Gaye, Nickel is the most recipe dependent oxide of all. In one glaze it
can be blue in another green and in yet another red or pink. Hopefully
someone else can sent you the recipe for a spring green all of mine are
in these other shades.

Nickel with titanium.
I would add 5 titanium and 1-2 nickel to a glaze that has around 10 Zinc
oxide.

Gaye,
OOh! I think I just remembered the oxides I used for sping greeen, nickel, copper and rutile. You'll have to play around with the percentages but I wouldn't go over 5% with any of them.

At what cone? Oxidation or reduction? I don't think you get so much greens with nickel as you get tans and beiges but it depends on what other oxides you use with it. Copper carb will go green in reduction blue in oxidation. I have used nickel carb and rutile to get a nice banana yellow. Oh wait, hmmm I just remembered a chartruese glaze I came up with, did I use nickel and copper??? Don't have the recipe with me so I can't check. in any case I don't think you will get a spring green with nickel alone, you will have to combine it with copper or maybe even cobalt. Test test test!
Take care

Dear Gaye Sekula,
"Spring Green"..... "A variable colour averaging a moderate yellow
green that is greener, lighter and stronger than average moss green,
mosstone, average pea green or spinach green"..... (Webster)
An interesting proposition.
I suggest running a line blend with your proposed glaze base, probably
in increments of 0.2 % up to 1.6 %. In larger amounts Nickel oxide is
a notorious refractory material. It also has a reputation for being
"Fickle" I have had green, yellow and violet on the same pot, or green
and dark brown where there were variations in thickness.
Best regards,
