Glass is cool

Watching this reminded me that during glaze formulation class when I was in college, the teacher mentioned that the ideal glaze would contract slightly faster than the clay as the whole pot cooled off, because that would make the pot stronger.
I could never wrap my head around the idea then, but watching this video made it completely clear. Thanks, youtubes!
