While recently in Mexico, there is a glut of metal sculpture, not a piece of
which I saw bought. Schools of fishes, large sailfish, small sailfish,
three dimensional trees all cut out of a flat piece of metal, then pushed
out to achieve depth. I can see the cuts, and they are definitely either
plasma or laser. Some of them are very thin. How is it possible to
differentiate between laser cut goods and plasma cut? Just how thin can a
plasma cut be?
