Yes old thread and old question. Glass is not a liquid at comfortable human temperatures. The often cited wavey glass pane windows and bluges i the panes are falicies. Look closely at an old pane of glass that is supposedly melting. Sometimes the thickest points are the sides or top of the pane. This discounts that glass is liquid and boing pulled down by gravity. Unless of course it was mounted in one of those obsolite anti-gravity window frames.
The ones that are thickest at the bottom should show the glass melting onto and starting to wrap around or puddling up on the windows frame or stained glass lead framing. Yet it does not!
Glass panes that are a few centuries old should be paper thin at the top and all puddled up at the bottom by now, but are not.
Glass pane munufacturing was not perfected and commericalized until the late 1950s. Any glass panes you see from before then will have many optical imperfections that are noticeable when looking through them.
