You're probably thinking of a "rollover lip" which can be found on the rear side of some oriented meteorites. This feature is caused by molten fusion crust droplets being deposited around the trailing edge of the meteorite and building up a lip around that edge. It is NOT the fusion crust peeling back and laying over itself.

Thank you for seconding that, especially since I don't have the source handy. I am interested to hear that you know of outer layers of slag folding in that way, as well. I certainly didn't know this was very common. I was contacted by someone who described themselves as an expert on slag of sorts last night, and hadn't yet received an answer as to whether that was a common feature of slag. 'So does the air flow fast enough around slag to create a similar effect as is sometimes, although rarely, seen with meteorites?' I wonder. Or 'is it not caused by fast flowing air, as well as heat, in the instances of this common occurrence on slag?' I, again, wonder. I guess that's beside the point, and I'll have to take your word for it being a common occurrence in slag.
