Nana,
You must throw little "half doughnut" dishes to stand on them the crystaline glazed pots. The inner circle fits the foot properly waxed, the concave area receives the dripping glaze. Later you must grind the foot to remove excess glaze. Throw many such half rings, bisque them and have them ready to suit your needs.
Crystalline glazes are beautiful and all care must be taken not to damage the shelves. Good luck and I hope you will experiment more in the future.

Hi all-
I work in a studio where classes are taught, and only certain glazes are
available or allowed. Previously we've had access to the following crystal
glaze recipe, but the new director has scrapped it because it drips on the
outsides of pots and sticks to the shelf. It also blisters sometimes.
Despite all this, a lot of us still love it, and I was wondering if anyone
could advise on how to maybe alter the recipe we've been using.
kona 4 feldspar 40.00%
whiting 7.83%
zinc oxide 24.35%
flint 24.35%
milled rutile 3.48%
Aaaargghh,

Dear Nana, What cone are you firing the recipe to?
regards from Alisa in Denmark

Why not just suggest collection trays under the pieces, like with
crystalline glazes?
Hope it helps,
John Britt

Crystal glazes work due in part to the glaze movement when the zinc &
silica get together to form the crystals. There's no mention of what
cone the recipe you wrote fires to, so it's hard to say what to alter
to achieve a glaze that wouldn't run, but with any change, it may
also lose some of it's crystal forming properties.
How about suggesting that anyone using this glaze must also supply a
catch plate for each pot?

Nana,
I think you will find that all crystal glazes drip and run, but as a director of an art center, I can understand why your director wants to minimize the damage. Kiln shelves are expensive. We have several glazes that run or drip on their own. we place a small clay tile which we call a biscuit under all suspect pots. If it runs, they get a free biscuit with their pots, if it doesn't, we use the tile again. Many folks also trim a foot that can collect drips and runs as part of their design.
I hope this helps,
Charles

Hi Nana,
Most of us crystalline potters use what is called catchers which amounts =
to a saucer. I use white stoneware with grog to minimize the shrinkage =
and it is cheap. You also need to fire your piece on a pedestal that =
sits inside the saucer. This elevates the piece and the run off glaze =
goes into the saucer and not on the kiln shelves. It is more work but =
it is just the process of the glaze. I hope this helps some.
