I’m trying to get a handle on the various methods of what to plate over what and why.
Gold over silver directly seems to be acceptable for some, and absolutely forbidden by others. Gold over copper, the same. Silver over copper, the same.
There’s often talk of using nickel as a barrier plate underneath a variety of different platings.
My question is this: are there alternatives? With at least 10% of the population being allergic to nickel, it seems like a risky proposition to use it as an underplate on anything that might have skin contact. So are there options for a barrier solution that’s not problematic?
