Julie:

    This has come up several times on orchid. 

    I called Handy and Harmond refiner co. and asked to talk to their
    cheif Metelurgist. 

    They connected me with min and this is what ne said. He said first I
    will have fo look it up and that Is I would hole for a few minutes he
    would find out. 

    Well he told me this: 

    1st. you have to have a temperature on the oves that is accurate
    within 2 to 5 degrees . 

    2nd If your oven temp is that good this is what to do. 

    3rd.put the Sterling Silver part in the oven cold andturn it on and
    bring the temp up to 1,000 F and hold for 3 to 5 minutes, then shut
    the oven off and let ciil down to room temp. and the part will be
    tempered. I did what he said and my Sterling Silver 7x7 Yellow Stone
    Elk came out tempered,which I was really happy. 

    I had been having trouble with the elk and my Caribou game heads
    come out too soft and gave me a lot ot trouble when people wore them.
    Mow for Gold On 14 K gold he said to run the temp. up to 1200F  and
    repeat the procedure that was used for Sterlink. It worked Great. 

    Since that I have been buying 14K gold called Spring gold and it has
    even been better for the Elk an Caribou. Hope this helps solve your
    problem.
