fumes from new coneart kiln fired empty

Dear Friends,

I am Allen Steen, a new subscriber. I am fairly new at
pottery, and look forward to interacting with all of
you.

I am the proud owner of a shiny new Coneart 12 sided
kiln. I fired it last night for the first time and
noticed a strong odor. It was not ceramic fumes,
because I fired it empty.

Do any of you know the source of the odor? I'm
thinking it might be the insulation.

My cats have an aversion to the odor. Is it anything
to be alarmed about?

I appreciate your time.

Thanking you in advance,

Allen

Allen,

The kiln will not have that odor again. It is a first-firing odor. Some
companies fire once in the factory to get rid of this, but not all do. You
should vent your kiln, however. Really. If you have it inside, you *need* to
vent it.

Much of the fumes or smell is from oils used in coiling the elements
which will be gone after 1st firing. Take heed in what has been
advised about venting the kiln.

Guess and guess only. It may have been the calcination of some material
in he kiln itself. Cats hate all kinds of odors, some toxic fumes, some
smells we kinda like (test your cat on good gin) .

my guess is that on subsequent firings, it will be ok. NEVERTHELESS CALL
THE MANUFACTURER AND ASK! What can you lose?

Hi Allen,

The same thing happened to me last year with my ConeArt. Most of the smoke
will be over with this first firing; the second will have a bit less. On
the third you should be home free.

I was advised not to be breathing this stuff if I can help it; not that I
like the smell anyway :) I did my firing in the heart of winter and had
all the windows opened; the vent cannot pick up that smoke because it's not
coming directly from the inside of the chamber like other firings rather
from between the brick and the insulating fiber. You should find a nice
black ring on the edge of the underside of the lid when you open it. Nasty
stuff.

I was told that it's the smell of the compound used to "glue" the fiber in
place while they are putting it together. Why they don't do the burning at
the factory since most of us are not equipped to handle that amount of
smoke safely is still a mystery to me and a nuisance frankly. The other
thing, those manuals mention smoke, but it just doesn't hit home hom much
of it until you see it. They should say "ludicrous" amount of smoke not
just smoke in there.

I also use cut out pieces of fiber to the size of the upper bricks to keep
the lid tightly shut and every time I have to replace it with a new piece,
beware of the smell.

Good luck,

Fabienne

Yes, I have learned from my mistakes...
I can reproduce them exactly.

Call the manufacturer maybe but look in your documentation first. It may be
lubricant used on the wire when the elements are made.
