Coincidentally, I received Dennis Parks' "A Potter's Guide To Raw
Glazing and Oil Firing" (mentioned by Milton in a post today) as a gift
last week. I understand that it is out of print, but I'd be glad to
copy and snail-mail specific pages or subject matter areas for
clayarters who might be interested. Personally, I have to learn how to
fire, with more consistent results, the kilns I presently have before I
start thinking "oil" or "raw glazing," or "single firing." But who
knows? Someday, maybe, and Parks' workshops are only a state away.

again, i think duff has hit one nail on the head.
you don't just dump oil into a kiln.\
there are many things to think about, and some
real important technologies to consider.
drip plates
atomizers
blowers
if you are firing a wood fired kiln, most
anything can be thrown in that burns after you reach
red heat. oil, meat, fat, corn cobs, saw dust, old clothes.
but, to consider using veggie oil as a mainstay.
well,
i would not consider it. unless you understand the process
of oil firing.
being frank, and understanding problems before they
occur is the role of the teacher.
many never listen...just run off and build whatever they
want. fine with me.
it is a learning curve worth working on. but i sure get lots
of brick, potters wheels and tools from folks that quit.
oil has always been problematic.
many industrial kilns fired with oil, coal, wood, sawdust.
\all have their place. but engineering is essential
to great firing. it must be considered and learned. (before you
light the kiln.)
as i said the other day.
if you mis/fire half your kiln...you are not an ecologist.
you just wasted a great deal of fuel for nothing.
it is to be considered.
understanding your fuel is the most important part of any kiln.
kilns are boxes of bricks. fuel makes it work, along with some
basic understanding of thermo dynamics.
no free lunch.

mel,
No one said anything about dumping oil into a kiln. I used drip burners
and Kent and others use the waste oil burners. There is a lot of
technology in the burners.
I can be done and is being done everyday.
I have to say that I completely disagree with your statement: "being
frank, and understanding problems before they occur is the role of the
teacher."
Helping people along the path of discover is the role of the teacher. And
the teacher has to know when to get out of the way. Imposing your
prejudices on students is not the role of the teacher. You are sounding
like John Hesselberth who is warning against learning the Currie method
because it doesn=92t conform to his views on stability.
Real learning, innovation and discovery always scare the false teachers
because it threatens their position of authority. Let them run and
discover and then they can be the teachers!
You know that they told the Wright Brother they couldn=92t fly.

Most noborigama still being fired in Mashiko, fire off the main firebox wit=
h
compressed air kerosene burners and only put wood in the climbing chambers.
Burning with wood makes much or more sense than burning vegetable
oil (veggie oil is probably more effective in in diesel engines.)And
currently, we cannot used recycled wood to power petrochemical engines.
Never the less, experimenting is a positive thing to do.
