Cold Rhodium Concentrates

Gesswein

Made in Germany, these cold rhodium concentrates are designed to be easy to use and require no heat. The concentrates are offered in white and black. The black solution deposits a dark anthracite-gray rhodium coating up to 0.5 micron, while the white concentrate deposits a brilliant white rhodium coating that is hard and abrasion resistant. The white concentrate is available in 1 and 2 gram quantities, and the black solution is available in only the 2 gram size. Both concentrates should be mixed with 900 ml of distilled water, creating a 1 liter bath that is ready to use at room temperature.
