Brass base material plated with silver over copper

When I bake parts at 260 deg C it turned green. Can anyone tell me what is wrong?

Thanks,

The copper is migrating thru the silver. You need to use a nickel strike. I think that a sulfamate strike will work better on copper than a Woods strike. A Watts nickel with the pH lowered might work well also.
