I have a question. I have come upon a bunch of molds and some cone 6 porcelain
slip and wanted to know if I could try this for a raku workshop I have coming up. I of
course have some other pieces thrown and hand-built using normal raku clay, but I
was really interested in trying some of the mold shapes I have. I think they may be
real nice in raku.
Anyway, I have seen some info in the archives on not using porcelain for raku, but I
was wondering if there is anything I can do during bisque firing that would assist in
the pieces not cracking.
Any opinions would be appreciated, or if any of you have tried this I would like to
know what the outcome was.
Thanks!

I have often used porcelain for raku firing. I've
had zero problems with it. I am careful to put
a cold brick in to sit the piece on, and never let
it sit out in the open air after removing from the
kiln. Let it cool longer in the reduction bin
than you might cool a more
open body. I've not used slipware, but I have
very often seen it on raku pieces in commercial
pottery stores, so it works. Handle carefully,
try some smaller pieces first. And in any case,
there is no harm in TRYING something that you
are curious about. The worst that can happen is
a cracked/broken piece, and you'll have learned a lot.
