    I agree. As Cooksons insist on assaying scrap anyhow, I collect it all in a Nescafe jar regardless and take it in when I have a kilo. I find their scrap pots too bulky so if I were sending it in, I would probably use a heavy duty freezer bag inside a jiffy bag. Dennis.

    Alternatively, once you have silver chloride you can mix it with cream of tartar (IIRC!) and rub it onto copper to leave a very thin plating of silver on it.

    Thank you Peter.....your clarification on this kinda stuff is always helpful........but the cream of tartar sounds like dubious hard work!!
