Casting Platinum Silver Alloy

#1

Hello Orchidians,

I have been reading about the platinum silver and want to have
something cast in it. The piece is to be paved with diamonds and
engraved. As there are three different alloys offered I am wondering
if anyone has advice about which alloy would serve this function
best.

Thanks,
Janet

I have worked with it a little. All are plenty soft to set or
engrave. We rolled 4.5mm all the way down to .20 mm with no
annealing. We could go thinner but the point was made. You should
contact Chuck at American Bullion to talk to the most knowledgeable
man on the stuff. I like the 3.5% Pt for the color.

Is there anyone out there in a position to compare/contrast platinum
silver with argentium silver?

I’ve just started working for Art Jewelry magazine, and I’m trying
to interest the editor in a piece about argentium silver. She is
more interested in platinum silver. While I’d love to thoroughly try
out both, I’m not sure how realistic that is.

Any way, if someone has tried both, I’d love to get in touch with
you. If I can get an article approved, I’d be interested in
interviewing people who have tried out either type of silver, with
good or bad results. Volunteers?

Noel,

  Is there anyone out there in a position to compare/contrast
platinum silver with argentium silver?

I am Stephen Wyrick in San Antonio, Texas I have been working on a
Very Special Chalice constructed of Alloyed Silver and 22 Kt. Green
Gold. As to the Silver: 95% Pure Silver, 1% Platinum,2% Ruthenium,
2% Palladium. I use a Hydrogen Gas for the melts. This gives a very
nice ritch colour and keeps the tarnish down.

Just a note about the metals.
