More or less matches my experience, including having been raised eating on Corelle dishes. They'll take drop after drop and then suddenly the last one leaves a giant mess to sweep up. Every time.
I have discovered that if you leave a Corelle plate outside during the winter, in the spring it will be broken into little bitty pieces. It can't handle the freeze and thaw cycles which surprised me.
A little bit of on purpose, a little bit of not caring. I had it underneath a small plant pot and just left it out there. I found it interesting that it can handle hot thermal stress (expansion) but not cold (contraction).
