This is an album showing the ash glazes fired in the wood kiln.

We got cone 8 in 6 hours and then slow cooled. The glazes used in the albu=
m are fluxed unwashed ash glazes.

The images in the canteens are made with a PRESS, a stamping system that I =

Gary,

Thank you! I have been working towards achieving a look and true vitrifica=
tion and I think I have got it. I am very happy with the ash glaze and the=
procedure couln't be easier.

I think cone 7 wood is more rational for an individual studio potter workin=
g either alone or with a small crew, 6 or less. Especially for schools bec=
ause we fired twice in 4 days, and that was incredibly educational to fire =
back to back with a crit in between. But if you can't get the look at that=
temperature, there is no point. We got the look that is characteristic to=
me, the flashing and wadding marks. The pure ash glaze is not attractive =
to me, really, so it is not critical. Steve gets the pure ash glaze with j=
ust a couple more hours of stoking. And he loves it! So it has a lot of v=
ariability, and that is a big plus to me.

We had 7 down and were pushing past 8 in 6 hours! I use sawdust fireballs =
to make the blast most efficient. So I am stoking with one hardwood stick =
and one firebag every minute or two at the end. My kiln is modified from S=
teve's original plans. I had the old version and built from that, but it i=
s interesting that I changed the floor and side intakes in a way that he in=
dependently changed in his subsequent plans. My seat of the pants decision=
based on available 3 hole brick and a rudimentary idea about building a gr=
ate turns out to be the better way. I modified it quite a bit as we built =
it and after firings and that is really good. Building and firing this has=
been an education for myself in kiln design and firing. And as mel says, =
doing it is the best way to learn about it.

We stopped because we didn't want to take it higher. My plan for this kiln=
is to fire using the same materials as the rest of the studio, which is co=
ne 7-8 stoneware. Any higher than 9 and the whole kiln would have bloated.=
We got rich color and ash accumulation on several pieces in amounts that =
make them interesting for me but not "all about" the ash, if you know what =
I mean.

But the kiln can do it, Steve has definitely proven that. It is different =
from traditional wood and so the goal and the expected outcome should be di=
fferent. This kiln is managable for 1-3 people and a fun experimental kiln=
. It was a challenge to myself to build and adapt one for my area of the c=
ountry where the water table is very high and the wood available is very po=
or, making a traditional anagama or climbing kiln much less practical.

I can get about 40-50 beautiful toasty wood pieces out of it, too, so it is=
a reasonable size for a days work. So in the same 6 days of loading firin=
g and unloading of a traditional small anagama, I could produce about 200 p=
ieces of finished work up to 2 feet by 2 feet by 3 feet in size (the interi=
or ware chamber size). That is comparable in output overall.

I am getting the wood effect with the same materials. This is important in=
the experiment for me.

We were hitting a new cone every 15 minutes of stoking by the blast and Ste=
ve and I both thought that we could continue the rise with no problem.

I might take it higher some time, but I would do that with work without gla=
ze. We were accumulating ash pretty well at 8 (by the draw rings) and I wi=
ll probably do a firing with no glaze and see how it turns out.

I built this in 2007 and am just getting around to talking about it, but I =
have fired it often enough now that I am ready to share the results. I had=
to get to know it well first, especially because there are a lot of skepti=
cs about cone 7 wood, still. But I think I can defend this kiln well as a v=
iable option for studio potters. And the work will have to speak for itsel=
f.

Hi Gary,

Elizabeth's Kiln is well capable of exceeding cone 10, we had to hold it ba=
=3D
ck!!
It's just that all her glazes are in the 7+ region, so there was no need (o=
=3D
r desire) to go higher.
Maybe in the future, but the results she gets are what she loves, and as fa=
=3D
r as I'm concerned, that's good enough for me.

With my own one here in the UK we fire to 12 flat! but then that's where MY=
=3D
glazes are.

Keep 'em Smokin' Pal

Most modern fastfire kilns, if they are built properly, can hit cone
10 in 5 or 6 hours. The big tasks , like Steve mentioned, his
holding them back.

No! I am no recovering electric firer. If this kiln was not compatible wi=
=3D
th my cone 7-8 materials, I would have to ship, manage, and store a whole n=
=3D
other line of clay and glazes. And that increases your carbon load. =3D20

Electric firing has bought me a house, a studio, and a trip to china among =
=3D
other living expenses for 25 years, so I am sticking with the main money ea=
=3D
rner in my life. I did not need this kiln in any professional way. My prim=
=3D
ary expertise is chinese brush painting and it works best in oxidation. I =
=3D
have run some through the wood kiln, though, and gas, and it takes on an an=
=3D
tique affect that is lovely. The reduction mutes the color and draws up "n=
=3D
oise" in the paintings. It's all good.

