Dear Mr."(Plenum)",

I received your email with images attached.

But just by looking, it is not possible to determine if they are or are not micrometeorites, because of industrial processes which produce similar microspheres. Such as is the case of coal-based electrical energy production, metal foundries, high-temperature ovens, etc.

(")

99.9% of the microspheres which come from the atmosphere are from industrial origin. The way to collect them is from rainwater in basins, as wide as possible, and preferably after periods of drought and/or after important meteor showers such as the Perseid, Leonid, or Gemenid. The collected water is filtered through filter paper and the metallic pieces are then separated (from the paper) with a magnet. Then the material obtained can be observed through a microscope and analyzed later.

I hope to have been of some help � ��"
