Hi,

I have the following queries:

    1. I plated an item which had lot of recessed areas and the plating
    did not happen initially in recessed areas until I increased the
    voltage further. But that obviously resulted in uneven thickness of
    the plating. I know its because of uneven current density but is
    there any way to enure uniform thickness throughout the piece, even
    when the piece has lot of recessed areas. 

    2. The rhodium solution gets trapped in the recessed areas and even
    sudden jerks/ shaking the pieces does not remove it. Thus there is
    lot out drag out of the expensive solution. Of course the drag out
    di-ionized water can be re-used but i prefer getting the solution
    back into the rhodium bath. can anyone suggest a solution. 

    3. How do I remove rhodium from a piece of jewelry to get back the
    gold base. Is there anyway I can electrostrip rhodium. If not, whats
    the solution to this problem. I have customers who change their minds
    after getting their pieces rhodium plated and want the gold base
    back. 

    4. Why does a gold plating done over rhodium plated object have very
    less longivity. 

    5. Whats the safe/ best way to polish chains. 

Thanks
Rahul
