What will this finished silver be used for? Melting scrap is one thing, making it useable is another task. When heated to the melting point on a solder pad, silver and gold will tend to form a ball. Just as you said, ball right up. If you're trying to recycle then a solder pad will not do. You'll want a hand held crucible, ingot mold, and probably a rolling mill. A good atmospheric torch save lots of headaches. Borax when used in this manner is used dry. Toss in a couple of teaspoons full as the metal melts. Might even need a second dose of Borax.
I would imagine the black you mentioned is caused by the torch.
