When
I set up my studio here outside Ferndale, WA back in the 1980's, I chose to set
up with just a small stackable updraft gas kiln for my cone 11 firings. I had a
larger kiln that I brought out to the property, but I was reluctant to install
it inside the old cedar barn that I had restored for use as a kiln shed. While
I am eager to follow in the footsteps of potters such as Bernard Leach in many
areas, I have no desire to join him on the list of potters who have burnt down
the barns that housed their kilns. Once I had made the decision to go with a
small kiln to start, I found it easy to put off the building of another one
that would serve me better. When I started hosting Vince Pitelka's workshops
back in 1997, Vince was very complimentary about the work that I was producing,
but he was clearly appalled that I did not have more adequate firing
facilities.

First I had to clear the sod to prepare for the slab to
place the kiln on.

Thanks to his gentle prodding I finally was able to verbalize what
would be the characteristics of my "Dream Kiln" given the parameters
of my current studio and style of work. Once I was able to say what I wanted,
Vince set himself the task of designing it for me. He has been very helpful in
guiding me through the process of building this kiln myself. This has probably
turned out to be more of a project than he had expected though, since I was
determined that I was going to go through the process of getting permits for
the whole project. Whatcom County has a reputation for being among the most
stringent and difficult places to get permits to do anything, and a
"homemade" gas kiln that they classed as an "industrial
high-heat appliance" in a residential zone was not an easy thing to get by
them. There were essentially two different permit processes required. First the
"use" had to be permitted within my zoning, then I could apply for
permits to construct the kiln.

Base of the kiln is laid, a layer of concrete blocks.
|
The concrete blocks were capped with a layer
of patio blocks trimmed to make a continuous pad for the brickwork to come.

The first layer of insulating firebrick
insulation for the floor of the kiln.

The
summer of 2002 was given over to the zoning issue. I was able to get my
property classed as "Cottage Industry", a "Conditional Use"
that allows small scale non-intrusive commercial use of residential property.
Without such a designation I was prohibited from even having a kiln any larger
than the one I currently use. Now that I had dealt with the zoning issue, I was
free to submit plans for the new kiln, there was just one unexpected new
development. I found out that I had a brain tumor!

A second layer of insulating brick is laid for the floor.
|
Finally a third layer of bricks completes the
floor and the base of the walls.
|
It was at this point that my friend Jerry
Bajema began to pitch in, matching my effort daily for weeks now.

The tumor was diagnosed in December of 2002, and operated on in early January
2003. It was large, but benign, and recovery, though still not complete, is
expected to be nearly total in time. In the end I will have only lost the
hearing in my right ear. But for some months after the operation it looked like
I was going to lose my home and studio as well in order to raise the money to
pay the medical bills. I had insurance, but with a very large deductible. And
there were so many loopholes to get the insurance policy off the hook for this
and that it looked like I would have to cover the major portion of nearly
$100,000 in expenses. At this point the kiln plans seemed pretty remote, but
within another few months, things had turned around such that they seemed
imperative.

The first three courses of the walls set burner ports and
the flue opening to the chimney
|
We had to redo this to use the darker, denser
hardbrick throughout the inner course .
|
Now midway up the walls. You can see how
hardbrick is used at the level where flame will enter and fumes leave the kiln.
|

Insurance paid off for me not so much for how much they paid out,
but for the discounting of the original bills through their provider network.
So I could keep the house and studio and still had a little savings, just no
income while I recuperate. For the last several years I have been relying on my
occasional employment to clean up hazardous waste spills, primarily in marine
environments as my primary source of income. At this point it is not certain
that I will regain enough of my balance to resume that physically demanding
occupation. It now looks as though I had best be prepared to once again make
pottery my main income source. To do that I definitely needed more adequate
firing facilities. So the plan to build a new kiln was on again.

Brick by brick the walls grow higher. Here's proof that I
actually did some of the work.
|
Finally we reached the top of the side walls
where we needed to place this free floating angle iron that serves to hold in
the outward pressure of the arched top. The "arch buttress."
|
At this level the outer course of bricks had
to be trimmed to "inlay" the arch buttress, while the inner course
had to be trimmed to support the angled orientation of the first course of the
arch

Vince completed design illustrations in April of 2003, and I began
the process of getting the required permit. This process was very tedious and
drawn out, but so it is with bureaucracy. I was required to submit engineering
studies of both the structure of my kiln and it's enclosure, as well as the
combustion system. I was lucky to find a sympathetic and supportive engineer,
with both the required structural and mechanical licensing, who did the work
quite reasonably, and then purchased enough of my work to restore the capital I
would need to build the kiln. He was not alone in generously stepping forward
to help me out with this project. Many among my base of friends, family, and
customers have similarly responded, and it's only with thanks to them that I
can report progress in this area.

At last the bricks were ready for the arch. But first a
form had to be made to support the arch while under construction.
|
With the arch form in place the arch bricks
were built up in matching courses from either side.
|
Now that the arch is completed the wedges
holding up the form can be removed and the form withdrawn.

It
was late June by the time I was able to get all the documents and studies
together to formally submit my permit application. Then began the most tedious
part of the whole process. I simply had to wait while the bureaucracy mulled
over my request. Having had more than one plan fall through at this point in
the past, I didn't feel it would be wise to purchase any of the required
materials until I was sure I would be allowed to follow through. The wait was
interminable, but I did find things to do. Around August I found that I was
recovered enough that I could begin to work on the potter's wheel again. I
managed to refresh much of my old skill and even advance the evolution of some
of the forms I had been working on before the operation. At last, in early
September, the permit was approved.

|
When the arch form is dropped, the arch remains,
supporting itself now. It looks precarious, but you could walk across it.
|
Probably the toughest brick trimming job was
carving the bricks to fit under the arch and close the back wall.
|
Next the chimney had to be built up through
the roof.
|
|
|
|
|
|
Now
with summer nearly gone I was able to begin the actual physical work of putting
the kiln together. Lucky for me the dry days held on long enough to get the
slab poured and the carport awning erected so that I had a sheltered job site
to house the brick when it arrived. The first module of the kiln frame had
already been delivered, so on the 30th of October I finally started laying the
block for the base of the kiln. I see now that it's been just three weeks.
Construction has been carried a little further in that the welder has now
brought the frame for the car that carries the bed and door of the kiln on
rails, and I've spent the last three days working with Vince via e-mail in
Tennessee while travelling to Tacoma twice to get my burner assemblies
configured properly. I'll continue the story on another page as we brick up the
car and finish the plumbing. Boy it's getting cold!

Jerry was kind enough to do most of the work up on the
roof . Here he's laying the last of the chimney bricks in the angle iron
framework.
|
Then he put flashing material over the
exposed brick, and over the gap between chimney and roof.
|
Here Jerry puts the finishing touches on the
layer of castable refractory that covers the brick of the arch.
