Ruthenium bath / ruthenium electrolyte for dark precious metal coating
The ruthenium bath is another platinum metal, which in contrast to the other baths, deposits dark to gray-black layers. This electrolyte is gloss-preserving and inspires with an extremely decorative color, which is also very consistent. It is often compared to black rhodium because their colors are quite close. Which of these looks more beautiful or better is, as with white rhodium and platinum, up to the viewer.
