Fact or Fiction?: Glass Is a (Supercooled) Liquid
> http://www.scientificamerican.com/article/fact-fiction-glass-liquid/


> In medieval European cathedrals, the glass sometimes looks odd. Some
> panes are thicker at the bottom than they are at the top. The
> seemingly solid glass appears to have melted. This is evidence, say
> tour guides, Internet rumors and even high school chemistry teachers,
> that glass is actually a liquid. And, because glass is hard, it must
> be a supercooled liquid.

> Glass, however, is actually neither a liquid—supercooled or
> otherwise—nor a solid. It is an amorphous solid—a state somewhere
> between those two states of matter. And yet glass's liquidlike
> properties are not enough to explain the thicker-bottomed windows,
> because glass atoms move too slowly for changes to be visible.
