Regarding freezing, I think one should differentiate between the

crystallize. Glasses are still liquids when called solids because they
still flow and there is not a demarcation in their properties.

There seems to be quite a wide acceptance of the idea that
solidified glass flows. This position is supported
by the assertion that medieval church glass is thicker at the foot.

The creep, if I can call it that, apparently takes place over very
much longer time-scales, so the concept is not so clear cut.
