Wikipedia states that ancient Peruvian metalsmiths applied gold with electroplating, citing a 1979 article in The Journal of The Minerals, Metals & Materials Society. I'm not familiar enough with this journal or academia to assess whether the claim is solid, or if later research confirmed or refuted it, but I am skeptical; what would be the source of charge? Why would such a valuable technique be abandoned?
