hi all!

    i have been attempting to raise a fine silver skin on a sterling
    piece of mine that i would like to have that sort of pearly white
    finish of matte fine silver. the studio i where i work i am noticing,
    has a great deal of rust in the water. this hadn't seemed like a major
    concern, until i was working on this piece and noticed after pickling
    and rinsing in said water the rust precipitating onto the piece as it
    dried. i had had a fairly good fine silver surface it seemed, but now
    when i heat the piece it turns a funky grey again and i'm seeing
    ghosts where i had noticed the rust. we have mixed up a new pickle
    with distilled water, any suggestions for getting rid of this? my
    studio mate suggested oxidizing it again and quenching it in a pickle
    containing both sulfuric acid and hydrogen peroxide, but seeing as
    i'm home now i thought i'd ask here too... will polishing the piece
    again likely do any good or does someone have a suggestion for how to
    remove it chemically? 

    thanks! and check out my studio mate's website at larissadahroug.com!
