Is solid glass liquid????

Question

I was told that in a window when time passes the glass will start falling and making a glass thing on the bottom of the window something like that

Answer 1

Glass belongs to the group of crystals called amorphous solids.

Amorphous means shapeless.

Glass do not have a definite melting point.

Only by melting the solid glass, glass can be converted into liquid.

Answer 2

No. It's an old wives tale that started from the observation that stained glass windows in cathedrals were thicker at the bottom than at the top. Nobody with any sense ever gave it any credibility because there was no distortion of the images that would have occurred if the glass had settled. The glass is thicker at the bottom because it was designed that way. The bottom had to be thicker to support the weight of the window.
Glass is not a crystal, so it can be deformed by pressure, but that's a long way from being a liquid.

Answer 3

I've been working with glass for about 18 years. It's hard to say for sure if it will settle down over time. By over time I mean 100 years.
You can see that 100 year old glass is thicker on the bottom then the top but mostly because they way the use to make glass.
They use to dip a rod into molten glass and slowly draw it up and cool it. They called it drawn glass.
Making it thicker in some spots then others. Also the components they use to make glass have changed over the last 100 years

Now a days window or float glass is made by floating it on a liquid tin which levels it almost perfectly. The compounds have changed as well, a bit anyway.

That being said if it does settle you won't know in your life time, but I really don't think it does not the way it's made these days anyway

Answer 4

The glass is a solid, but solids also diffuse like liquids. The glass, after a long period of time will be slightly thicker at the bottom (this is more common in older glass) as gravity 'pulls' it down, but as glass techniques have become more refined this has been reduced. Go look at the stained glass in a church for an example. The only was to see solids like this move quickly is with radioactive material.

Answer 5

Glasses are amorphous solids. there's a needed structural divide between amorphous solids (alongside with glasses) and crystalline solids. Structurally, glasses are comparable to beverages, yet that doesn't mean they're liquid. this is a threat that the "glass is a liquid" city legend originated with a misreading of a German treatise on glass thermodynamics.

Answer 6

It's a fluid (due to it's structure) rather than a liquid.

Window glass can last several hundred years. Original glass in old houses is always more valuable as the imperfections are said to add charm .

Answer 7

Solid glass is a fluid(a more general word for liquid) with a very very high viscosity and a very very slow rate of flow and what you were told is true

Answer 8

Yes solid glass is liquid.
It"s flow rate is very slow.
A fraction of an inch in 100years!

Answer 9

No,glass is made by sand heated to an extreme temperature.

Answer 10

first of all, glass isnt a SOLID, its FLUID
it flows but very very slow.
it takes some thousand years for the molecules to move a considerable distance
