Hi Lyn,

Alumina and kaolin, fifty/fifty by volume makes great (upscale) wadding.
Unless you are firing a salt kiln or a wood kiln this is not necessary.
Kaolin and silica, mixed like clay instead of kiln wash will work fine.
You might add a bit of sand or grog to that mix, too. The alumina and
kaolin mixture sticks to NOTHING, and cleans up easily after the firing,
but the alumina is a bit expensive.

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

Thanks to all those who sent me techniques for attaching wad
to the bottom of pots.
Most methods ar very similar. Some make the wads out of a
stiff kiln wash type mixture instead of just clay. Most use
elmers type glue to attach.
>From what I've managed to glean and based on what I'm trying
to achieve, I think that I am going to try the following on
my next firing.
Make the wads out of kiln wash, I will put some alumina
hydrate in the glue and attach the wads with that.
Several people suggested treatments for the shelves. I'm
sure that the techniques would work, but I want that little
bit of vapor to reach the bottom of the pots, so I like the
idea of lifting them up off the shelves.

At the Southwest School of Art and Craft, we use a dab of vaseline to
stick the wads on the bottom of the pots for salt firing. It works
great. Wads are kaolin and alumina paste. Cheers!
