I use fiber insulation that I have a small sheet of, can't remember what it's
made of. It looks like a sheet of cotton. I tear off three small chunks and
place them under the pot to balance it and it does great.
I fire at cone 6, mostly oxidation until we get the gas kiln kinks worked
out. I have stilted work at cone 6, the ceramic ones with wire tips. The only
time I had a problem was when I stilted very round bottom pieces which rolled
over on the stilts when the glaze melted. Duh, what was I thinking?
Also, someone asked about how to apply the soda ash. I have only brushed it
on. I apply an oxide wash to a textured area, then wipe off the excess and
then brush on the soda ash wash to create a slightly shiny surface. I have
also brushed dark glazes into the textures, wiped the excess off and brushed
the soda wash over that area. So far there has not been a problem with the
wash and the glaze interacting. After I have 1-3 coats of the wash on the
pot, I wax resist that area and then dip the pot into a different glaze to
finish the pot.
I am no expert on this, only learned how to do this at one of Dannon's
workshops this summer at Michael McDowell's farm. But I am having a lot of
fun with it. Check out the article on Dannon in "Pottery Making Illustrated"
(think it was a two issues ago) to see the effects of the wash on some pots.

Just had the first wind storm yesterday as a prelude to winter. Blew off a
chunk of metal roofing placed on top of the kiln to keep it dry (haven't
sealed around the chimney yet) and also the kiln god placed on top. The
roofing was on the concrete floor of the kiln shed with the kiln god resting
on top, unbroken. Think this is one piece I'll keep with the kiln for it's
good luck.

Anji,
Pads, also called wads or cookies, can be easily made. Simply take about 3
and a half scoops of Kaolin and 3 scoops of alumina hydrate, mix in with
some water until it is a soft plastic consistancy. The high amount of
alumina with resist the soda, and fall right off the pot after firing, also
leaving nice decorative circles where the flashing did not occur. To apply
these to the bottom of the pots, take three or four small balls and glue
them to the bottom of your pot with elmer's glue. Then turn it right side
up, and press lightly to level the pot and flatten the wads. I've also
seen these wads pre-cut from coils and bisqued, and set on the kiln shelf
under the pots, or hot-glued on. This is common and required practice for
salt firing, and the effect of the soda ash is somewhat like a saltglaze.
Question: My professor told me that the soluble soda ash will leach into
the clay body and flux it, causing slumping on fragile forms like wide
bowls and plattes with ring feet. Any experiences of slumping with the
soda wash?

Hello, all.
Just a quick question. I had gotten the impression that this soda wash for
artificial flashing was a reduction process, and so hadn't paid a lot of
attention as I haven't the capability to fire reduction (yet). Was I right?
Wrong? It would be fun to try if it can be done in oxidation.

At the risk of sounding unbearably stupid, what is soda ash? Is this your
lingo for sodium carbonate (Na2CO3)? I have used sodium bicarbonate -the
common, cooking kind - in much the same way. Or are you talking about
something entirely different?...
