Isn’t there rock similar to (?) which when heated is reduced to volcanic ash in the area? (plus an abundance of rapid regrowth of trees)
Can’t recall if I got that from Readers Digest, National Geo or Athelstan Spilhause (or why I recall).
Am prepared for a quick slap down however.
I would suppose an event could have caused an eruption.

Considering the various ages of the ash it was a recurring event? This was likely one of them.
Would firing the pots artificially age the crystals?
Hey, those stairs aren’t ADA compliant!

A day or two ago there was a thread on FR about the recent banning of Microbeads. This led me to reading about pumice. Pumice is formed by lava that had air bubbling up through it. It is filled with open cavities, I suppose like Swiss cheese, or a sponge. Anyway, it floats. Giant rafts of pumice are adrift, to this day, in our oceans. They have been a means of transportation for plants and animals from one continent to another. I suppose the Mayans may have run into pumice (lava) washing up on their beaches. Evidently, there was intercontinental swapping even before “man”.
