Though I am not currently in your position of setting up a pottery to make
pots full time, I plan to be in that position within the decade. I currentl=
=3D
y
have my studio in a garage and fire in electric kilns. Having a place/space
for gas or wood kiln would be ideal.

Tony Clennell posted something on his blog about replacing his kiln damper.
Date is Monday, July 26. Blog: http://smokieclennell.blogspot.com/
There is a picture of his loaded gas kiln, a 24 or 32 cu ft =3DA0it appears=
.
This will give you a visual idea of stacking space in this size kiln. He
also has a wood burning kiln, but I don't know the size. Perhaps he will
post some information. He has been doing what you plan on doing for many
years. Look back for his post titled "3 legged stool".

Let's think about the end goal - selling pots. Will you sell from your
studio or take/ship pots to galleries? If from your studio in Maine, who
will buy the pots? Locals? Tourists? If tourists, what will they buy?
Large casseroles and big vases or mugs and small bowls - items they can
easily pack for travel? What is your production like? How quickly can your
make a kiln load of pots? If much of your production is smaller forms, then
it will take many of them to fill the kiln.

This is how I will think about what size kiln I install. It will be part of
the business plan.

Bill and Samm:
Firstly I wouldn't set out to feed a family from a wood fired kiln.
If I did I'd probably make it 100 cubic feet minimum. Economy of
scale. It takes just as long to fire a small one as a big one. I
believe Micheal Hunt (Bandana Pottery) fires 300 cubic feet in under
20 hours.
We fire our 30 cubic feet gas kiln every two weeks and the wood
fired kiln is our hobby kiln. Fired maybe 3 times a year for special
pots. After many years of firing like David Hendley you have some
predictability but in the beginning you will have less control, more
loss, more work, and winter to deal with. Covering wood, firing in the
cold, not fun!
The size of your kiln does determine the scale of your work. If you
have a big kiln you are more apt to make some big work to fill it. A
small kiln and you make smaller work or at least that is how it has
worked for us.
Have you ever fired a wood kiln solo? If you think you can call
friends up every two weeks to come over and help think again. Build a
kiln that you can manage solo or one big enuff that you can fire it
less often and with help.
gotta go clean my messy studio. Why I let it get so unorganized is beyond m=
e.

Sam-

Go bigger! I have a 70 cu.ft. crossdraft cat and it fires better with
less effort than my 30 cu.ft. did. I've fired it as fast as 5.5 hours to
cone 10 though 7-8 hours makes the glazes look better. I can fire it with
a truckload or 2 of scrap wood(i get it from construction sites.) I salt
it and it gives just a touch of ash. This kiln holds about 200 pots and
when I'm really killing it I fire once a month. I haven't fired it since
March, so that may give you some clue as to the state of sales here. There
are some photos of the kiln on my blog:

A lot depends on your experience with woodkilns. In the begining,
I would not build a kiln you only fire once or twice a year. If you
are as old as Tony or me, you might croak before you learn the kiln.

Build one you can fill at least once a month. Actually, if
you can, fire with others as much as you can before you build your own
kiln.

Brandon: Nice pots on your blog! Yikes you haven't fired since March.
That is a down economy!

Sam,
I worked on my own for 18 years, and my last production Kiln had a setting
area of 30 Cu-ft. I found it just right for a 3 week turn-round of orders
and stock.
Never keep a customer waiting!
