Just curious! Does anyone know how toxic it is to roast marshmellows and
hot dogs over the top of the hot Raku kiln? The pots are glazed with
Gerstley Borate, Frit 3110, Nephsy, and EPK for a crackle glaze and for
a copper flash a high percentage of copper carbinate is added. The kiln
is fired with propane. What do you think?

I wouldn't do it myself, esp. with all that copper carb. It may not
hurt you, but why experiment? Forget the mystique and use a barbeque
for the food! CNC

I don't think I would do that. The raku kiln probably is contaminated with
a variety of things, not necessarily restricted to what is in the glaze firing
at the time. Somehow, sticking an unprotected hot dog/sausage/marshmallow
over that flame and then into your mouth.....hmmm. Nope.

On the other hand, I have been known to stick a big wok over the opening
in the raku kiln for a quick stir-fry...so, six of one....

I think it is not good practice, generally, and I don't cook over it any more.
Sure did in grad school, though.

Speaking of marshmallows, they got both their name and their flavoring
from a little plant that grows in marshy places, called, SURPRISE, a marsh
mallow. Used to, anyway. I was purusing a book on Texas wildflowers
and came across that bit of esoterica.

Whoah!!! I'll be interested in responses to this post. I found when I rakued
in the patio, under a roof, that the fumes collected under the roof and
patio area and were not all good to breath. My body told me that. I now raku
in the open, and still don't stand around close to the kiln when firing, let
alone cook over the top hole. No idea how toxic or if it would infect the
food, but I sure wouldn't try it.

Your subject line says it all. Why even think about taking a chance?
There are enough carcinogens in the air that'll kill us without further
invitation.

Be well (and stay healthy...)

<<<<andhot dogs over the top of the hot Raku kiln? >>>>>>

As an RN, my first response is why? Although the risk may not be tremendous
(which I am not saying it isnt...), you are still dealing with fumes from
compounds which may be hazardous. Gerstley Borate isnt extremely toxic, but I
have seen precautionary warnings attached to it....as a health professional..I
say build a little fire next to your kiln if you want to roast food.

>I hope there is no fiber in the kiln? Not a good Idea! Hey but if you want
to, who am I to say? Just don't feed the food to children. Adults drink
alcohol and it is a poison, and you wouldn't give it to children.
logic: Adults can poison themselves, but not children.

As I recall, we have discussed burning "foams" before. =3D20

I do not know the composition of foam "rubbers", Styrofoam, others..but =3D
do recall warnings about their fumes.

IF you have ANY unknown substance do not burn it till you have checked =3D
Poison Control or similar. =3D20

As to cutting foam--an electric knife works wonderfully--as do saber =3D
saws.
