Glass

Hi,

Are there any glass merchants on here or anyone that has bought glass on its own? I'm just looking for some rough prices of varying sizes of glass. for instance 1m squared.

Thanks

Baxter

Depends on the type and thickness you want

Baxter · 29 Nov 2006 at 21:11

5mm thick, hardened i think

Glass is a liquid.

no, glass is a liquid, not a solid

I got mine from a place on an industrial estate which I got from the Yellow Pages. It was toughened glass and they cut it, smoothed the edges and even gave me little sticky pads to rest it on.

Maybe in Crazyland but here on Earth it is very much a solid.

supercooled liquid is still a liquid

Frozen supercooled liquid is very much solid

5mm is unusual you can get it but because its not as common it more expensive

6mm toughened is more common and will be under £40 /m2 inc vat

I stand corrected by Wiki

Actually it's an amorphous solid

I'm not sure why people call it a liquid, I suppose it's cos it hasn't crystallised and so there's no definite point where you can call it 'solid', but there's no evidence that it flows as far as i'm aware. I've seen glass that's thinner at the top than bottom, it's not because it's flowing but rather because of the technique used to make it, it's always been thinner at the top.

That's just super.

has the process of glass not changed throughout the course of time - i read some where that old panes of glass (hundreds of years old) that had been removed showed the same thing - thinner at the top wider at the bottom?

this has been shown to be false many many times - glass is a solid and does not 'flow' like a liquid even over several hundred years.

its one of those scientific urban myths (like the average person only uses 10% of their brains) that everybody believes but is, in fact, complete crap.

as stated on the link provided above, if thats true why aren't ancient glass artifacts just pools, or atleast slightly warped?

The chances are that the pains of glass were that shape already due to the way they were blowen

As an ex-Glazier I can assure you that glass is very much a solid and I really do have the scars to prove it

It also has a personality and it's not a nice one. It goes out on Friday night just to have a fight, and drinks alcopops.
