Sorry Henning but this is a U.K. forum and I’m not sure if anyone will be able to translate your post

Argentium is the registered trade name for a particular low tarnish alloy. In the UK it is hallmarked as silver925.
Once altered as you describe it is no longer Argentium, but can still be hallmarked as 925. Dennis.

So Argentium is hallmarked 925 not 935 in the UK?

Yes, yes, yes. I had to add the other 2 yeses as one yes was too short for the forum ;-)

Argentium 935 is marked 925 (sterling). The 960 version, which isn't as readily available, can have the Britannia (958) mark applied. I'm not sure if anywhere is now stamping the 935 mark - though it was used in Europe and Scandinavia before the 1970s.

Australia still stamps 935, although we don't have "hallmarking companies" it is completed by the Jeweller

I’ve never known the 935 mark and have been having my work assayed since 1979

Caroline, 935 only applies to Argentium

Yes I understand that but as we tick a box of recognised metals I was just saying I’d never been aware of Argentine even now. My answer was more in relation to the last line of George’s post about 935 being used in Europe etc in the 70s

The 935 standard is nothing to do with Argentium (which is a relatively recent development), but was an alloy popular for watch cases, especially in Switzerland and Germany, I believe, and was also used in Scandinavia - you can still get it there and is considered the best silver for viking weave.

As I understand it The 935 mark ceased to realistically exist for the majorities of hallmarking countries after the introduction of the 1972 (enacted in 1975) international convention on hallmarks.

We've managed to go rather off topic, however, and I think the answer to the original question is that the resulting alloy may well be 960 parts silver, but will not necessarily be Argentium 960, which requires a defined amount of Germanium, inter alia, that may not be present if 999 has simply been added to fulfil a mathematical formula.
