I was under the impression that most cast pieces in platinum are
alloyed using cobalt. Thought it improved the castibility (if
that’s a word) of the platinum. Maybe our resident PGI technical
ed. manager can give us some info, if he’s lurking…Jurgen???are
you there?
Sharon The platinum part of this piece wasn’t cast, it was
fabricated. 18k gold was cast around the 10% iridium platinum.
Okay Rick- I’ll bite. Tell us about the didymium glasses! Where
do they come from and how much,etc. TIA-RL
The didymium glasses are what glassblowers and beadmakers use to
protect their eyes and cut the yellow sodium line. They are
expensive $140 is what I paid for my pair, but now I can wear my
optivisor over them and see what I am doing. I had made an
optivisor with a flat plastic welding filter- its history! Well
worth the money- I got a #6 tint (I think)- if you do even
occasional platinum work.
I may be mistaken, but these are the same kind of glasses used
by those who make glass beads or blow glass. They usually run
around $60.00 (or higher) They can be found on the internet if
you look in the stained glass sections.
