Very true.Originally Posted by bstreep
If you check the thickness of glass on a very old building that's windows have been there for quite a while the glass pane will be thicker at the bottom than on top. Over many, many years this will continue to happen.

You know, I started this... But, it appears as though the "glass is a liquid" MAY be an Urban Legend... I got to thinking about my OP on this, and then remember hearing somewhere that it might not be true, so I did some searching:
Scientists aren't in agreement on this, BUT:
Most agree that glass is actually an amorphous solid, rather than a liquid and,
There is a belief that the reason why old glass is thicker on the bottom is that glass making was very imperfect, and the heavier end (thicker end) was installed on the bottom because the panes were more stable that way...
Oh well!

I can agree with glass being an amorphous solid, that is a solid that does not have a crystalline structure. Only recently have they added the two subclasses of solids, amorphous and crystalline. Prior to this glass could not be considered a solid because it didn't and a definite shape with a crystalline structure.
