    Greetings All, I haven't caught all the threads for this subject but
    what I have read seems very informative. It's pretty ironic that I
    was reading this months issue of Lapidary Journal and came across an
    article that covers this subject as well. The name of the article is
    'The Metallurgical Balancing Act' by Sharon Elaine Thompson. The
    article is quite enlightening probably because I am still learning.
    The article covers information about the alloys and some of the
    reasons certain ingredients are used and why the ratios are important.
    The dangers of recasting/re melting used gold or silver is also
    covered, but with a twist that I didn't know. Not only do you have
    problems due to depleted zinc and possible solder contamination but
    it seems that metals alloyed from different vendors can also give way
    to problems. If you get a chance read the article, it is very
    interesting, at least for me it was. By the way I do not work for
    Lapidary Journal nor do I have the pleasure of knowing Sharon Elaine
    Thompson. 

I'll be listening
