I know how dangerous shivering is, but I always wondered if maybe salt glazing might fix shivering,
assuming that salting wouldn't kill the finished pot.

Coleen -
I hope not. I don't mean to sound cavalier, but if you are talking about
genuine shivering, where razor-sharp slivers of glaze pop of the rims and
ridges, the only thing you should do with the piece is throw it in the
trash. When I was working full-time as a studio potter, I had shivering
show up on most of a kiln load in a 100-cubic-foot kiln. It really hurt to
dump that load of pots, but I had no choice. Shivering is just too
dangerous.

I was wondering if there were any good methods for repairing the damage to
a fired piece that has had bits of the glaze shivered off. Has anyone
tried to do this?
Thanks,

Kinda like putting a bandaid on a gunshot. Toss it and
make another with a glaze that won't shiver. Too much
liability.

Colleen,
I don't want to be a nay-sayer here, but a piece shivers because the glaze
is in too much compression...the piece has shrunk more than the glaze. It
will probably continue to shiver over time, freeing small, extremely sharp
and hazardous bits of clay/glaze that will present a potential hazard.
Shivering pots are scary to me. If you can't bear to discard it, I would
put it someplace where it can't cause any harm.
Best,

I have had some very limited (and unsatisfactory) results on terra cotta
mugs by refiring and cooling very VERY slowly, making sure to not open the
kiln until everything was completely cooled. Still had a little of the
problem, and ended up exacting a more lasting solution with a claw hammer
and a change in clay body.

No. There are not.
Is this a foodware piece, or something that gets used and
handled? If so, be aware that shivering is a condition of
bad fit between glaze and clay. The bits that split off of the
edges are just the current visible manifestation of a stress
that still exists within the piece. If subjected to additional
forces - hot soup or coffee, cold iced tea, knocking around
while being washed or just being used - more razor-sharp
glaze chips can come off, into fingers or food, or just onto
the floor where your dog will lick them up.
Make another one, and never use that clay/glaze combo
again!

I forget in which musical --is it "Annie Get Your Gun"?-- a character says
to another: "Stop your snivelin'; Wot you got a sleeve for?"
Well, what you got a garbage can for?
There are far more pots out there --no this is not an Etsy bashing--than is
good for any one of us. The pottery world is now full of the equivalent of
puppy mills--with exactly the same results. What once was valued is
becoming degraded, and "our" reputation as a profession is plummeting with
it.
If a pot comes off the wheel, or a handbuilt pot goes awry: do not try to
save it, reclaim it!
If the pot cracks in drying, don't save it, reclaim the clay.
If the pot comes out of the bisque with a defect, break it up and use the
pieces as test tiles. OR as moisture holding filler at the bottom of flower
pots.
If the pot is imperfect after glaze firing, and you cannot find a use for
it--such as oilpan when you drain the pickup--toss it into the trash.
I say this not out of cruelty. But simply that this is something one has to
do and learn to do sans tears. One has to learn to accept
that some pots will not make it. It is a part of what makes one a
potter--this ability to evaluate and judge one's own work. Just as many a
writer will have a wastepaper basket--or shredder--full of discarded
manuscript for every page that is kept, a potter will have a recycle bin and
a trash can full for every pot she keeps.
Toughen up!

Hi Ear,
What an interesting proposition!
I have never seen a salt glaze that is not crazed so it would stand to
reason that it might be an antidote.
The question is - would the salt get through the low expansion glaze to
reverse the expansion enough. Perhaps it would depend on the glaze
thickness.
