[Jewelry making - Article 00753] - [Orchid] Platinum assay

    How is Platinum assayed? We have been offered Pt direct from a miner
    and wondered how it will be assayed by refiners. Has anybody got
    some experience as to how this is done properly, what is paid
    upfront to the miner ( we are only passing it on ) and how the Pt
    will ultimately be refined (meltloss etc.) and the costs thereof?
