Technical terms aside, if left on it's own over a long enough time scale will or won't glass flow??
I'm trying to understand whether the urban legend is:
- that glass is 'classified' as a liquid or
- that glass flows over long (long long) periods of time.
**also, to the debunkers who claim thin-at-the-top-thick-at-the-bottom glass in antique windows is a result of an old standard glass-creation process, show me (or even tell me there exist) antique windows where they are thick-at-the-top-thin-at-the-bottom and i see no reason not to believe you.
