What I want to do is create a brass ball at the end of a brass
rod. Can I do that by melting the end of the rod like as with
silver, so that it balls up on the end? I've never worked with
brass so I don't know what heat does to it.
You can ball brass wire, but you need a hot torch (fuel/air, or
fuel/oxy), and you need to be fairly aggressive with it. Hot, sharp
pointed flame, and pull it as soon as the ball forms, or the zinc in
the alloy will cook out and leave you with a pitted, lumpy mess. Even
with practice, depending on the brass alloy, you will still get a
fair number of rejects.
