Plating with black ruthenium leaves an even, smooth pure black coat on the plated object. Ruthenium is a rare and beautiful metal that deposits a sleek subtle shine. Black ruthenium's dark hue enhances any piece by contrasting the normal silvery golden finishes found on jewelry. If you haven't already, be sure to check out our blog post on how to set up your plating station to follow the process described below.
Let's set up the precious metal bath for plating! Pour 1 liter of TWL Black Ruthenium solution into a 1 liter glass beaker and drop the magnetic pellet for stirring inside. Put the beaker on the magnetic mixer hotplate and heat to 160°F, letting it mix on a medium-slow setting for 15 mins. Install a candy cane-esque platinized titanium bent anode so that the long end is in the beaker. Connect the positive lead of the rectifier to the anode and set the rectifier voltage to 2-3. (recommended 2.5 volts) and the plating time to 1-3 minutes. And just like that, you're ready to plate!
Now, if you're plating a brand new item you can skip to step 5, but if you're plating an older piece or performing a repair you should complete all 13 steps. Note: when we say to used distilled water it is because distilled water is containment free and will ensure spot free drying.
Pro tip: you can reuse your electroplating and acid activation solutions but you should replace them weekly. All distilled water rinses should be replaced daily.
