Where you say thermal expansion in #3, you really should be saying differential thermal expansion. The glass, once it comes to thermal equilibrium, will be of the same shape, albeit a few tenths of a thousandths of an inch bigger in diameter, as at the other temp. It's while the temp is different across the thickness and/or the diameter, you get stresses that deform the glass.
