I am a professional design polisher & split lapper of fine jewelry.
I have requests for Rhodium plating on most of the gold & platinum
work that I do for customers. I have very white Rhodium, but lately
I find that the whiteness is not consistant. I have been doing
nothing different. (I am using electocleaner, acid bath and all of
the rinses suggested).
I make sure that my Rhodium is:
a) covered, so no dust gets into it.
b) charcoal filter it on a regular basis
c) only add distilled water to it when needed
d) add more Rhodium when needed
Could the problem be that the pieces of jewelry that I do are not of
a consistant in size?
Should Rhodium be heated up at times or kept at room temperature? ( I
keep mine at room temperature, but sometimes I heat it up to give it
a boost, & then I change my bath)
How often should I be changing the bath? ( I have a quart bath size
and I use 2 Platinum anoids) I do large quantities of plating, and
change the bath regularly, but how often is suggested?
Any tips, suggestions, or help would be greatly appreciated.
