Hi!
I have read with interest the posts on kiln wadding. I have never used it,
but have fired tiles on 1" kiln posts with varying success. I think that
wadding would be better, and more adaptable. Thanks to Craig for providing
his recipe. Do you make wadding made as you would make clay? Jean, does the
wadding release easily from your plates and platters after firing? Do you
others have wadding recipes that they would care to share for cone 10 firings?
I am always learning. Thanks, in advance!

Dear Paulette,
My wadding is just kiln wash mixed with enough water to make dough. Yes, it
releases; sometimes leaves a trace of white on the foot which is easily removed.
I, also, use this when shelves are not level at the point where the shelf support
will rest. I learned about making these little wads when taking a salt fired
workshop. Got home and said, "Well, why not also use them for other applications.

Hi Paulette
Just a quick reply to your post and the e-mail you sent directly enquiring
about the kiln wadding referred to in my books....

The wadding I use is about as simple as it gets... basically clay and sand.
The wadding should remain porous after the firing, easily removed even if
it's stuck on with glaze. So use a refactory (high temperature) clay, like
a china clay, or refractory fireclay or ball clay. The clay should be
reasonably plastic so that the wadding is not too crumbly. The sand is
there to open the clay and stop it exploding in the early stages of the
firing.... (because often we start the firing before the kiln wadding is
dry).
To make mine, I take some refractory plastic ball clay powder in a bucket
and put at least 30% sand by volume, mix dry (don't inhale!) add a little
water and work up to plastic condition. It's ready.
This is not rocket science... and hardly ceramic science! Just try some of
your ball clays and kaolins with sand (or grog), fire them to cone 10 and
see that they remain porous (and break apart easily) and don't explode in
the firing.... It should take less time to prepare several tests than it
takes me to write all this. :)
Regards Ian

you would like to purchase one of my books, go to:

or just e-mail me. If you pay for the books by credit card at my web site,
they usually take about a week to arrive.
Incidentally, the value of Australian currency is currently way down, so the
book price to you is also down. All prices quoted at my website are in
Aussie dollars.
