I have had better luck with transparent enamels on 970 Argentium
than I did on traditional Argentium. But not good on every color I
tried. Also, I had to melt and pour the 970 ingot, then roll out the
sheet and wire, because I couldn’t find milled 970. All-in-all,
mediocre results and too much work. Ran out of time experimenting and
have gone back to fine silver.
p.s. Need to add that I torch enamel, so your mileage may vary.
