I am in the process of gathering information to build a soda kiln for my
studio use. I would appreciate any information and feed back that any one may
have. thanks in advance.

Alot of information on soda kilns can be received from Elizabeth Gulacsy at the
Scholes Library at Alfred University (NYS College of Ceramics), Alfred, NY,
She will put together many articles on Soda from their magazines and books and
send them to you.

I am interested in current data on how G-23's or K-23's, coated with ITC hold up
on the interior of a soda kiln (I will be using soda ash as the primary glazing
I would also like to hear from other potters firing soda kilns built of various
materials and/or using protective coatings (ITC, alumina, etc.) for data on the
how these various combinations hold up to a soda atmosphere. I am about to begi
building a ~24 cu. ft. soda kiln. The jury is still out on the combination of
brick type/coatings I will use.
One technique I have heard about, but never seen is this: The interior of a salt
kiln would be coated with Albany slip (remember that stuff?) prior to the first
firing. The idea was the Albany slip would glaze the interior, effectively(?)
sealing the surface from sodium vapor penetration. Does anyone have any
experience with this technique?
I would like to compile this information and will post it on my web site (to
include images, if available - I can scan them). If you have any experience wit
soda kilns, let me hear from you.

Nope, never heard of this one and I don't think I'd want to give it a shot.
Especially on soft brick. I think that the glaze would penetrate the porous
IFB's and would continue to erode them firing upon firing. The added sodium
would probably keep fluxing the albany coating until your kiln was a pile of
brown crud. I wouldn't try this on hards either BUT, you could glaze
various types of firebrick with albany or something similar and fire them in
a salt or soda kiln for many firings and observe what happens. I'd try this
first before I glazed the inside of a kiln. I think that you'd probably get
a lot of iron fuming from the Albany and have trouble with glaze and clay

I am in the final planning stages of building my new kiln. I have had the
slab poured and it is cured. The question I have is on the dimensions for
the kiln, they are : H: 41.5( before the arch ) W: 41.5 and L: 54. Can
someone email me with what they think the amount of bricks will be ? I have
come up with a #. Just want double check that I am in the ball park. The
kiln will have the first 5 courses in hard brick interior and backed by
k-23's. The remainder of courses will be K-26's backed by K-23's. Total wall
thickness of 9''. Not sure at this point what the rise on the arch will be,
kind of leaning toward standard rise, which would ad aprox. 9'' to kiln
heigth. Any input will be greatly appreciated. Thanks, Mark Knott

What type of roof are you going to use? Flat, cat or sprung?
You need to plot your walls. Bricks are 9" x 4.5" by 2.25"
I think it is 2.25. Get some graph paper and plot out your courses and
figure it out.
For the arch get a hold of an AP Green book with the specs for arches
with various rises. If you can't find one, send me your span, your rise
per foot and I can send you the plot of what bricks you'll need per course.

I am looking for a person who is an "expert" on building a soda =
kiln. This will be a kiln used by a large membership so it needs to be =
easy to fire. However it doesn't need to be large. Large enough to =
conduct a workshop consisting of 10-15 people and small enough for =
members to use on their own( of course in a small group firing). We =
would consider a kiln building workshop also.
thanks to all responses,

Matt Long does a terrific workshop , has designed a fairly basic soda kiln-
one that he actually uses. He is at the U of Florida in Gainsville - profile
and work were int the last issue of Ceramic Monthly.

You might check with Donovan Palmquist. I think he has a "Master Kiln
Builder" Ad in CM.
