When Mr Soldner gave a workshop in Charleston I met him.
He explained that he did not like deaired clay, it did not work for him--and
he demonstrated why he prefers sand over grog.
He made a coil from clay with grog and another clay with sand. When he
folded the coils into a bagel shape he pointed out that there were little
airholes around the grog pieces but not around the sand pieces. Tiny
pieces, tiny holes.
Now all you peepholes who published the body recipe WHAT CONE?

Dear Lili Krakowski,=20
You tell us "....When he folded the coils into a bagel shape he pointed =
out that there were little airholes around the grog pieces but not =
around the sand pieces. Tiny pieces, tiny holes."
Did Paul Soldner explain the significance of the size difference ?
For example, do larger fissures around fragments of grog cause glaze to =
penetrate deeply into the clay and become places from which brittle =
fractures can propagate? Perhaps porous grog extracts moisture from clay =
and reduces plastic strength ?

Greetings All--- Hi Lili
The few times I've fired with Paul in the kiln at Scripps College he hasn't
used cones.
One of the other participants in the firing asked him what cones to put in
and Paul got a quizical look on his face and asked "cones???" and shrugged
his shoulders.
He'd sit and watch the kiln and when it got to the color he wanted he'd
say ---"well, you guys can stay and fire as long as you want to, but it's
done everything I want it to do", and then he'd get up and leave.
For somebody like me, whose work tends to be characterized as "tight ",
working with Paul is a great exercise in being "loose".
If you wanted to nail me down though on the approx cone value of the firing
I'd say in the 09 -07 range. Some areas in the kiln were even lower.
Best regards,
