Mel, if this gets gobbled up by cyberspace as my last three attempts
to post did, would you please post to the list? Thanks.
I'm going to be doing some ^6 reduction firing this semester, and I
started to wonder what would happen if I did an ^04 reduction firing?
I asked my teacher and she thinks the temp is too low for reduction.
I'm confused. Anyone ever try ^04 reduction? Or can reduction only be
done at higher temps?
Many thanks.

Certainly it is possible. I reduce at 012 for shino glazes. Raku
reduces at far lower temps than ^04.

RE the question:
The old Greeks did it, Deb, and so can you.
We're enjoying Joseph Veach Noble's "The Techniques of Painted
Attic Pottery," and we recommend it to all who haven't read
it. Should be available on interlibrary loan from your local
library. The Greeks did a cool trick with terra sigilatta,
reduction and re-oxidation you'll enjoy reading about.

American Raku is reduced at lower temperatures all the time. Some of
that, admittedly, just results in reduction of a very thin surface
layer and is subject to later reoxidation (e.g. metallic surfaces) but
some is very permanent and dramatic. I would think you would want to
start reduction before the glaze seals over to get the maximum effect.

John

In raku firing, the reduction (if any) usually occurs
after the work is removed for a post-firing reduction.
The level of reduction during the firing itself becomes
largely irrelevant.
