That's the age of the Dakota Formation right outside the door and yes, I could see ceramics possibly existing that long. The formation only has diagenesis (cementation) and a bit of brittle deformation from uplift.
To get metamorphism it needs to be deeply buried and squeezed in an orogenic province.
Your hypothetical outcrop will have to have buried by transgressive ocean sediments (sea level rise) then exposed again by regression. So a coastal location at a delta would work, or a coastal swampy area along a passive margin that is not going to experience much tectonic modification.
There are speculative maps of the continental positions 100 my in the future on the net. The positions are less speculative than the sea levels, in my opinion.
So yeah, go ahead with the ceramics. Glass is a different story, it may suffer "de-vitrification" in the long run.
Space/Science » in reply to Dinosaurs, as far as we know, didn't have mass production...
