I have this nice iron glaze. There is some kind of
biological activity going on. It smells real bad.
What can you do to stop this? Thanks.

Does the glaze have bone ash in it?
That will often cause this kind of smell.
Ignore it or try some clorox.

When i first began to work with pottery, i thought i smelled "oil of
wintergreen" in a glaze. when i asked the craft shop manager if he put
some in the glaze, he said no. but the idea stuck with me, and i have used
this oil in old wax resist, that became smelly. it does mask the smell. it
might work in glazes too. PGBinky in cold san antonio, texas.

David,

I have to go with others that have suggested it's the bone ash (if there is
any in the glaze) . At Iowa State U, we used an Ohata Kaki and a Tomato Red
that both had bone ash in the recipe and both smelled to high heaven after a
while. We just lived with it, as the glazes seemed to work best when
"ripe".

David -
The saturated iron glazes all do that. Just enjoy it. Is the smell really
a problem?Don't add anything, because it could change the performance of the
glaze.

Hi, David.

Well, it's not the iron that's making your glaze smell bad. Does it contain
CMC, or any other organic substance? The smell won't hurt the glaze, but it
can sure hurt your feelings. People have suggested adding chlorine to such
glazes. This will kill the bacteria or other microbes which cause the odor,
but it may also cause your glaze to form PCBs, which, judging from Dr.
Bastarche's recent posting, you might wish to avoid.

Others have recommended adding essential oils of wintergreen or eucalyptus
(which would disguise the smell--maybe disinfect as well). Tea tree oil will
disinfect, but it smells as bad as the bacteria, or nearly so. If you do a
search for this in the archives, you may be able to find some of the many
pieces of advice which have already been offered. I don't remember what the
search parameters would be, though. Words you would expect to have been used
in the subject line of a post regarding smelly glazes, I guess.

When my glazes would smell, I'd generally have the privilege of fishing
a dead mouse out of the bucket. Poor little mousies would opt for a drink
and then slide........

I'm just going to call you Ed from now on. Bastarache, Bastarache,
Bastarache, Bastarache . . . maybe I've got it now.

I read that the chlorination of water had led to PCBs being introduced to
the environment. Of course, that was in the advertising literature of a
water distiller sales pitch, so . . . .

Anyway, I'm confused about what you mean by "not in the raw state"? What
would the non-raw state be?

Some of the iron red glazes I use have bone ash in them, which tends to
create "off" odors over time. I've just learned to live with them, as long
as the glaze is working.

try a small quantity of disinfectant, it shouldn't upset the glaze and
it should cure the problem.
