Why this rock is probably not a meteorite:
1) No fusion crust.
2) The dark stuff on the large piece is glass, and glass occurs in
the smaller pieces, too. Meteorites don't have massive glassy parts
attached to crystalline rock. Fusion crusts are glassy, but they are
very thin and are located only on the surface.

What is it?
It was found in rural Missouri. Like number 26,
it's probably a debris from an old smelter or forge. If sand and limestone
are heated to high temperature, glass will form. The piece on the
left looks like glass poured onto rock.
