Argentium 970 is currently sold in grain and only from this one dealer, G&S Metals. I just spoke with them and asked why they do not offer it in sheet and other forms. The answer was they have not had the request for offering it. I explained the interest of enamelist. And was told they have a blog on the home page top left. They would be happy to listen.So enamelist here is an opportunity. www.gsgold.com/ blog away!
I will purchase the grain and start some testing for plique a jour. I do not see a need for cloisonne as fine silver is great. But it would also be a good metal for vessels.
