Diane,

Opening the kiln early is a no no. 6 hours after temp is probably bad. You
potentially ruined your work depending on the glazes and clay body. A slow
cool is best in almost all circumstances as it reduces the stress between
the outer skin of the glaze and the inner wall of the claybody as well as
crystal formation if you want that. If you want crazing, let that cool air
rush over that hot pot. There is an unfortunate chance that your pots
integrity is compromised. Test them when they come out. As a rule of
thumb, I don't unload unless my work unless my bare hands can touch the
pot--this was learned from unloading earlier and hearing the ping a ling
crack thud chrous of angry pots.

Thank you.

Wonderful to live vicariously as T. Sullivan
relates the fun at Nottingham. Wish we were there.
Rather we are here in sort of gloomy Ga., fickle
weather and yet another question.

We just did some rather successful ^10 glazes (based on
some John Britt ideas in Ceram. Monthly)...test in the
big electric kiln and they look great. We could not
wait the (necessary) 18+ hours to cool to look--we were
rotten and peeked after about 6 hours, a tremendous
no no
We see some fine fine crackles under the surface of the
glazes on some of the more "breaking" variety.
Is their integrity conmpromised, we ask???
I am aware we need to wait more like 24 hours for
cooling so that we have a room temp kiln unloading.

promising never to be so impateint
ever again...

Hi Diane,
Could you tell me please which CM the John Britt article is in? We need
some new ^10ox glazes at the Dubai Art Centre - you know, reliable, keeps
well suspended, is stable, strong safe, able to leap tall buildings...oh,
sorry. You know what I mean. Thanks.
Best regards,
Carol

Where I am teaching an additional two classes in the winter term but some
students don't know if they'll be pulled out of the ME next week or not.
"Should I keep throwing?", they ask. Of course.
