>anyone out there know how this should be done????
Dear Whoever; While teaching at Anderson Ranch BF (before fame, theirs), I
was building glass blowing equipment, melt furnaces, glory holes, annealing
ovens, etc, because the glass teacher didn't have equipment building
experience. Well, we held the just completed glass piece over a bucket
which held the metallic salt(silver cloride, etc) in alcohol over a gas
burner so the salts would fume up. The salt fumes struck the still red or
almost red glass which was then popped into the annealing oven. The result
upon cooldown was beautiful irridescence. Then we tried throwing the salts
into the salt kiln when it got down to dull red, result, beautiful
irridescence. Lastly, we adapted the fuming process used with the glass to
freshly pulled and lightly smoked raku, result, beautiful irridescence, at
least on the shiny surfaces. My favorite salt was Barium Cloride, which
gave a lovely gold to blue irridescence. Good Luck, Hank in Eugene
ps: There is probably some hazard to be adroitly handled with these perhaps
poisonous materials and their fumes.

Would you please explain what you mean by fumed copper raku. Fumed with
smoke or metallic salts or ? What does fumed copper raku look like? Scott

Thank you for your response....... Do you know if the same process will work
with clay....specificaly raku ????

I would imagine so-- the vital factor is a gloss glaze. It's common to
fume salt-glazed clay, using stannous chloride and sometimes other salts.
I've produced some very pretty iridescent salt-glazed porcelain using
fuming, but I eventually decided to move away from that approach, because
the layer of fumed metal is so thin that the pot can't withstand hard use.
I have a bee in my enormous bonnet about durable wares-- if they won't
stand up to machine dishwashing, I lose interest.
Since most raku is not intended for kitchen use, that wouldn't be a factor
for rakuists.

I've sent an e-mail plus attachments to Scott of an article (in CM April
1985 'Copper Matt Finish') describing the process and recipes to produce
'fumed copper raku'. Let me know off-list if you would like to have a copy.
Greetings from a misty Co. Clare...

I thought I had made it clear that the process works with raku; best on
shiny substrates(glaze), not as well on matt surfaces(clay).

I THINK THIS PROCESS SOUNDS WONDERFUL BUT WHERE DO YOU GET SUCH MATERIALS AS
BARIUM CHLORIDE, AND SILVER CHLORIDE? WOULD COPPER SULFASTE DO ANYTHING, CAN
YOU GIVE A GENERAL LIST OF THE (SALTS???) THAT YOU USED.
THIS WOULD BE MUCH APPRECIATED
THANKS

Hi; Try Van Waters Rogers nationally, or your local Chemistry Supply
Outlet. Try silver nitrate, ferric chloride, barium chloride, and watch
out! this stuff is poisonous. Hank

If your really interested in seeing how this can be done you should attend a=
Bob
Smith workshop. You should go anyway but especially if your interested in
learning how to apply ferric chloride. For vapor glazing with Stannous =
chloride
on stoneware and porcelain Biz Littell is the guy.

Hi=3B Try Van Waters Rogers nationally, or your local Chemistry Supply
Outlet. Try silver nitrate, ferric chloride, barium chloride, and watch =
out=21
this stuff is poisonous. Hank
Not only are they poisonous, Silver nitrate and Ferric chloride are also
corrosive. Wear protective gloves. Silver nitrate leaves nasty stains which =
take
a long time to wear away. And if no one has said so yet, wear a proper full =
face
respirator when you do this fuming so that your eyes are protected from the
fumes.
Best regards to all,
Ivor Lewis.
