Cna anyone tell me exactly what nickel activators do? I'm looking for a
nickel activator that is alkaline to use with cyanide gold in a brush plating
operation. Most nickel activators I've tested are acidic and that's a no no
around cyanide.

If anyone knows of a alkaline nickel activator or a good looking non cyanide
gold solution, I would much appreciate hearing about it. Cyanide makes me
 nervous. One potassium aurocyanide solution I sent away for has a p4hof 4.7.
How can a cyanide be suspended in an acid ????

Thanks

Terry Collins
