 Thank You sterling!!..That may be just what they are!..Zephyrhills is due
west of Cape Canaveral..Been there..used to watch the liftoff's from our
house..and the highest hill in town!..And indeed if that's what they
are?..they would be a cool souvenir!
Will this reply go to the list?..Kevin w.Decker.

Hi, Kevin,

    Now that you tell me that they are composed of
aluminum particles and since I looked up Zephyrhills
on a map, I suggest that they are from the solid rocket
boosters for the Shuttle.

    From NASA's web site:
The propellant mixture in each SRB motor consists of an ammonium perchlorate
(oxidizer, 69.6 percent by weight), aluminum (fuel, 16 percent), iron oxide
(a catalyst, 0.4 percent), a polymer (a binder that holds the mixture
together, 12.04 percent), and an epoxy curing agent (1.96 percent). The
propellant is an 11-point star- shaped perforation in the forward motor
segment and a double- truncated- cone perforation in each of the aft
segments and aft closure. This configuration provides high thrust at
ignition and then reduces the thrust by approximately a third 50 seconds
after lift-off to prevent overstressing the vehicle during maximum dynamic
pressure.

    And of course they would be melted and have traveled
at a high speed and all the rest of it. If that's what they are,
they make a pretty neat souvenir, even if they aren't tektites!
