I have been searching in vain for about Platinum PMC.
I know it exists, and is at least available in Japan. Does anyone
know if there is anyone who imports it to the US? Even if not, if I
am able to get some somehow from a contact in Japan, does anyone
know how I can find out on how to work with it? I have
someone who wants very badly to design her own wedding rings using
platinum clay, and I am trying to find out if this is possible.
I’ve not heard of it as a jewelry product, but the first thought
I’ve got on that regard would be that most jewelers would not have
funace capabilities capable of sintering a platinum pmc product.
Remember that if it’s a true pmc, you’ll have to be able to heat it
to somewhere near it’s melting point in order to sinter it, and this
is MUCH hotter than gold or silver PMC products, if the platinum
product is a reasonably high percentage of platinum…
the subsequent thoughts are that all PMC products tend to be
somewhat softer than the “cast” versions of the same metals. I’m not
sure you’re going to want to use a platinum pmc for a wedding band
that’s softer than dead soft annealed cast platinum alloys. Perhaps
they’ve alloyed it with something to improve this adequately, but I’d
And then there’s cost. With PMC products usually commanding a price
that’s a significant percentage higher than the plain metals they
contain, I’d guess a platinum PMC would end up being a very costly
way to make a platinum ring… PMC products are indeed fascinating
materials, and different in working method and result from
traditional metal working. But just intuitively, I’d guess a platinum
PMC would be a rather more difficult and costly material to work with
than the gold and silver products. Perhaps I’m wrong, but that’s my
first intuitive reaction…
Why not just do this the traditional way? Help your client design
her rings in wax, and have the results cast normally, in platinum.
There are soft waxes you could choose that would work rather like a
