[Jewelry making - Article 00009] - [Orchid] Annealing Silver

All,

    I was wondering what kind of environment people on this list might
    suggest in which to anneal a silver coated specimen.  I have read
    through several archived posts on HOW people have annealed silver,
    but I never came across what the composition of the environment
    (air, nitrogen, oxygen, etc) was in which people annealed their
    silver.  I ask this because I have performed an anneal at 600oC for
    about 3 minutes in a nitrogen environment, and when I allowed my
    specimen to cool, the pure silver was cloudy and not at all lustrous
    as it was before the anneal.  It was very disappointing, and I am
    trying to figure out the reason behind the cloudiness.  Any help or
    input would be greatly appreciated.  If it helps at all, the silver
    was 100nm thick over a layer of titanium that was 20nm thick. 

Thanks in advance,
brian
