Steve I asked the folks promoting it at SNAG in Denver. They were
reluctant to disclose the full metallurgy, but admitted to a small
amount of calcium, so small that the total purity is still within
the US limits for 24K. I have a vague, unsure recollection of
another unusual metal as well, perhaps gallium - but probably
getting it mixed up with the no tarnish silver.
My guess is that they would patent this metal, so a search of the
patent archives should find the full art.
