Thanks for replies.
I forgot to mention I need to make alloy my self since I could not
find ANYsupplier in my country. I can buy pure platinum and other
metals but no one is having alloys. But I preffer it this way. I
like to make my own alloysso I can change composition slightly to
fit my needs. I do it in gold so platinum will not be a problem.
Iridium is really pricey here - TWICE AS MUCH PER GRAM OF PLATINUM!
Its crazy. But since we are using 950 or 900 those additions are not
big so alloy cost will rise only a little.
Ruthenium is quite cheap on the other hand. But I am little affraid
about its safety. I know it has been used many many years and its
completely safe in everyday conditions. But from what I have read
Ruthenium releases Ruthenium Tetraoxide fumes when its heated above
800*C - and these fumes are really toxic. Does anoyone heard about
this? I couldnt find much about it - some international
suppliers mention about it, others dont. So I dont know what to
I am thorn apart between 950PtRu, 950 PtCu, 900/950 PtIr.
Since it will be my first time making my own Platinum alloy I think
I will make one(probably Pt-Ir or Ru) and next time I will make it
different for trying. This way I will find which one will fit my
work preferences best. Ofcourse I have beed working with platinum
jewelry before but it was when I was working in UK - and we used
ready made stock for fabrication. But unfortunetly no one knew WHAT
ALLOY IS IT! Its rediculous for me
Yes yes, I know I need all that equipment for Platinum,
contamination, safety etc.
I also understand there is no EPIC ALLOY that will be easy to work
and whenpiece is finished it will withstand everything and will be
forever in perfect condition. But I would like to pick one that will
be close to that I mean, I always want to make things better then
the others. Many jerellersin my area doesnt give a shit about alloy
compositions - they just mix andmelt scrap Other use poor colored
white gold etc etc.
