Craig,
Reid Ozaki who did a lot of porcelain used to use an alumina wash on the
unwashed mullite or High Alumina kiln shelves when he was firing
porcelain. This kept the porcelain form sticking and causing small
chips in the foot. He would wash the alumina off with a sponge and
water. Then flip the shelves for the next firing. Reid would put a
ring of the alumina wash under the foot as opposed to covering the whole
shelf.
To make the wash put some alumina hydrate in water and made sure to stir
it when preparing to brush it on the shelves.
