...around 460 standard hardbrick.

Steven Mills design calls for common housebrick, but I
only used that for the floor.

46 inch chimney flue.
no dampers, do that with wood selection and stoking.

It "stalled" if you can even call it that for about 5 minutes
and I shifted the wood around and threw in some tobbacco
sticks to get the firebox excited again and it was over.

This thing just hits it. Stoke every 15 minutes for first two hours
and then go by the flame. Blast it at the end.

Primary air comes through the floor in this design and side walls of
the floor.

We were easily able to attain a 2 foot flume out the chimney,
but I know that is a waste of fuel.

This was really fun and educational.
I understand how people fall in love with wood firing, now.
I would still stick to paying the bills with electric, though,
in a rational business model. I know that David can hit it
every time, but I don't want that much variability in the
surfaces I paint on,my pots.

The pictures show the chimney kiln, the raku kiln, and
the new wood kiln/train in a tight little kilnyard.

The kiln can easily be fired alone if you have all of your wood
ready to begin with.

At cone 7 in 5 hours, by witness cones, it would easily do
10 in roughly 8 hours, by my estimation.

We fired the first firing by sight and feel and I know we hit
7 because of a "glaze cone", a glaze that I know melts only
and very reliably at 7.

My electrics pay the bills, but the kilns in the yard keep my
curiosity up and give me something to work out.

I don't need a woodkiln for the work I do for the most part,
but the plain wood effects are pretty
interesting depending on the clay body used.

Anybody here for the conference that would like to wood fire
that Friday before the reception,m is welcome to contact me
and I will set it up. And certainly if you want to stay a few
days late and do it then.

My only rule is that if you are not present for the stoking,
no pots for you!

(learned that the second firing when I put work in for someone
who was to show up late in the day to relief me and Drew, and
they did not show up.)

It was indeed a beautiful day, but if you say you are going to
do something, showing up is the first step.

I have so many options here now that it is
embarrassing. Now I HAVE to start workshops
on a quarterly basis, or these kilns will sit idle, and that
would be a crying shame.

Very nice! How many bricks of what grade did you use? Thanks, Donna

Steve will step in and correct me if I'm too far off but I think when
Steve and Kate demonstrated it at Aberystwyth, they did cone ten in 4
hours and the pots looked great. Steve does a very light, French style
salt using salt placed around the kiln in cups. Pretty cool!

This is a great little kiln, easy and cheap to build and easy to fire.
You can get the plans from Steve.
