I am looking to apply a hard, thick gold plating that will wear well in this application. Which type of gold plating solution would be best for this project? Thanks. john_talcott. John Talcott band instrument.plated gold cyanide,Gold Plating Baths - EPNER TECHNOLOGY INC.Three types of gold plating baths are available for use today. The alkaline bath, at a pH of 9.0 to 13.0, provides good throwing power and reduces co-deposition of base metals. The neutral bath, pH 6.0 to 8.0, will permit alloy formation through base metal co-deposition and will cause little or no attack on delicate substrates.
