I don't believe it is a trade secret that needs guarded. Ron
It is not secret and never was secret. If you read some old threads where I was writing about manufacture process you will see that at the begining I used vintage silverware as silver source. Later I quit doing that because of very different metal properties with same silver content. Now I use only .999 silver and make alloy myself with adding to crucible .074 copper, sure on special request I make different alloys.
