Another posting for a friend:

East Meets West Pottery has a 30-foot single chamber noborigama kiln
located in the rural setting of Walton, NY (3-1/2 hours NW of New York
City). It is availiable May through Sept. '99 for rental and/or as a
site for wood-kiln workships. If interested, contact Reinaldo (voice
mail) 212-726-8733, or Maxine Krasnow, 4027 E. Santa Barbara, Tucson,
AZ 85711, 520-327-3949

I think I'll be pedantic with this: As I undertand the terms, a single
chamber, hill climbing, Japanese kiln is an anagama. A noborigama is a
multi chambered, hill climbing, Japanese kiln. Both are usually fired with
wood, and nowadays for ash effects. Originally, they were not fired for
ash, but because they were the most efficient kilns of their day. That is
no longer true, so they are fired for ash, or for the romance of riding the
dragon.

Actually, there are quite a few people around firing noborigama with minimal
ash effect. It is hard to avoid lots of residual ash and flame flashing in
an anagama, since the firebox and the firing chamber are one. But with a
noborigama, the style of firing has much to do with the amount of
particulate ash deposited upon the wares. Also the firebox and throat
design can encourage settling of ash before it reaches the ware chamber.

Vince:

I agree with you on the distinction between the surface effects achieved
when firing an anagama and a noborigama. I might add that a kiln with a
Bourry Box is similar to a noborigama, as far as ash accumulation, with the
one exception being the "Train/Coffin" kiln.

From what I gather, Neely's innovative kiln design actually encourages the
accumulation of ash and flame patterning on the wares. I believe the design
element responsible for this is the large entrance flue between the Bourry
box and the ware chamber.

I'm currently constructing a "Train" at CVC. I have the floor and vertical
walls up to the top of the ware chamber complete. I just lack a few courses
to complete the firebox and chimney base. It's really a clever design with
the five primary air inlets above where the wood burns and with a tall
chimney to draw the air down to to the wood for combustion, then the flame
and the ash through the entrance flue, ware chamber, and finally the exit
flues.

My only concern at the moment is the top. It is a top loader and the plans
call for a roof of kiln shelves to span the 27" wide chamber and then two
layers of soft fire brick. I'm considering substituting those materials
with a roof of angle iron frame and expanded metal with two layers of fiber
attached and coated with ITC. My concern with that design is the durability
of the ITC coated fiber with regard to the heat, ash, and vapor.

If you want to know more about this design and are attending the conference
Neely is giving a presentation which I believe will include kiln design and
construction. Unfortunately, I'm not attending this years conference, but
look forward to the conference next year in Denver .

Actually, I'm familar with this kiln. It is more like a noborigama than an
anagama.
An anagama is an updraft kiln and the ware is loaded through the mouth
which doubles as the firebox once the opening is bricked up. In terms of
draft, the entire kiln can be thought of as an expanded chimney. Typically,
at the further end, there is a short chimney. The degree and length of the
slope will determine the height of the chimney.

The kiln in question is one chamber of a noborigama, which fires as a
cross/downdraft kiln. The design is based on a catenary arch, in which the
firebox is included in the chamber. In traditional noborigamas the firebox
is external, so this design represents a modification. But it has much more
in common with a noborigama than an anagama.

Wood firing also has notable effects on flashing of claybodies and slips.
Slipped ware fired in a gas kiln will be uniform in surface color. And
glazes fired in a wood kiln may look substantially different from the
glazes fired in a gas kiln. Wood kilns go up and down in temperature and
fluctuate from oxidation to reduction throughout the firing, leaving an
unmistakable effect on the ware. Some wood firers don't want a lot of ash,
others do. Kiln design, attention to the firing process and the stack all
have an impact on ash fall.
