Gold plating

Mostly gold auri cyanide KAu(CN)2 is used in gold plating bath. Why cannot gold auro cyanide KAu(CN)4 be used or recommended in Gold plating baths? One thought is that it may use less electricity, but as gold is more highly complexed in KAU(CN)4 it may produce a finer deposit.

Read the journal articles from the 1950's. Savings in electricity are moot in hard gold plating since the additives cause a dramatic drop in bath efficacy. Our cobalt bath operates at about 25%.
