I've posted this recipe before. It's taken from The Ceramic Review Book of =

Alumina Hydrate 2 lb
China Clay 8 oz
TWVD (Ball Clay) 4 oz
Grog (80's) -dust) 4 0z. "Mix to a pastry-like consistency and roll into ba=
lls or sausages. Useful for certain lid fittings and especially for firing =
'rim to rim' - these wads fire hard and come away clean."
It works. Can change amts easily.

For my wood/salt firing I use the same recipe both for wash and for
wadding: 50% alumina hydrate, 40% kaolin, 10% fireclay.
The process to make the wadding is simple - based on the approximate amount
I think I'll need for a firing, I mix the three ingredients together in a
bucket, add some water, and mix some more.
I'm conservative with the water, so invariably it's too thick and I add a
little more.
Now it's way too thin. &%$*#^$! I add another scoop of Alumina. Still to=
o
thin! How could this be?! I add another scoop. And another. And
another. This is crazy - I didn't add that much more water.
Ok, time to add a scoop of Kaolin. And another. Still too thin. Ok, mayb=
e
a little fireclay. Still too thin, but getting closer.
I continue to add smaller amounts of the three ingredients, hopefully in
something resembling the original proportions, until I get to a good
consistency. Sometimes it gets too thick again, and I have to add water,
which starts the process all over again.
When I finally get it right, I put a lid on it. I now have enough wadding
for my next 10 firings.

I've used something like this for wood and salt but with the addition of =
=3D
all
purpose flour. How much? Enough to when you are unloading you can break
them up between your fingers.

Doug- LOL- I know what you mean. One never gets it right because by the tim=
e you need to make wadding again- you've forgotten the lesson. If you had p=
ut in coffee grounds etc to burn out- it would get really nasty next time y=
ou open the bucket- another argument against that stuff
I use
1 Al hydrate
1 Silica
2 kaolin (have substituted fireclay)
Mix, then add a little water so that it makes rolly polly dough balls. Add =
a bit more water, mix well- have to really creep up on it from the water si=
de of things.
This wadding pops right off without leaving crap on it- unless it gets a se=
rious drip of glaze/ash cementing it on
