Pickling and Annealing Nickel Silver

Hi Orchid friends,

I currently have a student working in nickel silver. Does anyone
know what color to look for when annealing nickel-I don’t use it
much. Also, does the nickel pickle get the metal truly clean? Does it
work as quickly as regular pickle (like sparex with copper for
example)? And finally, would you just neutralize it with baking soda
the same way as regular pickle?

Thanks in advance for any advice on this.

My Best,
