I have been told that though glass seems like a solid, it is somehow, in theory, a liquid -- but is just somehow a liquid that is so thick that it appears to be solid. (Of course --- if this premise to my question is an urban myth then let me know, and that will qualify as an answer.)

My question is this ---- by what factor would you have to slow down time if you want regular water to appear as-though solid to you the way glass does?

Contrary to popular misconception, below a specific temperature, glasses do not flow. At all. A glass by definition is a solid sans repeating crystalline structure. Anything which flows (see "pitch-drop experiment which drops every 80 (or something) years") is a liquid, however viscous. Liquid glasses tend to have reasonably high viscosity, but once they freeze, they're solid and do not flow or deform.

So the strict answer to your question about water and time is that you'll need to freeze time to make liquid water behave like solid glass.
