Can anyone tell me how to use ferric chloride with raku?
And please take a look, if you haven't already, at my homepage:

Dear Rick,
You take your raku piece out and let it sit for a few seconds. You usually
have clear or white crackle on the piece. Your waiting for the temp to come
down to 800 degrees or so. You just have to guestimate. Use a ventilator or
hold your breath because it's toxic. I can't tell you the solution
concentration either because I just add water till I think it's right. You
spray the piece when you think it's about 800. If you spray sooner I think
it just burns off. I haven't seen any adverse effects by starting too soon,
just that it burns. I just wait a little longer and try again in a few
seconds. Use as fine a sprayer as possible. If your sprayer drips you get
these larger spots that look like drips. I haven't seen anyone actually do
this. I had talked to Bob Smith at the La Quinta fair in Palm Springs, Ca
and that is how he does it. Mine aren't quite as nice as Bob's but not bad.
Have fun!
I had visited your web site and found out you are in Manitou Springs. My
sister is Marianne Flenniken and has a studio there at the center with you.
Good Luck,
Chris Kunze if you get a reply with more secrets that would be
helpfull to me in using f.c. please pass them on Thanks

I don't know if ferric chloride is similar to stannous chloride but I use
stannous chloride in raku. I take the pot out at the temp I fire to and set
it on a brick. I then sprinkle stannous chloride around the bottom of the
pot and "fume" it. I then put the pot in the reduction can. The stannous
chloride will create rainbow effects on the pottery - like gas rainbows. It
is critical that you use a resperator and protective gear as this is very
toxic.

PS I learned this from Gordon Hutchens from Canada - he has a video out about
his raku process - maybe its in there.

It's not only toxic! It's also etching. Actually, it's also used for making
etchings in copper plates. I've found the best spray bottles are the cheapest
ones. Fins a bottle with no metal parts in the nozzle, if possible, or else
it'll last for a very short time.
I used ferric chloride and stannous on white glaze.
And I also used copper chloride (cupric?) on the unglazed body to get vey
nice effects.

I learnt this from Richard Hirsch, who had a workshop here in Norway in -79.
After that, all raku potters in Norway were using chlorides on their raku...
It gives nice effects, but it's certainly one of the less healthy activities
you can have in a ceramic studio...
