    Porcelain burnishing media (2mm + 4mm balls from Rio Grande) works
    very well for burnishing, but only if you break-in the media by
    running it day and night for a week (mix in distilled water,
    burnishing compound and some scrap metal).  Until that time it acts
    as a mild abrasive and will produce a frosted effect.  Instead, use
    a fine cut plastic media (distilled water, deburring compound),
    followed by distilled water, burnishing compound and either
    stainless steel shot or porcelain media for a final finish.  I use
    porcelain media for a piece with a bezel so that the bezel strip is
    not as work hardened as it is with steel shot.  Hope this helps.
