    Some time ago, there was a discussion the forum what is the best
    pickle. At a time I suggested that the only right way to do it is to
    boil jewelry in the 10% acid solution. This was not received very
    well, but the reason for the practice is to avoid the situation that
    you describe. If joint is really soldered, you can leave it in the
    pickle for a thousands of years without any harm. However, it could
    happen that joint is only appear to be soldered and only held
    together by flux. If flux penetrated deeply, the conventional 
pickling
    would not do any good, but joint invariably comes apart either during
    setting, or even worse during polishing.
