------------------
I have a Skutt 1227-PK (fires propped and w/a peep open to 500oC, then =
sealed,
unvented in an uninhabited drafty barn), fully sprayed with ITC, in which I =
have
successfully used silicon carbide in glazes for achieving local reduction =
reds
and celadons. True reduction takes some timing, and I don't want to open up=
a
kiln to put charcoal or drip in other combustilbles in at the right time. =
But
Nils Lou and Roger Korn have reported on drilling a single hole in the =
bottom of
an octagon kiln and putting a bunsen-burner sized gas source there with =
which
they have achieved reduction.

I was speaking with my friend Nikom today who told me something I found =
rather
puzzling but quite fascinating, namely that you can put whatever you want in=
an
electric kiln, especially newspaper and/or cardboard that you use for =
supporting
handmade work. I have always been under the impression that one must be =
careful
about burning off organic substances in an electric kiln because of the very
real potential to damage the elements. He said he thought that the concern =
was
unnecessary and that a reduction firing in an electric kiln is actually
feasible. Well, I have been considering spraying the kiln with ITC 100 to
protect the elements and he said that, if this is done, one surely could put=
in
just about anything with little or no concern to damaging the elements.

So, I need to know from some of you folks who have a good deal more =
experience
whether my new electric kiln can be used in a more versatile fashion by =
pushing
it towards a reduction firing. I do not have a concern for emissions as =
there is
a ventilating fan and I probably wouldn't be using the room while firing the
kiln.

Thanks for your help.
