On an artist's forum, I asked the same question, no one had cut silver
with a plasma cutter there either. However, somebody in the group got
curious, and tried it on scrap silver. He reported that it worked fine,
with a bit of dross. The group suggested cutting over water to save the
silver from the kerf.

I have not tried it myself as of yet.

I happened to be talking to a jeweler who was working on a large piece
of 10 ga (about 1/8 inch) silver. She needed to make multiple closed
end slots, each around 6 to 9 inches long. She tried to use a jeweler's
saw, but it was extremely slow. She showed the piece to me, and asked
me how I would cut it. I immediately said plasma cutter. She is
probably going to come over to my shop to cut these slots.

Has anyone here ever cut silver with a plasma cutter? Anything I should
know? I asked on an art list I hang out on, and no one had ever done
it, although everyone seemed to think that it could be done. My
understanding is that plasma cutters will cut any metal, although the
speed of cut varies somewhat with the metal.
