kurt, nils and i are busy writing a review of the wood conference for a
magazine,
and with `one eyed jack`, being crabby about his eye...well, we are behind.
a general description of what we heard...not big science please.
so, nils and i attended a session on water injection into wood fired kilns..
(not gas, they are wet already.)
one swede, (great guy) is building an aquagama kiln...going to inject
about 20 gallons of water through pipes as he fires.
he is a ceramic engineer, so knows his stuff. (scary shit, boy.)
the Australians are just wetting their kilns before they fire...hose them
out with water...(owen rye) and with building their kilns on streams and
leaking water springs...the water just seeps in while firing.
one fellow diverts water from a creek around his anagama, and keeps the
ground saturated...(at first for safety, now to get the water into the kiln.
breshnahan from minnesota (huge wood fired kiln) just pores about
4 liters of water in his kiln each day of the 6 day firing.
there were many formulas on the board, and fast talk of 02, hydrogen
moving fast through the kiln....and when oxygen leaves water,what you
have left is hydrogen, and that burns. so, in essence the water burns.
but, man, when engineers talk of this stuff, it goes past my ears real fast.
i understand, get the idea, but, i don't want to report it as fact..that is
for
others.
the chinese are believed to have done this many years ago, and it seemed
to double the strength of tiles.
so, the bottom line:
water takes away the black smoke and carbon.
water increases reduction.
water will make the kiln fire faster.
water will make the kiln fire better pots.
just don't use so much you put out the fire.
happy balance.
we are thinking that we may mist some water from a
pump sprayer during the firing of the train this week.
of course many of you have already sprayed water mixed
with either salt or soda into kilns with a positive result.
BUT....BE CAREFUL...STEAM IS A KILLER.
TEST, TEST, TEST....SLOW.
remember, i am just reporting things i heard...i have never done it.
kurt and i are going to really be careful.
the conference was just wonderful, well organized, easy, and had a great
spirit of good folks, sharing. not many `pumping egos` about...just enough
to make one smile. the shows were just great....and the gang seemed to move
from one venue to the other en-mass.
433 folks that like fire and fuel. (but, if is often forgotten that the
mexicans
fire at low temp....WITH WOOD. ) not a word was mentioned by anyone about
pit, sawdust, low temp wood fires. etc.) it was anagama city all the way.
one of our fondest memories was the number of `kick ass` women that are
building their own kilns, anagamas, trains, bourries....and making them work.
we got a ton of information from judy duff (see her in cm this month in
the brent
wheel add.) and her friend from canada....train kiln women, and man they make
those things sing.she convinced kurt and i to `not` rebuild...just stack it
right, and fire the piss out of it.
karen terpstra, from la crosse, wisconsin has build her own
anagama, and is now doing it again, twice the size.
she knows what it is about.
they are like the dock six women, get out of the way, and if
you don't like what i do....go to hell.
yet, eager to share, have good plans and systems in place...and get
on with it.
and with the crowd of people asking john neeley train questions, it was
great to have this source. a big thanks to them all.
my laptop had a crazy glitch in the nndbase, (nicknames) and sent my emails
attached with 5 or 6 names.
i think the letters i sent to clayart from iowa are stuck on some guys
computer that sells insurance or `make a million dollars a day on the net`.
that crap always happens when you are trying to hook to a hotel phone line.
have to dial 7 numbers, get long distance, then download/upload.
if any of you got strange letters, just smile with the rest of us.
nils is off with his golf team, (golf coach at linfield college) and is
behind in his teaching...so
we will not hear from him soon.
kurt and i will fire the train this week, so will send results..
got the phone line in at the cabin, so will send some information from there.

Mel- This thread had a distant familiar ring top it. A long time ago (we'll
leave it at that) I trained with a family of Japanese where we fired a four
chambered noborigama. During the couple of years I lived with the Kawais'
the land next door was rented to a University professor of Archeology from
Tokyo who's main study was ancient Anagamas. Under his tutelage we built a
large traditional Anagama according to his observations of excavated sites.
At the time I remember discussing the fact that a number of the sites
showed ancient streams coming into the kilns. We had a lot of questions as
to what this might mean. I felt possibly for the purpose of reduction. In
another sense it may effect the heat distribution in the kiln since the
water expands so rapidly in the kiln at temperature. When one adds a water
drip into waste oil it actually acts to atomize the oil and make it burn
more completely or at least more rapidly.
I can't really understand why you would want to put water into the kiln
before the firing though. I can see at temperature or when the firebox is
above 1000degrees C.
