gas kiln..build or buy?

Lisa Rich on wed 20 aug 97

I've been firing my work in a gas kiln at the studio where I take classes. I've
outgrown that arrangement & want and need my own gas kiln. I've looked at
catalogs of ready made kilns. I considered purchasing one of those portable
raku kilns that can fire up to cone 10 reduction but have been told by other
potters that these kilns really aren't able to handle repeated ^10 R firings.
Price and shipping issues re: the larger capacity kilns have caused me to
consider the option of building a kiln. I've ordered Olsen's "The Kiln Book".
If you've had experiences (good/bad, etc) with kiln building and can help me by
sharing your advice, opinions etc, I'd appreciate it. Thanks!

I built the 60 cubic foot MFT out of Nils Lou's book "The art of firing"
last summer. I followed the plans, and used firebrick seconds in order to
save money. One thing I did not skimp on was the frame, a local machine
shop did all of the metalwork for $700.00. Total cost including propane
burners (purchased from Nils) was around $4000.00 not bad when you
consider that a 60 cubic foot car from Geil would be around $20K.

I have had great results from this kiln, and after a short steep learning
curve, have gotten consistently spectacular results from every firing. If
you are building indoors, I would reccomend putting a fiber roof on this
kiln. Other than that, no modifications.

Best of luck...

Lisa,

If you can build it, it will be significantly less money (and
significantly more time). If you can possibly get a copy of
Nils Lou's book "The Art of Firing", do that. It is really
helpful, no matter what kind of kiln you eventually build/buy.

The book is not currently available, I think, but someone may
have one you can borrow, or your school library may have it.

Hi Jonathan

Just wondering why you recommend the fiber roof for indoors.

I'm planning on building the MFT from Nil's book next winter. We're
building the shed now. There will be lots of head room and I'm wondering
if anyone has built this kiln with walls and top out of fiber and as an
elevator kiln instead of as a car kiln. I would love some feed-back on
this--yes, maybe, dumb idea

Dhannon- I saw your note to Lisa about the kiln. I am wondering- would
you really think a person (such as myself or perhaps Lisa) who has never
fired a gas kiln alone or made one could properly make a working gas kiln
from instructions? The process seems mysterious and even potentially
dangerous. I just wonder whether a purchased gas kiln would make more
sense for a beginner.

If you buy or build... a CAR KILN is the way to go.... Your back and knees
will be eternally grateful... If you build your own kiln then you will
save about 500% of the cost of having a kiln in comparison to having
purchase one already manufactured... Just the shipping cost on a large kiln
is a thousand dollars plus... You can also inquire and some potters will
help you construct a kiln for a fee... ...Marshall

Leslie,

Where's your sense of adventure? I've never fired or built a kiln before,
but "Ah've always relied on the kahndness of strayngers" and my own two
hands, so I read alot, asked a LOT of questions, broke ground and
forged ahead in the pioneer spirit that made this country great (Battle
Hymn of the Republic begins to play softly in the background). Mistakes?
I've made a few, but I did it my way. In the process, I've had a lot of
fun, and learned a lot more about kiln science, plumbing, concrete, masonry,
and welding than if I'd just plunked down my hard earned dollars for the
finished product. Instead I plunked down my hard earned dollars for welding
classes, spray paint, cement, gas pipe, books, shipping charges, long
distance
phone calls, tools, bricks, and I don't remember what else. And I haven't
blown up the house or asphyxiated the neighbor's cat - yet! (Of course
I haven't actually fired it yet either, but don't get hung up on details.)

Get your hands dirty. Buy a welding hood, a paint respirator, a dry wall saw
and a fire extinguisher, and go get 'em!

Fiber roof spells problems as far as shedding fiber into glaze during a
glaze fire and also fiber will not insulate as well as IFB's... elevator?..
go car!...

Dear Mark,

I reccomended the fiber roof as I have had some problems with the brick
roof during heavy firing schedules. I like the idea of using fiber
modules as I think they will retain their shape better, and of course
won't seperate the way the bricks have.

As for the elevator idea; Why? The car design in Nils' book is easy to
move in and out, and is very easy to load. It is also easier to judge the
fit of the stacking with the roof and door right in front of you.

An elevator kiln seems like the mountain coming to Moses to me.

Leslie,

You know your own skills best. Some kilns are fairly simple to
construct, some are not. Start by reading what you can about
them, look for less-complicated plans, and think about it a bit.
If it seems beyond your capability or desire to build it yourself,
consider possible options. There may be an experienced kiln
builder who would advise you, or help you, or actually build it,
for a reasonable fee. But if you would be more comfortable buying
one and can afford it, then buy one. As I recall, one of the
issues here was cost - definitely less money to build than buy
ready-made.

Hi Sylvia,

I'm making one with fiber walls and top in next couple of weeks and will
post grim details if you wish. Whoever said it was time consuming was right,
but fun.

You will probly save a lot of money, but you will also go insane with
planning it. I have been planning mine for the past 2 months and now that I
am building it, it is just one suprise affter another. What I would do is
plan it out and then take a 3 or so day weekend and attempt to build it.

I just bought a copy of "The Art of Firing" from Axner. I think it was
$36.00 with shipping. 800-843-7057. I only needed a small kiln so we built
a 13 cubic ft. gas kiln using this book, and Daniel Rhodes' "Kilns" (we had
to buy that one used, it's out of print. Check out www.bibliofind.com if
you want a cheap used copy of just about any book), and a lot of
information from people in this newsgroup.

It cost us $750 with all new materials and a day and a half of labor. It
took a lot more effort to find local sources for materials. We've been very
happy with the results. Very glad we didn't buy one!

--------------------reply----------------------

Fred Olsen makes a good kiln kit, complete with instructions. Also,
good backup. A friend purchased a Olsen 24 and fires at least 6
bisques and three glazes a month. I have a used one which I put on a
flatbed with a forklift and drove across town to install. It survived
and has worked well for five years. Olsen is updraft. Might compare
to Geil which is downdraft. Geil does not make a kit. Their number is
1-800-887-4345. Fred Olsen can be contacted at Box 205 D.C. Mt.
Center, CA 92361 (619) 349-3291.

Hi Debra,

It's me again. Iso happens that we have a 24cu.ft. Olsen kiln in the
ceramics studio at Iowa State. We built it from the kit as a class project
for the advanced level students. It has worked so well that we've purchased
another one--an 18 cu. ft.--which is now sitting unassembled in the kiln
room just waiting for things to settle down a bit (our semester just started
Monday) See the ads for them in most, if not all, issues of Ceramics
Monthly. They are purchased direct. The frame comes pre-assembled, the
brick in boxes. Theyre quite easy to put together. In short, I highly
recommend them.

Regards,

Greg
