For something so commonplace, glass is actually an incredible mystery; an enigma of physics that has defied understanding since humans first encountered it millennia ago.
The reason is this: glass is no ordinary solid. But nor is it a liquid. It lies somewhere in between, a strange hybrid known as an amorphous solid – something that's firm to the touch, yet down at the atomic level, it actually behaves rather more like liquid.

And others assisted with the fake bit about windows being thicker at the bottom...
Young grunt an easy target! But tough.
By the way, old glass was spun as a disk, thicker at the outside edge...
Frank, get it right this time.
So is neither masculine or feminine but neuter......It’s an IT.
I have always recalled back in high school in the 60’s about learning glass was a liquid and they used glass from old buildings as evidence where some how it sagged over time.
Great to hear this. There are some good places on this planet where the physics can and should be tested...
Places needing a glass testing.
My nephew told me once that his science teacher told him that glass wasn’t a solid. I said his science teacher was stupid. It turns out I was.
Look, the physics of glass (and everything else) can be explained by Global Warming. Glass used to be a solid. But the Earth is much warmer these days. So now glass is a liquid.
Where do I go to collect my Nobel Prize?
Don’t know why people think glass is so mysterious. It’s so transparent.
I do not know how much it sags over time, but I can tell you from experience that it is harder to cut up an old piece that has been in a window for a long time than a new piece of glass.
Ye canna ney break da laws of physics laddie.
For window panes?
I think it started out as a cylinder, as for say a glass bottle made by a glass blower.
While still hot, it's placed on a cooling table with an engraved template, for wont of a better description.
The ends are cut to the template, and the cylinder split and laid out, then also cut.
If you look at old windows, you'll see that they consist of small panes. I'm guess that pane size was deemed the most efficient for production for glass blowers at the time.
MORE POWER, Scottie.

I once saw wavy glass in an OLD building and asked my dad why is that? He said “ Because glass is liquid, stupid.” As a four year old, it made me think and I learned from books.
back in high school in the 60’s...
Some people claim that stained glass windows in old churches are thicker at the bottom than at the top because glass flows slowly like a liquid. We’ve known this isn’t true for quite some time now; these windows are thicker at the bottom owing to the production process. Back during medieval times, a lump of molten glass was rolled, expanded, and flattened before being spun into a disc and cut into panes. These sheets were thicker around the edges and installed such that the heavier side was at the bottom.

Glass is lucist.
I live in a house over one hundred years old, replaced all the windows but one, and it is wavey.
Methinks it was wavey, the day they installed it?
Further study is required. Cheers!
This is where Obama got people confused.
He said transparent when he meant translucent!
Wonder what happens to glass in a super cooled state?
Actual solid? Might have interesting properties.
Dude, do NOT give that glass to someone who is tripping!
