Featured a bit OT... explosion of pigments

is anyone around that could explain what exactly happens to the pigments when they heat them up to ~1200° C ? this here is a pen tray from Pierrefond.

 

I don't know the scientific explanation for what happens in the kiln or the glaze formula, but I do know it's called crystalline glaze.

 

Reading this explanation makes my eyes glaze over LOL. The link below may help you understand better if that's what you're looking for.
