Someone discovered that the properties were very similar to Copper Sulfide. The problem is that to make it you must mix two powders and heat them, but the heated mixed powers also produce Copper Sulfide as a contamination. In this case the contamination has very interesting properties that make it look similar to a superconductor, but it's not a superconductor. And that probably caused the mistake.

I would imagine they didn't get as far as LK-100 ;)
OTOH, WD40 is still selling pretty well . . .
