celedon for woodkilns

Hello list,
I'm in a bit of a pickle. I'm looking for a nice celedon liner that will
fire well in a woodkiln. The recipe I've used for years that I got in
college runs at ^10.5, and since I've yet to build a woodkiln, all my glazes
are tweaked for the ^10 range.
I'm going to the Woodfire Conference in a week and just realized I don't
have a celedon recipe (well, any good glossy liner for that matter) in my
notes that I trust to be stable at ^11 or 12. I'm using Jiki porcelin from
Mile Hi.

Could anyone share a tried and true celedon with me? I'm desperate.

BJ,

Try this one. It won't run.

Great Basin Pottery Celadon (with a hat tip to old Bernard Leach)

Custer 40

Silica 36

Whiting 20

Grolleg kaolin 16

red iron oxide 1.12

I realize it doesn't add up to 100, but that's just the way it is in
my recipe book. It's a modification of the Leach 4321 glaze. I
regularly use it in wood firings here, inside the pot or out. If you
don't like speckles, ball mill it, and it will benefit from 1/4%
epsom salt.

I hope to meet you there in AZ, along with a lot of other folks.

Best,

Paul Herman
