    Hi Everyone, I have a perplexing problem and hoped that one of you
    brilliant jewelers had a suggestion. 

    I was sponsered by a metal supplier to make a woven bracelet (that I
    have done in 24K already) in platinum.  I have woven Pt 900, which
    to my understanding is Irridium.  I use it extra  soft and
    occasionally have to torch anneal it to soften it more.  No Prob.
    The supplier suggested (to qualify for the pureness expected by some
    countries) that I use Pt 950 instead.  The alloy is Ruthinium I
    believe.  So when I got the 52ft of 28gauge metal to weave it was
    too springy, even at a extra soft anneal.  I called and they said I
    could kiln anneal it myself. I was told 1650 f minimum, 1800 f max
    for 15-20 minutes then slow cool.  OK, thats exactly what I did and
    now my PT-RU is soft enough but  is quite black.  I am pretty sick
    about it and wonder what to do next.  

thanks for any suggestions,
t lee
