Abstract
In 1926 E. S. Hedges observed that the film which forms on a silver anode in a cyanide bath at high current density is periodically formed and dissolved. A study of this phenomenon has shown that under controlled conditions of temperature, stirring rate, and current density in a cyanide plating bath this recurrent film formation can be employed to brighten or polish silver. The process is particularly well adapted to use in the fabrication of small, irregularly shaped objects.Keywords
