Q. We operate a copper cyanide plating bath here.
It consists of Copper Cyanide, Rochelle Salts ⇦ on eBay or Amazon [affil link] , "free Sodium Cyanide", and Sodium carbonate.
It doesn't appear to be made up to any particular specification.
Can anyone recommend a typical bath makeup, giving a range of component concentrations?
Does this conform to any particular spec?
The copper plate is used as a mask for heat treatment of steel parts.
Thanks,

A. Rather than researching some 'best' theoretical ratios at this point, I would just start with whichever printed formulation from the Electroplating Engineering Handbook ⇦ this on eBay, AbeBooks, or Amazon [affil link] or the Metal Finishing Guidebook ⇨
your current analysis is closest to, Mike. That should get you to an accepted, workable, solution quickest, easiest, & cheapest.
