PLATING PROCESS
Clean and prepare the piece or pieces to be pen rhodium
plated. With rhodium plating it is very very important that
all pieces are cleaned very carefully prior to plating. If the
pieces are not cleaned properly, the rhodium will
not stick to the pieces and contamination is
possible.
Note: Cohler pen rhodium should be used as is.
No mixing or adding water!
Note: Please clean piece prior to plating using cleaning
and prep instructions in prior section of manual.
1. Pour a small amount of rhodium pen solution into a 30
ml beaker or into the cap of the bottle.
2. Use at room temperature.
3. Attach the clean piece of jewelry to the (-) lead. Plug the
pen into the positive outlet on the rectifier. If using a
disposable pen, follow instruction for pen plating with
disposable plater.
4. Dip the felt tip of the pen into the rhodium pen solution
and let it sit for 1-2 minutes.
5. Turn on the rectifier and set to 4-6 volts.
6. Making contact with the felt tip of the pen and the piece tobe plated, slowly move the felt tip back and forth on the
piece. The felt tip should be moist but not dripping. The
pen tip may have to be dipped into the rhodium pen
solution several times before achieving a nice even bright
white electroplate. Look for tiny gas bubbles. This is a good
indication that you are pen plating properly and that the
rhodium is adhering to the piece.
7. When the results are satisfactory, rinse off the piece and
any excess rhodium under very hot tap water.
8. Pour rhodium solution back into the container to prevent
contamination.
