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.

I wonder if using the gas shroud from a mig/tig welder might work?

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.
