    I could be wrong, but I don’t think this has so much to do with thickness as it does hardness. Like how you can smash automotive glass extremely easily with a tiny chunk of ceramic from a spark plug.

      There are temperature treatments that can be done to glass that purposefully induces permanent tensions and compression forces in the glass that makes it stronger. But you need a big enough piece of glass to do that.
