Hello Charles-

    According to Lange's Handbook of Chemistry, 12th Edition, page 4-107
    and Handbook of Chemistry and Physics, 82nd Edition, p. 4-83, silver
    permanganate (CAS Reg. No. 7783-98-4) is violet to dark violet
    monoclinic crystals, solubility in water of 0.9 grams per 100 grams
    of water and decomposing in 95 percent ethanol.  It doesn't look
    like it would be inert enough to be useful on jewelry.  Since you
    are a DDS, I know you have had sufficient chemistry to be aware of
    the explosive hazards of permanganates.  I blew up a burette right
    next to the Professor in a quantitative analytical lab one time.  I
    was trying to clean the thing with a conc. sulfuric acid/potassium
    permanganate solution when the classical sodium dichromate/ sulfuric
    acid mixture was not effective.  The thing went off with a heck of a
    loud bang and totally shattered the burette.  Fortunately, no one
    was hurt or sprayed with acid.  I was holding the burette down in a
    deep soapstone sink.
