[Rockhounds] Fl. marbles

That suggestion isn't really all that helpful, Dave, because as is well known, most of?us long-time rockhounds have already lost all their marbles.? Maybe some of the newer ones will still have some, though.

Since we are on the topic of fluorescence, try some of your old
marbles, a lot will flouresce quite nicely due to the uranium salts
that were used to color them; some are still warm under a geiger
counter also.
