I’ve never heard of an actual granite pan. You surely mean a metal pan coated with a combination of silicone-ish things and silica, and maybe the silica is derived from granite.

Sadly, it seems that some of these things still contain potentially nasty highly fluorinated compounds. Here’s a patent for such a thing:

Hmm, the “FAS” additive in the outermost layer has a perfluorinated C6 chain. Whoops. I wonder whether this is better or worse than PTFE. At least intact PTFE ought to be harmless. PFHxA is not so wonderful:

edit: some brands of “ceramic” nonstick pans are quite explicit about being PFAS-free, and CA AB1200 really ought to help here.
