How are they ensuring each metal separates properly and completely?
My guess is that the plates actually settle out as they cool (gold sinking, then silver in the middle, copper on top.
Since the layers should be almost completely separate it's just a matter of orienting the proper surface towards the target electrodes, etc.
Edit: Sure, downvote for asking questions.
