Acid based solution used with platinized titanium anode. It produces a shiny white color. Ready to use, they come with one pint bottles containing 1 or 2 grams of Rhodium. It will plate directly on gold, platinum, or nickel. For silver or copper alloys, it is necessary to pre-plate with nickel first, followed by rhodium.

Many jewellers have discovered that the 2 gram/pint formulation gives a significantly better finish then the standard 1 gram solution. The rhodium content of this bottle is double (2 gram) the standard formula. The solution contains half the volume of liquid additives which makes it more concentrated.
