Is glass really a liquid?
« on: 24/02/2010 16:13:25 »
Because I've heard different views expressed on the subject. Dr. Karl on Radio 5 live claimed glass is a solid a few months ago, but I heard a guy on last Sunday's Naked Scientists claiming it is a liquid, which is what I had heard before, and believed. So can someone please help clear this up. Is glass, or is it not, a liquid?

It depends on the meaning of the word liquid.

Does the same go for the meaning of the word solid ?

...if the windows found in early Colonial American homes were thicker at the bottom than the top because of "flow" then the glass found in Egyptian Tombs should be a puddle.

Isn't that a "pane in the glass"?

The claim that glass "flows" over time to become thicker at the base of windows is a myth.

We debunked this one on an episode of Breaking Science last year:

Glass is an amorphous solid. However it may also be classified as a rigid liquid because the molecules have not crystallized

Is that  "Glane in the pass?"

Glass has a characteristic, yata, yata, yata!
It is described at this site...
