Oxidation of heated nickel plated parts

I had some Ni plated ceramic oxidize after 920 sinter today... Could something in our Ni bath be causing this oxidation? Thanks

Yes. If parts are going to be heated like that, the nickel bath must be free of organic brighteners. Do you use a Watts bath or a Sulphamate bath, Jason?

We use a Sulphamate bath....
