    Hi, Deb, With silver, there are no particles, so you can always etch
    it facing up. But with the magnetic stirrer, you can do both sides
    easily--and evenly. With copper and brass, I'm not sure, but I think
    it likely that the sludge would be swept away by the "current" on
    top. But, truthfully, at the moment I can't be sure I've actually
    done that. Most of my etching is in silver. If you like, I'll try it
    and get back to you.
