Hi Todd,

    I regret that you feel that a number of us are guilty of criticism
    that may bring this forum into decline. 

    The fact is I've refrained from posting to correct bad advice many
    times for fear that somebody would be offended and start an argument
    on the forum. In these cases I've made contact off forum to
    straighten out goofy beliefs. 

    This matter of quench is a far more serious matter. You are handing
    out very bad advice with your "plunging so fast that no vapor or
    particles escape into the air." 

    I am not surprised you know someone who followed bad practice for
    years and did not get Silicosis. Remember, thousands of people smoke
    all their lives without getting cancer. The same thing happens with
    inhaling microscopic silica. Not everybody gets sick! 

    I know the story of the two fellows who founded Prevest in 1954.
    They made great investment powders for many years. One founder was
    dead with Silicosis by 1987 and the other passed two years ago in his
    90's of old age with no signs of Silicosis. Neither fellow wore
    breathing protection in quench, or any other area.

    No Todd, quench is far more dangerous.

    No, we are in the field of developing and making technical materials
    for jewelers, and as such know far more about these materials than
    jewelers do, for the most part. We know little about the actual
    creation of jewelry and we do not make that claim. 

    I didn't read any other post, nor did I write anything that would
    indicate I am an expert on Jewelry making. I did, however, attempt to
    make many people benefit of good advice by correcting the very
    dangerous advice you had passed on. 

    I don't have a clue how to create a beautiful piece of jewelry---it
    is not my field of expertise, it is yours. I am a materials guy and
    feel a responsibility to the industry I serve to help put a stop to
    silly home-grown ideas drawn from "I guess technology" instead of
    from actual engineering study. 

    Todd, you are dead wrong about this and I am sorry if you must take
    this as a personal attack. It is not. It is an effort to stop any
    thought that there is any safety in quench--aside from breathing
    protection. 

Regards,

Bill
