I have not done a lot of Raku, but one process I did try was to glaze the
work with a crackle white glaze. Pull the piece out of the kiln and as is
cools I spritz a solution of ferric chloride in water on the piece. It will
sizzle off until the specific temp has been reached, and suddenly the
solution causes an iridescent orange to adhere/develop. At which point I
spritz like a mad-woman as quickly as possible to cover the work in a short
duration of time.
Please note that the solution will stain concrete orange, so you might
consider placing disposable/unimportant metal under the spray area to
protect the concrete from the orange staining.
I have no idea whether stannous chloride does the same thing....
I purchase the ferric chloride from Tri-Ess Sciences, in Burbank, CA. It is
a business that supplies science materials to theatrical groups, schools,
etc., a great source. You can get formaldehyde frogs from them also.
good luck,
bamboo karen

Hi,
One question about this process-do you at any time put the pots in
combustibles to reduce?
Thanks,
Diane

Just as an aside. You can also get ferric chloride in almost any Radio
Shack. Ask for etching solution. And yes, it's extremely corrosive.

<put the pots in

This is what I know... If you put it on before you
post fire, it will turn a caramel brown.. If you
remove it from the Post firing let it set for ooooh 3,
4, or 5 minutes and then spray it on it will turn red,
almost as red as a candy apple.. If you reduce it I
have no clue what it does, because I got my directions
from Ramone Camerillo, and he uses the second
technique, I experimented with the first one and well
just plain haven't gotten to experimenting with the
reduction chaimber......
Is it obvious I didn't read any more then what Karen
said?? ; )

I have not seen the post firing reduction with this process.

All I have seen is a small amount of 'smoking', accomplished by placing
the pot onto a bed of paper or straw. The smoking colours the bottom and
part of the sides, but doesn't give what you would call reduction. The
results are very nice indeed, though.
