How did you deal with the molten silver dissolving oxygen from the atmosphere? Even if you keep it under a reducing flame, you'll have to take the flame off eventually and some O2 will get in, which will cause defects as the metal solidifies.
Yes this definitely happens to an extent. I mostly solved it by grinding away the outside. I used 2x the amount of silver that I ultimately needed, knowing I’d have to remove some.
I’m figuring it out as I go, but it doesn’t seem to be a major issue.
