Hi,
On Fountain Pen Network I started a post about how pen nibs are made. A lot of the better pens have an iridium tip on a gold or steel nib. How does one get a small amount of iriduim (platinum group) on a thin piece of sheet metal?
My Complete Metalsmith by Tim McCreight lists "plating on the tips of fountain pens for durablility (especially osmium) as a use for the Platinum Group.
I think this is a better group to ask then the jewelry making newsgroup.
