NON-WIPE COPPER BLACKENING SYSTEM
I recently read a response by Ray Delorey),
letter 1198 regarding chemically blackening copper. Ray recommended a 1% -- room-temperature dip of "zinc purifier" that is used in a "cyanide zinc process" as a non-wipe system for this blackening process. I would appreciate help in locating a source(s) for this "zinc purifier".
