Some Gurus may have more to say, but I remember in the late 70's when I
was a graduate assistant at Utah State, they were building the new Art
building and needed info on how to design the safety aspects of the new
ceramic studio. Someone came out and did a survey of our chemicals. He
was MUCH more worried about the chemicals that we didn't consider very
dangerous than he was the ones we ThOUGHT were dangerous and Nickel
Carb. was one of them. He said it was carcinogenic.

old Dan'l Rhodes writes (Clay and Glazes) that Nickel in very small amounts
makes grey colors, over 2% you can expect browns. He said it is mainly
useful for modifying (graying) other colorants, such as cobalt. The oxide
is evidently quite refractory and shouldn't be used in large amounts. (Not
sure what this means for the carbonate though)
I remember experimenting with it some in cone 6 oxidation glazes. Didn't
seem too promising. Other brown colorants are more reliable and more fun.
but perhaps others have unlocked Nickel's secrets...

Hi Ron,
Nickle carb is wonderful stuff! Mix vaguely by volume 1 nickle, 1/2 copper
and 1 titanium dioxide with water and a bit of the glaze you are going to
paint over, then use it as a majolica colour. It gives a beautiful appley
green, with breaking to brown. Great for leaves or whatever. Used in the
correct amounts, it gives the same colour whan added to a glaze. I just love
the colour.

Nickel as a glaze additive, either as carbonate or oxide is a fickle =
material. In large amounts it can have a refractory effect, seemingly =
reducing the ability of flux material to do their job of creating a =
glassy matrix so that the surface becomes dull, rough and brown. This is =
almost like devitrification.
The second point is that it can give a variety of colour responses from =
bright yellow, through greens to browns and tans to violet. Violet and =
blue colours come from small amounts in glazes containing Zinc oxide =
which might be a prompt for those people who are exploring the colour =
palette at cone 6 in oxidation firings. I also understand it does nice =
things with barium in the mixture.
Best regards,

Matt,
The "Ceramic Review Book of Clay Bodies and Glaze Recipes" contains
recipes with nickle oxide by the Indian potter Gouri Koushla. The book was
published by the British Craftsman Potters Association ISBN 0 9504767 2
2.
I don't use nickle, but I remember it only goes that horrible brown when
certain other ingredients are present.
Regards,
Bob Hollis
