Thank you SO much for this post! I love the black pots that come from the
SW Indian culture, but there isn't a lot of collectible dung in Miami. All
the elephants are in the zoo, the llamas' owners are absentee owners, few
horse owners, no ranches for 100 miles. Fish dung isn't an option! So when
you tell me how to blacken pots by another method, I want to try it.
Thanks!

Consider asking the zoo for dung, I once had a potter who was also docent
at our zoo bring elephant, giraffe, and other dung to try in my
pit. Worked great for fuel but nothing particularly different about the
effect.

We get great blackware by smothering the bonfire with sawdust, and it smells
a lot better than manure. I still prefer to smother the fire with a mix of
dry manure and sawdust, but it is difficult to find dry manure around here.

Cow pies are used in many types of traditional-style
firing because they have 'structural integrity' and
a useful shape for piling around the pots. 'Road
apples' (from horses) aren't nearly as useful because
of their shape. If you're not doing a traditional
firing which requires stacked fuel, though, many
other things will work.

Do people in Florida keep rabbits? I've gotten some
terrific blackware using rabbit poop in a coffee-can
saggar. Doesn't take much, either.

I don't know, but I can find out if someone raises rabbits. It would be an
inexpensive source, I'm sure. I didn't know it doesn't take much. Do you
think I could save my dogs' poop--the lab makes a lot more of it than a
rabbit. (And my husband will be absolutely certain that I've gone totally
insane...)

Thanks a million!

Michele--

Have you thought about getting manure from a greenhouse or nursery?

No. But I wondered if getting a bag of manure (sold as fertilizer) from
K-mart would do. It's not "pelletized" but that might be a plus. Anybody
care to tackle that meandering idea?

Manure you buy bagged is decomposed, so probably wouldn't give you the look
you desire.

I recommend finding a stable within a reasonable distance (there has to be
at least one around there!) and get some of their manure. Most stables give
it away freely, as it is produced in great amounts!

You could do that. But if you are going to buy bagged manure,
you ought to go to a place that sells organic stuff. The
commercial "cow manure" or "sheep manure" are only a small percent
actual manure. The rest can be literally anything, the makers
are not required to state what is in there, they merely call
non-manure "inert ingredients." That does not mean that they
are in FACT inert. It only means they are not manure. Often
cheap "manure" is filled out with materials that manufactories
have to get rid of and are otherwise called "toxic wastes".
It is perfectly legal in the U.S. to do this - so they do.

NO! NASTY! Use herbivore poop ONLY!

Michelle -
Gardener's manure from K-Mart or a garden shop will not work, because it is
composted. In other words, it has already been oxidized through composting,
and most of the carbon is gone. It's just mineral-rich dirt, and it will
not produce smoke.
Best wishes -

Thanks for the explanation, Vince. There's a reason for the odor--there's
good stuff still in there. Back when my family in Kansas had the compost
heap, we didn't think it was oxidation. We just called it stink! I guess
now I'm a DungHunter (huntress?)

Eyebrows raised, big question mark over my head...."Oh, REALLY?" There's a
fascinating little piece of chemistry info...now I won't sleep tonight for
turning that one over a few times.

Thanks for letting me know before I had the bag full, a mad husband, and
neighbors with the White Jacket Squad number on speed dial.

Hi!
My question is a a result of the not clear assisting of my translation
tool.
If I use a metal can or pail that closes well with it's lead, or a kiln
shelf Do I still have to add ceramic fibber?, Or to close it with a
coil of clay?

In what speed I do the firing, like I do bisque or like glaze firing.
Do not tell me which switches to open or close, I have different system.
Thank you very much

I tried using cookie tins, these seal pretty tightly and I added a
couple layers of foil over the openinging (under the lid) to seal them a
bit better. I actually had trouble getting the lids off because of this.

In one cookie tin I put about 1/2 page of newsprint, in the other I put
4 splinters of very thin crate wood about 5cm long each. Then did my
usual firing to 500c at 50% (that's the kind of controller I have). It
took about 3 hrs (1.5 up 1.5 to cool).

I don't know how much smoke escaped (I have an Envirovent) I wasn't
there but I doubt that it was much if any at all. There was so little
combustable in the cans.

Got BLACK, as expected.

Only thing I would change is to fire the cookie tins on their own first
to burn off all the paint.

Anyone have an idea of the temperature limit of a cookie tin? I think
they're probably steel.

Another technique to add.
