That thread is all over the place, the only two vase-related things I found were:
a) A woman in Russia hand-made a vase that looks similar to the Egyptian ones.
b) Some guy said the vases are forged, and made in modern times, because their provenance is not proven.
Neither of these strike me as particular interesting statements, and the rest of that thread is about completely unrelated topics. I closed it at the "Dudes Think They Can Prove Atlantis by Measuring a Vase" link, because that's exactly the kind of condescending crap I'm talking about.
Here's a nice compilation of evidence showing it's completely explainable how they could have made them.
