Toroid cores for GDTs

["Tesla list" <tesla@xxxxxxxxxx>]

List,

I acquired some nondescript and unpainted toroid cores, which I would
like to use as gate drive transformers for a SSTC project.

Unfortunately I do not know neither the manufacturer nor the mix nor
the material. The only value I could figure out is the AL factor.

Are there methodes to find out if the cores were made of powdered
iron or of ferrite? And of course I would like to know the frequency
range of the cores as well.

Any help is appreciated very much.
