    Stephen Fry says it's an amorphous solid.
    As the song goes,

    There is no clear definition of the distinction between solids and highly viscous liquids. You can argue either way.

    Doesn't a viscous liquid have to behave differently at different pressures? Pushing lightly against my window doesnt seem to be doing much, hold on i'll push hard.....

    cba looking it up now but IIRC the way old cathedral glass bulged at tbe bottom has more to do with the way flat glass was made than from flow. You glassblow a bottle, and then burst it with a tool and spin very fast to get a glass disk. BTW: The bullseyes are at the centre and were not used except by the very poor, so they are not traditional for pubs.

    ...and that's all relative to ambient temperature and pressure. The molecule remains the same, it's just that it's environment determines how those molecules and the atoms making them up behave.
    If we were to think along these lines then every single element, compound and alloy could be said to be any of the 4 states of matter.
    Glass being a liquid? I'd never heard of that before so I presumed it was BS straight away, since it's the sort of thing that would peak my interest.
    *deep breath* NNNNNNNNNERRRRRRRRD!!!











    Sorry. I don't even understand the most basic scientific theories and regularly failed science at school, having to drop down to the ordinary level paper in Junior Cert... so I'm insecure on that front. :o

    Yeah, but the point is whether something is a liquid or a solid or a gas is usually dependent on the temperature. It was just to point out that substances can easily change state, it's not so confusing that glass is made from sand.

    there is such thing as non silica based glass also

    lol nerd? As someone who failed chem in my LC, I'll take that as a compliment :D I've just always been fascinated by chemical elements from a young age

    Water is a simple concept to illustrate my point: put it some place cold and it turns to a solid, at very low temperatures it can be harder than steel.
    Bring it to a point between 0 and 100 celcius at normal pressure and it's a liquid.
    Bring it above 100 and it vapourises, turns to steam.
    As capt said, place it in a vacuum and it will also vapourise.

    The point being that almost anything can be said to be a liquid, gas or solid (not sure about plasma) depending on it's surroundings. Any metal when molten is a liquid, any gas when cooled sufficiently is a liquid.
    These are pretty simple concepts...

    I know that glass is a liquid, but it's made from a solid, so something is amiss somewhere alond the line.


    Ice is made from Water. Water is a Liquid Ice is not. and there is noting amiss. Its just changing states of Matter.

    remember the Liberty ships in WWII they had very brittle steel below 9C and many cracked in half in artic waters. Hardness at low temperatures is not always a good thing

    and mercury is a great metal to make bells from

    temp is a funny thing magnetic ones aren't above the curie tempertature and uranium/plutonium change volume because with termperature

    If you smash a piece of glass into a million pieces.....































    Why don't you get a puddle?

    Glass is neither liquid or solid. Glass is a gas.
