[Jewelry making - Article 00000] - [Orchid] Overheating Yellow Gold

[Peter Schneider]

    This is off the subject, but Peter Rowe a while back gave
    temperatures, colors and times for annealing gold. He wrote that
    yellow gold should be heated only to dark brick and immediately
    quenched. Previously, following some threads in the archives I had
    found that one should either heat gold up to orange for 30 seconds
    or 30 minutes so had sort of split the difference, to my regret
    because cracks invariably formed on rolling out. My question is,
    once yellow gold has been overheated, is it possible to start again
    and make another ingot or does the gold have to be sent off to a
    refiner. It is only about half an ounce so.....
