Fabienne-
Insboard is rigid fiberboard with temp ratings of 2300, 2600, 2800, and 3000
degrees. I believe the 2300, 1 1/2 in. thick is $70.08 and 2600, 1 1/2 is 122.22
for a 2 x 3 ft. piece. I got prices last week from John at Bryant Refractory Co.
Tulsa, OK, 918-446-1481.
It is a Harbison Walker Refractories Co. product. A sheetmetal shop could
fabricate a suitable enclosure for you to hinge. Someone with experience using
fiberboard could offer advice. I'm still in the planning stage. I do not see how
the metal on the inside of your lid would hold up very long.

Fabienne,
My friend's Bailey electric kiln has steel on the lid. I think you can
do the same. The fiber will keep the heat in.

Greetings,
I have been roaming the archives for ideas on using insulation on top of
the lid of my electric kiln.
The major concern is to keep the fiber from becoming airborne and from
falling apart when opening the lid. I was wondering if I could actually do
the following and get away with it:
- Have two sheet of stainless steel (like the jacket of the kiln) cut to
match the shape of my lid.
- Drill enough matching holes around their periphery to attach them to the
edge of the kiln lid with nichrome wire.
-Sandwich 1"-thick kaowool soaked in ITC 100 in the middle. I don't want
the kaowool to stick to the actual lid, thus the steel; however, can I use
steel in that fashion? If not steal then what can I use? Another concern,
does the kaowool with the ITC need to be fired? Questions, questions :)
Also, where on earth can I get the kaowool on-line? I tried a couple of
places, but no luck.
Thank you,
Fabienne who can't seem to find a thing tonight :)

A suggestion or two: Use sheet metal (same as duct work) - easier to work
with and less weight. You could have it shaped like a cap to fit over
lid/insulation. Self tapping metal screws can be used to attach to current
kiln lid banding. I have used block insulation (use similiar caution as
with kaowool when handling) You could attach kaowool with wire/buttons as
done with kiln walls and stabilize the kaowool with itc or similiar product.
This could be done on inside of lid. MarjB

> Fabienne,
The Mattech Corp. in Cincinnati, Ohio, manufactures
fibre free refractories tradenamed "Fractaball" and "Fractalins" which they
say can be used up to 2000 Celsius. You can get all details including price
from their website www.buyrefractory.com .

Curtsey reply: No need to do labor
intensive suggestion you describe. Simply cut a disk of ceramic fiber
(Kaowool is only one brand name of several ceramic fiber suppliers) to match
your lid, pin it into the lid with nichrome U shaped hooks (hooks can be flanged
outward, or grind a burr in the end to grip when inserted). Now
cut a circular rim the width of the top of your kiln wall with the same
material Pin it downward if you wish. As you lift and lower your lid
to "seat" on the lower gasket, it will not stick! You don't have
your bed blanket stick when you fold it upon itself do you? Same
principle!

Subject: Idea to Insulate Kiln Lid
Greetings,
I have been roaming the archives for ideas on using insulation on top
of
the lid of my electric kiln.
The major concern is to keep the fiber from becoming airborne and
from
falling apart when opening the lid. I was wondering if I could
actually do
the following and get away with it:
- Have two sheet of stainless steel (like the jacket of the kiln) cut
to
match the shape of my lid.
- Drill enough matching holes around their periphery to attach them to
the
edge of the kiln lid with nichrome wire.
-Sandwich 1"-thick kaowool soaked in ITC 100 in the middle. I
don't want
the kaowool to stick to the actual lid, thus the steel; however, can I
use
steel in that fashion? If not steal then what can I
use? Another concern,
does the kaowool with the ITC need to be fired? Questions,
questions :)
Also, where on earth can I get the kaowool on-line? I tried a
couple of
places, but no luck.
Thank you,
Fabienne who can't seem to find a thing tonight :)
