Hi Ingrid,
Hmmm, I can't find my reply to this, so i will send one again.
This is an interesting question. I have never approached raku this way
before, but I can tell you that I have fired raku pots a second time to
raku temperature when I didn't like the result the first time around.
The second firing just "erased' the crackles and surface effects from
the first firing, and the pots survived okay. I didn't necessarily like
the pots better the second time, though. That said, I know other people
who have re-fired their raku pots three or even four or more times and
amazingly, the pots survived, although each time they were more careful
about the water part and didn't dunk them, only sprayed them, if
anything, or let them cool in the reduction cans. Also, I have seen
people try to refire raku pots and the pots have cracked the second
time.
So I suppose, in theory, this could work. But it would be a gamble that
they would not crack or just go to pieces. Or they could be wonderful.
You'll have to try it and see, and let us know if it works.

Stacy,
I am by no means an expert, but when I first started Raku I fired with a
friend at his home. I tried pre-firing my pieces in the electric kiln an=

it was quite successful. However, since the glazes were already melted a=
nd
shiny, I would put one piece in that was freshly (raw) glazed as a monit=
or
piece. It worked quite well the few times I did it.

Subject: raku firing twice ?
Hello,
who has experiences with firing raku twice ? I have, quite rarely, the
opportunity to fire raku. To get as many pots as possible, I wish to
prepare them as well as possible. So I consider to glaze them (with my
raku-glazes) and fire them in my electric kiln at home,letting them cool
down in the kiln without putting them in a ton - like "normal" pots. So
they are better transportable and I don't need to spent time during my
"raku-days" with
mixing the glazes and putting them on the pots. During the raku- process =
I
would once again fire them and then put them into the ton and so on. Does
someone know whether this procedure is possible? Or will it cause
variations in the glazes or the crackles? And can I glaze and fire them t=
he
first time eventually at a lower temperature as necessary to melt, for
example at 900 together with new pots? I would be very happy, if someone
could
help me to avoid own bad experiences.
Ingrid
