Why this rock is probably not a meteorite:

This is a strange object. It has a glassy exterior that has cracked like the glaze on an old dinner plate. It was found on an old farm site. We are unaware of any terrestrial rocks or meteorites that look like this. Meteorite fusion crusts don't crack like this.
What is it?

We don't know but we suspect that the glaze, at least, is man-made.
