We have recycled clay in 50 gallon plastic garbage cans at the center
where I teach. We use a wire handle off of a 5 gallon paint bucket for
a clay cutter to get clay out of the barrels. We had someone express
this same concern to the management (city) about the rust on that
handle. I think people get this idea from hearing about stepping on
rusty nails out in the ground.

As I will never get to do this, I throw myself on the curiosity of others.
The curiosity of strangers....

It has long been my belief, an instinctual one, really, that many celadons
and copper reds were achieved accidentally, through "dirty" water.

I have read that teensy amounts of iron in porcelain can affect celadons,
and I have seen (where?) recipes for celadon that demand a teensy amount of
red clay in the white body.

I also have read that copper sulphate (phide?) was achieved by putting bits
of copper in old wine casks, with water added, and the acid dissolved the
copper. (All apologies to the Ivans on the list who actually know the
technical terms. ) I tried that by putting bits of copper in vinegar and it
did work....

Ok. Now all of us are familiar with verdigris on the teakettle....So copper
does "dissolve" in normal circumstances.

My point is that I have a suspicion that if one mixes a porcelain body with
rusty water, or uses rusty water to throw with, and then to mix ones glazes
with, a celadon would be achieved. I don't mean rusty as in "Mommy, mommy,
there's coffee coming out of the tap!" but as in "Doesn't the water look
nasty..."

My suspicion also is that if one kept water in brass or copper tubs and used
that water to mix glazes, one would achieve copper reds....One might even
achieve them by slacked white clay in copper "vessels" (ooooh, she used that
word!) for recycling and recycling and recycling...

Why do I toss this out now? Because the times are parlous. But Spring is in
the air.

Hi Lily,
Very interesting idea, but rust can cause tetanus, and not everyone gets
tetanus shots [or any other kind] these days.

No, rust cannot cause tetanus.

This is an "old wives' tale". Rust does not cause any diseases in and of
itself. The theory that "rust causes lockjaw (tetanus) stems from the
prediliction of the bacteria that causes tetanus to inhabit the soil where
people and animals regularly travel; if you were to step on a rusty nail,
for instance, you would run the risk of contracting tetanus, not because the
nail was rusty, but because it may have been in contact with soil bearing
the tetanus microbe. Incidentally, a brand new nail can cause tetanus just
as easily.

Really, rust won't hurt you. You can drink rusty water, although large
quantities of it (tens of gallons) may introduce enough free iron into your
system to shut down your kidneys.

I do beg your pardon. Tetanus is not caused by rust. Tetanus is an
acute infectious disease caused by the toxins of a specific bacillus.
It usually enters the body through wounds, especially wounds which
do not bleed freely, such as puncture wounds; tetanus is most often found
in soil, it is endemic there.

I was not suggesting one scrape rust off in-use horseshoes. Assuming they
would rust on the hoof. My thought is that iron pots might be used as
throwing and mixing pots. I cook in iron, and sometimes the poits do get a
bit rusty between uses. Also I was thinking iron pipes.

As to tetanus: How can any potter NOT keep tetanus shots up to date?

Lily, Lily, :Lily, How could you allow your cast iron pots to rust between
uses? You must rub with oil after each washing, or the seasoned surface,
which you have worked for years to develop, will be gone and you will be
cooking on bare iron, as though your pans were brand new. I have cast iron
that I have been using for thirty-five years, and I would never let it rust!

Dear Rikki Gill,=20

<< but rust can cause tetanus, >>

From where on Earth did you get this exquisite piece of information?

Ivor.

I do not oil any but the stew pot. The others I prefer fat free--My frying
pans however are shiny--

Rust does NOT cause tetanus! Clostridium tetani, a spore forming bacteria,
is the agent. It secretes a neurotoxin which causes the symptoms after the
spores enter the body through a wound. The spores are most likely to be
found in soil and human and horse intestines. That is why if you get cut
with something that could have been in contact with soil it is recommended
you get a tetanus shot, initial or booster. Since I'm in contact with soil
(i.e. clay) I keep mine up to date- last I heard at least every 7 years or
if wounded with something really nasty. Since the bug prefers an anaerobic
(without oxygen) environment vigorous stirring of buckets should help. BTW-
I've never heard of a potter contracting tetanus from clay. Has anyone else?

John Rodgers on sun 30 mar 03


To further clarify what Tetanus reall is, and to dispell myths:

Tetanus occurs when a wound becomes infected with bacterial spores of an
anerobic soil organism - Clostridium tetani. These spores germinate,
multiply and produce a very powerful poison which affects the muscles.
Found especially in areas of livestock, the spores most easily enter
into the body through puncture wounds, whose character tends to be
anerobic, i.e., excludes oxygen, much like a needle puncture, except
more ragged on a micro -scale.
