    Well Dave, In fact the understanding of how it happens has everything
    to do with how to do it in this case.  Scientific speculation today
    may be scientific fact tomorrow. In reality, we use many kinds
    chemicals and varying techniques in the polishing of stones and those
    facts can tell us a great deal about how to properly use them to
    effect the results we want. Few of us have taken the time to create
    charts, graphs, or to make notes on specifically what powder,
    carrying medium, lap speed and pressure works best on which stones. 
    Most of us work by gut feel in this respect, especially if we limit
    ourselves to only one kind of stone.  The work done by researchers
    can give us important perspective, valuable data and documented
    details about how to employ materials and techniques to achieve our
    results more quickly on more diverse material and to a higher degree
    of perfection. 

    How to properly polish gemstones results from how gemstones polish
    just like how to solder gold, silver or platinum results from studies
    on how solder functions or how alloys alloy. 

    Sorry if it means nothing to you but, I teach gem cutting and I
    believe my students deserve to now the mechanics of what happens when
    they do something so they can be better cutters. 

    PS;  All, I have found the articles I was looking for and will
    provide a better explanation than I gave previously just as soon as I
    can digest it all again. 

    Cheers from Don at The Charles Belle Studio in SOFL where simple
    elegance is fine jewelry! dcdietz AT attbi.com
