I think any material that is sold needs to be identified as to what
it is, and not mis-represented in any way.
That being said, I think traditional sterling should never be
confused with more advanced sterling alloys, like Sterlium Plus, that
is for sure.
Can I assume that those of you who are expressing fears about the
performance of Sterlium Plus or any of the other non-copper alloys
have actually worked with them?? Have you personally found the
Sterlium Plus or S57NA or S88 sterling alloys to perform worse than
traditional sterling? Does Sterlium Plus not oxidize as well as
copper alloyed sterling? My experience with years of work with both
the S88 and S57NA alloy sterlings have shown them to work easier than
traditional sterling, with far less fire scale issues, take deep dark
oxidation when required, and are quite easy to draw or roll. I don’t
recommend copper alloyed sterling to my students anymore because of
the many problems inherent in the metal. In short, the new sterling
alloys we now use make a superior product in my experience.
I have just ordered 2 ounces of Sterlium Plus casting grain, which I
will experiment with when it arrives. I want to see for myself how it
compares with other sterlings. How would one know, otherwise?