The wood kiln is for intellectual and personal growth. I needed a new stim=
=3D
ulus and challenge while the boy got up to school age and I needed it at ho=
=3D
me, not an mfa-program commute away (ECU has a wonderful program but it is =
=3D
2 hours away and that is not compatible with raising a toddler-you adjust a=
=3D
s life occurs).

Also there are a lot of factors of higher firing wood that I am not wild ab=
=3D
out. They are what they are and that is good, but did not fit my long term=
=3D
needs or desires. Huge runny ash and gnar do not do it for me, and for th=
=3D
at sort of thing, I can always fire in Dan Finch's Mamagama, which does tha=
=3D
t really well and is two and a half hours away. I like the subtle, softer,=
=3D
warm, toasty, heavily reduced side of wood. Things that an electric kiln =
=3D
struggles with. I also like a light french salt, and that is not compatibl=
=3D
e with long firing wood.

It is like owning a truck and a convertible. I want both, but a convertibl=
=3D
e truck, while a novelty, would just be a bad truck AND a bad convertible. =
=3D
Because if I am hauling stuff, I don't want it to fly back up in my face, =
=3D
and if I want the breeze in my hair, I don't want there to be "garbage" in =
=3D
the breeze.

As it is, I have a complete set of 14 glazes that I have worked with for 25=
=3D
years that I know well and trust that now have a whole new look. One of t=
=3D
he ones that I 'never used' electric because of serious crawling issues is =
=3D
dramatically beautiful in this reduction wood fire. My gloss white behaves=
=3D
like a clean japanese shino, carbon trapping and all. During the two firi=
=3D
ngs, I had the 8 attendees use all 14 glazes, that is what all those bucket=
=3D
s lined up in the pictures were about. We tried everything and MANY combin=
=3D
ations including Coyote glazes and some raku glazes. If it melts, I am wil=
=3D
ling and able to melt it.

They fired on average 4 pieces a piece and I had 12 in and two from my stud=
=3D
ent who is deployed right now and couldn't make it. So 46 test pots and 18=
=3D
salt cups (coveted) makes 64 pieces of work. We only had one crawling inc=
=3D
ident and I am sure that involved glazing after lunch of pizza. We got an =
=3D
excellent range of glaze effects. The ony one I am missing is a copper red=
=3D
. But the iron saturate red is a personal favorite along with a green cele=
=3D
don.


The top is covered with a fiber blanket and a complete layer of firebrick w=
=3D
hen firing. That is a HUGE r-factor for the top, where the heat escapes th=
=3D
e most. The sides are designed to breathe. The firebox is twice the size o=
=3D
f the ware chamber and heats from below and through draft, so heat is not a=
=3D
problem. For accumulation and debris, I can fire it down or fire it longe=
=3D
r. It is a choice to fire it to just the right spot.

Steve, who has fired this style kiln all over the world verified that it co=
=3D
uld do the other and his experienced opinion is good enough for me. Workin=
=3D
g and firing with him was a treasured experience for me. It took some arra=
=3D
nging since he is from the UK, but we seized on an opportunity and I got to=
=3D
fire the kiln with the initial designer of it, twice. He showed me how to=
=3D
fire it more efficiently, and I am confident now that I could land at any =
=3D
site and have one built in one day and firing the next. That is a good fee=
=3D
ling and worth the three years of work outside the box. (And no daycare fo=
=3D
r the 4 year old, so we all win as a family.)

Fast is good as long as the result is good. It is not a look-a-like as muc=
=3D
h as a whole new look. And its firing range is earthenware to cone 12-13, s=
=3D
o it has versatility as well as ease of firing. I think you can tell that =
=3D
I love my kiln, huh? We should all love and respect our kilns. If you hat=
=3D
e the way you are firing, how can you love your work?

The best universities are trying it...mainly with kilns designed to work hi=
=3D
gher, so they are having to adapt them. This kiln is designed to do this. =
=3D
If you have two days to spare, you are welcome to come fire it! =3D20

That goes for anyone with time for a visit to the beach. A 2-day wood work=
=3D
shop is now a fun addition to stuff to do here in the Beaufort studio. We =
=3D
filled this past workshop with local potters that had seen my experiments, =
=3D
so I didn't advertise it past an announcement on Clayart, but I can organiz=
=3D
e one for any group of 4-6 people that want to learn about it. Our brigade=
=3D
only had one experienced wood-fire person, all the rest learned on the fir=
=3D
st firing and then fired it themselves for the second. Steve, his wife Kat=
=3D
e, and I just held back and let them do it. I stepped in for one technical=
=3D
problem with their sawdust bags, but that part of the workshop was all abo=
=3D
ut letting them learn by doing. I did throwing demos on a York wheel, brus=
=3D
h painting demos, and just enjoyed the people and the day. That part, the =
=3D
communal firing, is still true of this kiln, if you want it. And if I want=
=3D
to fill it with special work for a show or project, I can easily
fire it by myself.
