just a few more details.
this will work, i believe, on any kind of stuck cover.
i used a spray bottle..and spritzed a small stream of water
into the gallery/cover area.
it sort of works like sweating a pipe...just fills right up.
it is less than a teaspoonful.
then set it in the freezer.
let it stay for about an hour.
take it out.
let the water unfreeze.
tap it with a wooden block. /and this one was a tough one.
you can tell by the sound when you tap it with a wooden handle.
when they are ready to break loose the sound is a bit of a rattle.
this one was tight. and, off it came...without any real hard tap.

I have an old wooden rolling pin that i use for this very purpose...
for a long time now I have put my casseroles in the freezer with a spritz of
water
as soon as i get them out of the kiln...I think this process has saved many
a casserole from
an overzealous tap that would often result in breakage.
It takes just a slight tap to make the lid release and I've learned the hard
way
don't ever tap right on the rim...move the wooden "tapper" to the place
where it can do the least harm
on the dome of the lid or nearest the handle where you have some extra clay
to
handle the stress.

Mel,
Thank you so much for these details - it'll make for fewer pieces of "yard
art."

I am thinking that adding water is an unnecessary option. I have only put
my pot in the freezer, then poured boiling water around the rim and lid, it
pops right off, the physics of heat expansion on the cold object. I started
doing this method about thirty years ago when I was making my special honey
pots. They were a dog to make and when the lid stuck, had to come up with a
quick fix.
I looked up stuck lids in the archives and found many, many old posts
regarding this problem. I wasn't even a part of Clayart as early as 1996
when Elca Branman posted the first one.

Hi Crew,
When I was 16 I took pottery class form "Jack" Foster at The Art School
of the Detroit Society of Arts and Crafts. One of his students was Huroko
Oba of Japanese decent. One day I noticed her immersing a couple of lidded
pots in a sink full of water untill the bubbles stoped and then

Thanks for that part, Mel, didn't quite know how to explain the sound of
one tap tapping.

Considering the physics involved in tapping pots with any wooden
object, a metal object seens a better choice. The wood absorbs a good
deal of the shock necessary to crack the offending bond. For years I used
a small brass turnbuckle with one end missing to tap free many a lid. Care
of course should be taken to avoid tapping too near the edge of the lip or
lid. I normally held the pot an inch or so off the table with the knob of
the lid which I think helped by preventing the table top from absorbing
some of the shock. Of course the tapping must be measured to avoid
breakage. This is a "first aid" treatment, something to be employed
before using some of the more involved methods already mentioned.
What do you say, Louis?

Interesting. I have moved towards a recommedation of hardwood. I would
think the same work is transfered roughly speaking either way although
probably less with wood. I don't know enough to make a firm statement.
Brass would just do it over a shorter time, a sharper shock, more force
in a shorter time. Makes me want to try a lump of lead as well. Does
not seem right though. I don't think it would work. As I see a dead
blow hammer comming at the pot I see it traveling right through the pot
with a big hole appearing in it.
Have you read "blink"?

Hi Louis,
Read of your recent travels recently. Sounds fun and inspiring. I have
not read "Blink" but it is on my short list. Hope the T-shirt is holding
up.
