Does anyone know what and how to make wads to
put under pots and kiln furniture to stedy them
when firing? I think you use alumnia and something
else--but I don't know what and I don't know whoskdf
how muxh much. I've seen them used in ^10 firings-
I fire to ^6. Anyone??? TIA

Flour is the other addative, mix to a paste and extrude through an old
icing gun.

Lyn,
So far as steadying kiln furniture: I personally just grab a wad of clay
(porcelain) about the size of ... ummmm ... a large marble, smash it fairly
flat, roll it around in sand so it won't stick to the kiln posts/shelves put
it on top of the post and keep on loading. I used to wonder about it
exploding since it's necessarily a wet piece of clay but they never have. I
fire fairly slow to cone 6/7, 12-15 hours to get there.

Lyn,
I use this mixture by volume for postwad...
1/3 fireclay
1/3 kaolin
1/3 grog
Just roll a small ball and set it on top of each kiln post. When you
unload the kiln, gently rock the shelf before lifting. This will break the
wad free and keep the post from sticking to the shelf as you remove it. If
you don't do this, a post may fall off the bottom of the shelf and damage
one of your pots.
It also works well for cone packs, I make them right as I am loading the
kiln and they never explode.

I find that wadding furniture is best accomplished with small "coils" of
50/50 Silica/Kaolin rather than using WADS, Balls, or chunks. It
stabilizes the furniture better in my opinion. The coil is put into the
shape of a small circle....about the diameter of the kiln post/soap/
brick/whatever....and placed horizontally on the post.
Porcelain probably works....but won't remove as easily...later when
re-stacking. Kiln wash and wad mix are very similar.....could use the same
stuff....just cut down on the H2O. ?

I keep a bowl of dry kiln wash (50 kaolin/50 flint) near the kiln. It's my
"flour bowl".
To wad kiln posts and level shelving while stacking a glaze kiln, I use my
regular stoneware claybody in the form of coils, "cookies', whatever it
takes, and dust them ("flour" them) with the powdered wash. It's just
enough to ensure release after firing.

Lyn,
The wadding that I use for atmospheric firings is this:
1 scoop fire clay
1 scoop sand
1 scoop sawdust
I have never weighed this out to find out what the measurements are by
weight. I have used this wadding in firings that were fired beyond cone
11 and have never had any problems with it. I used to use an alumina
hydrate and kaolin mixture, but I found this wadding to be much easier to
remove from the pots after the firing.

Last weekend I attended the Southern Highlands Crafts show in Asheville, NC -
IT WAS WONDERFUL - I met some delightful people who are WONDERFUL potters.
When I got home with my treasures, I noticed that one used wads of clay to
lift a cut lid from the base. I have no experience with this - do you allow
the wet clay to dry prior to firing? Do you add grog or something special to
the clay? Does it ever explode?
Thanks for any advice in advance,
Vicki Katz

I use wads to keep lids from sticking in the salt kiln. Sometimes they just
stick anyway! I mix equal parts by volume of alumina oxide and china clay.
Some people use alumina hydrate. I put the wads on between the lid and the
seat while the clay is still very plastic, just prior to loading the kiln.
The pots sit in the kiln overnight and I light early the next morning so I
suppose the wads dry out quite a bit especially in warmer weather. They are
so small that I doubt they would ever explode. I've never had one pop. I
did a firing on the 4th of July and I was hoping for one or two to blow, but
no luck. I had to break into my stash of black cats (fire crackers)!
