Simplified graphic showing long-shore transport of sands from the mouth of the Nile up along the Levantine coast (today Israel). Glass factories at Jalame and Apollonia used the sands in glass production during Roman and Byzantine times. Along the way North, some of the zircon minerals contained in the sands drop out leading to the different hafnium isotopic compositions of Egyptian and Levantine glass. Also shown is the location of Jerash, Jordan.

I saw the Pompeii exhibit at the Reagan library a few years ago. I was absolutely astounded by the quality of glassware they found. And that was 79 AD. There was one glass that looked exactly like a modern day sundae glass.

I’m pretty certain we would all be shocked if we could see all the ancient books ,tools, and everyday things.
Nothing like a few million barbarian looters to ruin a civilization.

Hafnium was one of the last natural elements discovered. It is very similar to Zirconium. Hafnium has so many electrons that the innermost move at near light speed around the nucleus. This shrinks those orbits so the atom is nearly the same size as its chemical cousin Zirconium.

Wonder if this was because of middle men adulterating
the supply as it traveled up the coast?

I don't know about you, but hafnium is pretty much my favorite part of the glass.
