Here's how we handled Rhodium.
Many folks buy it in a bottle, then pour it into a beaker, use it,
then pour it back into a bottle, maybe thru a funnel.
We found this procedure to trap and collect dirt and contaminate the
What I'm going to explain, we started with a fresh bottle because of
it not plating well. But your decision. You can buy rhodium
replensisher that will refresh it.
1. We bought a glass jar that you keep sugar or flour in, wide open
mouth. The kind with a rubber seal and pull down metal strap. Maybe
4" tall. Washed it first.
2. When we bought the rhodium we emptied it into the glass jar. It
was stored here and we dropped the rings into this jar to plate them.
So we never poured back and forth.
3. We had a rhodium anode and the hook on the other end was made
from a piece of platinum wire.
4. Although we didn't do this a lot, other jewelers have told me
they use an "Electro Cleaner" after the ring is polished and cleaned
to clean the item before plating it. You reverse the + and - to
reverse and the ring extracts away from itself any dirty surface
5. We put the bottle of rhodium into the ultrasonic to gently warm
6. After polishing/cleaning/steaming/electro cleaning the ring
BEFORE you rhodium plate it, imperative to not touch it with your
finger before immersing it into the rhodium.
7. Think like a surgeon on handling the jewelry (cleanliness) and
with new you should do great.
By the way there are strengths of rhodium. a 1 gram bottle has a
gram of rhodium in it and a 2 gram bottle has twice as much and of
course cost twice as much. Many jewelers use a 1 gram bottle on
plating repaired jewelry and a 2 gram bottle on items purchased from
