I use a Laguna Clay cone 5 BMIX.

I recycle all my clay and don't know why this particular one begins to stin=
k
like a sewer. Is there any thing I can do about it
while sitting in the 5 gallon pail waiting to be dried??

Thanks

Hello Verna,
I use b mix ^ 10..
same problem.. i think the stinkyness is from organics fermenting,

which for your clay is not a bad thing, but for the potter, eww
stinky..

in my studio it probably is mostly fur (both cat and dog)
now, a drop or two of clorox will cure the problem.

Oh and most of that stink is from anerobes (that is bacteria that
doesn't like air)
So frequent stirring helps also.

Probably not while sitting in the pail..... but if you get out if it, you
could add a touch of bleach to get rid of the smell.

A little chlorox added will hold stinky at bay for a little while, but
bacterial action will eventually overcome even the anti-bacterial action
of chlorox. I don't think anything lasts forever in the way of keeping
clay stench at bay. On a positive note - that bacterial action - if
allowed to continue for 90 days - will give you some really nice
workable clay. The aging action on the clay by the bacterial is like
that of aging a good cheese. The longer the better. Some people keep it
for months in and old deep freeze or refrigerator. I've a friend who
puts his in 5 gallon plastic buckets, snaps on a lid and then buries the
bucket in the ground until a year passes, then will dig it up and pug
it. Makes for really nice clay. Some even pee in the bucket to enhance
the action of the bacteria. It sounds gross - but it works.

When I make a batch of paper clay, I add about 1/8 teaspoon of copper =3D
carb
or sulfate and this takes care of the mold and smell for a very long =3D
time.
That small amount in a bucket of clay doesn't seem to affect the color =3D
in
the end, IMO. Seems to me the same proportion may get rid of the mold in
your clay.

Dear Verna:
I use B-Mix as well. The one time my reclaim clay stank, as you put it, =
=3D
like a=3D20
sewer, I (eventually) found a decomposed piece of chamois in the clay....=
=3D
Not=3D20
sure if that is what is going on with yours, but perhaps something fell i=
=3D
nto the=3D20
clay that has now decomposed.=3D20=3D20

I'd have a bit of a "dig" through the clay to see if you can pin-point th=
=3D
e "bad"=3D20
area or find the item. It will be black like mold and smell really bad..=
=3D
. Just dig it=3D20
out and the rest should be fine.

I now do a "head count" of my chamois before finishing work for the day..=
=3D
. ;-)


All the best,

Miri in PR

In recycled clay, you often cannot pinpoint a specific source. Remember
that recycle clay contains skin cells and whatever else ends up in there
accidentally. Organic activity happens in clay all by itself without us
adding anything, and eventually will create that ripe sewer smell. For man=
y
potters, that's not a bad smell at all, because it means that the clay is
going to be very plastic.

We mix all our own claybodies, and among them is a recycle clay made from
all the scrap from our regular cone-10 clays. Generally there is no proble=
m
with any strong odor, but sometimes we cut into a log of recycle and it wil=
l
be dark gray inside and will have that ripe smell. It doesn't bother me,
but I can certainly understand how it might be offensive to some people.

Dear Bonnie Staffel

Thanks for the idea of putting a couple of grams copper sulphate into
batches of clay to prevent mould. I will try this to get rid of the black
rind that develops as my clay matures.

However I may have to put up with the less slippery clay surfaces that Tig
Dupre speaks about.
