Pen Plater Superblack Black Rhodium Solution

Pen plating puts a plated finish exactly where you want it at the bench, for localized, selective work. Cohler Superblack Pen Black Rhodium Solution produces a deeper, darker grey-black rhodium plate on gold and other precious metals than standard black pen rhodium. Formulated specifically for pen plating, it uses a different pH and a higher concentration than bath rhodium solutions to deliver crisp two-tone accents, touch-up repairs, and uniform dark finishes. Supplied as a 1 oz concentrate carrying 1/4 gram of rhodium. For professional use only.

Features

• Deeper dark finish: Rich grey-black tone for bold contrast and modern looks.
• Pen-plating optimized: Concentrated chemistry for fine control and localized application.
• Durable and tarnish-resistant: Suitable for high-wear accents and touch-ups.
• Great for two-tone work: Selective plating on rings, bezels, and textured elements.
• Versatile applications: Dark accents to complement black or deep-hued stones, selective two-tone effects, and restoration touch-ups on gold and other precious-metal substrates.

Compatibility

• Pen rhodium solutions differ from bath solutions in pH and concentration. Use with pen-plating equipment and appropriate tips.
• Not all metals can be rhodium plated. Verify process compatibility before use, as successful plating requires correct equipment, chemistries, and process steps.
