Hi Erik,

unfortunatly most of these balls are also anthropogenic pollution.
Especially industries like coal-burning power plants, foundries and metal
processing produces such spherical particles.

That's why one has either to go in the stratosphere to collect
micrometeorites or to use unpolluted sources like Antarctic wells or ice
or sediments - from the times where there wasn't human pollution,
to be able to isolate them.

Especially in the late 70ies and early 80ies it was quite a fashion among
the collectors to try to find micrometeorites by filtering rainwater.

Best!
Martin & Stefan

Eric, try this:
?One way to collect micrometeorites is to set a large shallow tray of
water outside for a couple days. You should see some residue on the
bottom in time. Cover a magnet with Saran wrap, wax paper or some other
type of material. Pick up magnetic material in tray with your magnet
and set on paper to dry. Observe material with a good- strong
microscope. Some of what you see will be spherical balls- those are the
micrometeorites.

Steve from the nuggetshooter
forum(http://www.nuggetshooter.ipbhost.com/index.php?showforum=4) posted
that 2 years ago.? There were great links and photos but the sites are long
gone.? I quote, "If you're not having any luck hunting macrometeorites, try
hunting micrometeorites. You'll never get skunked."

Can someone with a microscope try this and post pictures if they can?
