but that’s the thing. They simply don’t. They might shift slightly if it is kept for prolonged periods of time at just under its melting point temperature. other than that, it is a very stable substance. Its molecules do not move similarly to a liquid at all. It’s an amorphous solid.
they were made that way. ours today are very even because we use a different process (layer of molten glass on a layer of molten tin, makes a perfectly smooth sheet of glass) They did not have our technology back then. So their sheets had uneven thickness. Also, some windows are thicker on top, not t the bottom, because they happened to be mounted that way and they did not change shape.
I said “similar to a liquid”. Everything I looked up said it is not a liquid, but that it’s molecules DO move similarly.

What’s the explanation for windows looking like they’re melting then?
