My Paragon is so old there is a huge red stripe radiating out from under the
lid when it gets hot. Smaller stripes between each ring. Gets hot enough
in there to push the peeps out. Anyway, I was thinking of wrapping a
kaowool blanket round the outside, but don't know
A. would this work? I think it would...
B. How could I cover the OUTSIDE of the blanket so I don't have fibers
floating around.
C. How to hook it together. It would not be able to go all the way around
because of the switch boxes and peep holes.
I saw the kaowool covered in ITC at NCECA and wondered if that was a good
answer, but don't remember if it was flexible.

Chris,
Do you know where one might purchase this insulation board? What does it do
at ^6? Sounds like it might be a good thing to put UNDER a kiln that is on
a wood floor.
Thanks. :)

Hi Lisa,
I just finished Monona Rossol's book on Keeping Claywork Safe and Legal. As
I already have some fiber around my old Knight kiln (mainly in the back), my
stomach sank when she stated that ceramic fiber should not be in the studio.
After discussing various studies and such she says:
p. 22 Unless you are prepared to do air sampling and wear moon suits,
ceramic fiber does not belong in your studio."
Yikes!!!!
I have often thought about just building (no mortar) more soft brick around
the sides and leaving the electrical box open. But I was afraid it might
cause the box to overheat.
Sincerely,
Nikki Simmons

Thanks for the idea. Don't know if it would work, since I have a sectioned
kiln. May try putting fiber between each ring like Frank told about his. :)

i think that it is going to be up to the potters
to insulate their electric kilns better.
i think this is another great area that clayarters can
lead the way. when you create better ways to
save energy with your electric kiln...well, let us all
know.
i have itc'd mine. have used kaowool blankets inside...
(bottom only)
kaowool blanket on the top.
i know i save energy.
bob anderson, uses a double bottom and a double top
on his gas electric. works.
this is a project to sink our teeth into.
we cannot whine about the manufacturers, we need
to lead them.
come up with ideas, post them. let people know/
track and keep records. you western potters have
a great deal to win or lose on this one.
it is like the person that fires the gas kiln for 20 hours
and says...`well that is just the way it fires`....
god, almighty do something about it.
i do not have a complete answer at all, need the help
of 3,000 minds.

Lisa,
I cut strips of kaowool the same width as the bricks and sandwich them
between the sections. Works very well.
As for the lid/lip area, I usually roll heavily grogged clay coils and press
into the crack right after I close the lid. Also, I used to cut thin strips
of kaowool and plugged the crack but stopped doing that as I don't want to
handle it more than I need to. I only have one kiln that is that beat up now
so hardly need to do it. The other five are new to almost new.
Frank, getting ready for final firing week. Hide razor blades....

Greetings,
I tried putting some of that thicker ceramic fiber; same thing I use to
seal the lid well but thinner. The fiber I use stinks while firing which
is a nuisance being indoors. By the time it doesn't stink, the glue that
held it together is finally burned out, but then I can't move it without it
shredding. Back to square one with stinking out the place. I gave up.
Is kaowool a bran or something different than the fiber? Does it smell?
TIA :)

Chris, where can I get some of the insulation board you are talking about?
It sounds just the thing I am looking for to make some small Raku necklaces.
I want to stick some Kanthol (sp?) wire to prop up the pieces, then put the
whole board full of ware in the post fire reduction. I am willing to pay.

How hot does the outside of a kiln normally get.? Would it be possible to
use the waterheater blankets to insulate them.? I dont think the glass-wool
would melt until it got to around 1100 degrees F..... If that would not
work.. it would work to wrap the kaowool inside the waterheater blanket and
secure it there..... and the waterheater blanket has a plastic outside
coating..so nothing floatin around........ Just a thought... Jim in
Denton...(when you get old you are permitted to have crazy thoughts....)
Paul Huel on sat 14 apr 01
Greetings,
My experience using ceramic fiber insulation on top of an electric
kiln(skutt) caused the finish that they put on the lid (reversible),
that stops the brick from shedding loose bits onto the ware to crack
off and therefore render it useless for using the other side. Anyone
else experience this?

Nikki,
You could spray the fiber with itc and it would be encased in it and be
safe.

>From some of the messages discussing adding insulation to electric kilns, I am
getting the impression that some are considering putting insulation directly over
the metal jacket of their electric kilns. I think it needs to be pointed out that
any additional insulation should be UNDER the metal jacket.
It is OK to add insulation directly on or under the bottom or the top softbrick.

I have a prebuilt gas kiln that cools too quickly. My father, who has
worked for the insulation industry for 35 years, has brought me home some
really unique insulation board. At first he thought I could use it in the
kiln, it did take the heat. But got a bit brittle at ^9. I've decided to
cut it up (4X8 sheet) and isulate the outside of the kiln between the red
brick wall I have around my kiln and on top as it is amazingly light.
Hopefully this will work and if it does I'll have him bring home more for my
electric. His plant is closing and he's scrounging bunches of interesting
equipment (the guys are making me a slabroller, three foot wide). I love
free stuff!! chris

To All:
Why not try a patch of fiberglass on the lid of the kiln since it is bare.
Next time you fire, measure the surface temperature of the lid. If the
normal air over brick temperature is 450 degrees F, addition of 1 1/2" of
fiberglass insulation might raise that to 900 degrees F at the
insulation-brick interface, but as long as the fiberglass doesn't melt ,
fine. Next time I fire electric, I'll try it too and report back and we can
all compare notes.
