Has anyone tried the soluable salts on stoneware that were in the September
issue of CM, by Kurt Wild? I had always wanted to try the metallic salts that
Arne Ase uses on porcelain, but didn't use porcelain and couldn't find the
materials. Finally, I asked Sayeed at US Pigment in Chicago about these
soluable salts, both those in the CM article and those in Ase's book. It turns
out that he carries most of them and they are reasonably priced. Anyone want to
do some mad experimenting? Most of the soluable salts were in the $2 - $6 a
pound range except cobalt sulfate which is 12. Chromium tricholoride is a
little harder to get. Sayeed is researching this for me. Anyone have any idea
where Mr. Wild and others might be getting these salts? Most of the materials
in Ane's book and the Ceramics Technical issue can also be gotten from US
Pigment, however, they have always been used on porcelain. Anyone else think
of trying them on stoneware? I'm ordering what I can to do the first round of
tests. Misery loves company so if anyone else wants to do this, let me know.

hi linda. yes, I read the CM article and am planning to try some of the
salts. Probably on porcelain, tho as thats what my focus is gonna be for
a while since i want to play with colors in oxidation, I teach chemistry
at a local communicy college so have no trouble getting most of the
chemicals i need. Expept perhaps the uranoum oxide thats on a tread just
now. So if you have ideas of salts that you cant get, drop a line and
maybe I can. Or try a test for you here. or whatever. anyway, keep in
touch and well see what materializes. I cant type in case you didnt
notice. I actually spell quite whell believe it or not. Chris

Linda,
Worked with soluble salts many, many years ago fuming salt kiln loads and
raku...also did a little fuming of blown glass. It's a great, somewhat
unexplored area. However, PLEASE get info on the toxicity of these materials
(MSDS from supplier and "Artist Beware" and "Health Hazards Manual for Artists")
BEFORE using them and READ IT.
Their soluable nature alone increases the hazards of working with them greatly.

Regarding the use of soluble salts on stoneware instead of on porcelain:
Having read the Arne Ase book as well as the recent articles in Ceramics
Technical and CM, I too want to try this technique - but don't work in
porcelain. I was able to get a number of the water-soluble colourants
(this is how Ase refers to them) from a scientific supply house in the
San Antonio area: Analytical Scientific. Ltd., P. O. Box 198, Helotes,
Tx 78023-0198 Fax 210/520-3344 Telephone 210/684-7373.
I rather arbitrarily chose to get: bismuth nitrate, cobalt chloride,
ferric chloride, zinc chloride, cupric chloride, acetic acid, potassium
chromate, phosphoric acid, and a tiny bit of gold chloride. I haven't
yet done anything at all with them, but will be glad to share
information/results with you when I do get around to experimenting.
