The way I heard it, the material gives off spectral lines by virtue of the
heat it endures. You can certainly ionize anything by heating it hot
enough. The heat source is an electric arc, of course.

Precisely.

Correct, so it's filtered.

Few particles formed by EDM will be that small.

Thank you.
