get extra fancy...use sheet kaowool between
the layers of the kiln, and around the cover...stuff the peeps
with kaowool. just have one that comes out for the
safety cone viewer.
the tighter the kiln...the better the draft up the pipe.
some have suggested a few holes in the bottom of the electric
kiln...but i have not needed it. when the kiln is firing on a cool
day...you can see the bits of smoke and steam coming from that
stack.
i just stuff that piece of foam back in when the kiln is done.
don't want ice cold air coming back down the stack in winter.'
the bottom of the pipe is about a foot off the floor.
yes marcie, cool to hot moves the air out.
my god..physics...can you beat all.
i think it was a korean physicist..held captive in japan that
invented the chimney...he was also the first one to write
a position paper on:
`you stick your eye in the peep hole at cone 11, it will burn your eye out.`
just like Ralphy andthe BB gun.

Vent experimenters:
You can get a variety of stainless pipe sizes and 500=B0 silicone =
sealant=20
at http://www.aircraftspruce.com/
They have a lot of other interesting supplies too. I used their heat=20
shrinkable Dacron on my wood frame kayaks.
