flashing from glazes

i've gotten some flashing from one pot being close to another, and i got a vapour deposit transfer. this also seems to be involving - for me - a rapid cool down as well.

i had a kiln that was hard brick lined with cloth, and it would cool from cone 10 to "open the door" in 2 hours.

see ya

The 'flashing' effects that I have seen with oxidation firings has actually been done by applying multiple glazes with a spray gun. I have seen some pieces that look like they have come out of a salt firing. It is nothing I have tried though (I don't want to expose my lungs to more than they already have to put up with and I'm really just to careless to trust myself).

Would love to hear more if you come up with something else that works. Donna

P.S. You can fire in a saggar as you would in a reduction kiln with ingredients that will fume but I don't have any information on it - just remember reading about it).

I use two or three glazes to give a flashed effect. Spray on. I use first Nutmeg glaze that substitues the kaolin with Red Art spray it thin then in places I spray on a thicker coating of the nutmeg sub glaze. Then I use WoDo white to spray on over the thicker nutmeg sub glaze. Usually you want a glaze heavier in RIO for the flashing.

These glazes can be found in the ClayArt Archives.

Thanks to all for the replies.

Unfortunately saggar & multiple glazes are not what this potter did to get the flashing.

The designs were literally poured (with a single brown glaze) onto the pot and the orange flashing effect spreads onto the unglazed areas. I have photos of my piece which I had purchased and am willing to show if u e-mail me direct.

Any further ideas are most welcome. I'd really like to get to the bottom of this.

Are you sure it is not something like nutmeg, faux shino or Pinnell's weathered bronze green? I would not call it flashing exactly but where the glaze is very thin or on the edges of the glaze next to the unglazed clay you can get an attractive orange color. Why don't you post the picture on rec.crafts.binaries

I get this sort of thing on unglazed areas adjacent to one of my ash glazes, which I put down to my (deliberately) NOT washing my ash before making up my glazes.
