Grain size can be from sand to  - 400 sieve....working temperature is 1100 degrees C

Do you have any black sand?

Much apprecieated

Its a little technical.... but basically tuneded frequency heat source heats the suspeptor material and that smelts the precious metal. Do you have a pail of magnetite?

Are you referring to a microwave oven and kiln/furnace? A microwave is a tuned
frequency heat source but for smelting, some magnetite or flux material is needed
to excite the material and get the smelting going. The flux works quite well.

Recovering precious metals from black sands or magnetite, it is not simply smelting
the material and ending up with a bead of the precious metals.

Am not going hot enough to smelt the magnetite, only for use  as a susepter.
do you have a pail of black sand that I can puruchase from you?
