Oke...
I am ashamed, very ashamed (I should've known this, well I knew it, just forgot it) But the Old german silver what Dale was talking about was most likely not actual silver..
it is something close to what we call Alpaca nowadays (except that it also had a percentage iron in there). Which, in case this assumption is correct does explain the the reasons why sterling silver ligatures are more resistant and slighlty dull (according to the chart in my previous post).
This would clarify a lot of the questions I had about that..
Next question (to myself) how to add this percentage iron in modern alpaca alloys.. Hmmm.

PS:
The genuine German silver, made from the original ore of Hildburghausen in Henneberg, analyzed by Keferstein, was found to consist of copper 40.4 per cent., nickel 31.6, zinc 25.4, iron 2.6.

But I am straying way to far of the original topic of this thread. My apologies.
