It is my understanding that normal glass is a super-viscous liquid at
normal ambient temperatures. This is because glass has no regular crystal
lattice structure (something that it chracteristic of the solid state).
As a result, glass obeys the properties of a liquid, and will eventually
conform to the shape of its container. Heating glass merely decreases its
viscosity, and its liquid qualities become more apparent.
I have also read that older glass panes show marked thickening towards the
bottom.

Well, your understanding is wrong, wrong, wrongity wrong. Your
punsihment for reviving The Thread That Will Not Die is two fold:
1) First do a search via Deja News for afu threads with "Glass" in the
subject line, read EVERY STINKIN' ONE of 'em. Pay particular
attention to a few lengthly post by Ian "Man of Many Talents" York.
(I'd send you to the archives, but they seem to be a bit under-the
weather, and not up to a visit right now.)
2] Park yourself in front of a convienient window. Remain there for
200 years. Report back if you see the glass flow.

You may well have read it, that doesn't make it any more true though.
TRy checking the FAQ or even the archives at

you will see as have many others that glass is a SOLID, the whole
liquid story is just that, a story.

Steve Writes:
Glass is a supercooled liquid with the properties of a solid. In fact
glass displays nearly elastic behavior! If you introduce a stress to an
elastic body not beyond its breaking point, and then remove that stress,
it will resume it's original shape. This is well documented in glass
technology texts and materials science texts (I can cite texts but they
are buried in my closets). Glass has short and medium range crystal
structure that fails to fill the definition of a crystalline material.
In a crystalline material, you can predict the occurence of a molecule or
atom of the material from the position of any other molecule or atom
(that is a really rough definition).
Glass does not flow. The only proof of glass "flowing" is some old
stained glass in church windows. What no articles mention, however, is
that primitive glass making techniques were shoddy. They couldn't make
flat panes of glass with uniform thickness. What the could do, however,
was gauge the thickness of the glass with measuring devices and then
align the pieces of stained glass with their thick ends down to increase
stability and artistic appearance of the window. This gave rise to the
UL that glass flows.

Joke's on you, Richard...Or should I say, Ted's crying wolf, as it were.
Anyway, straight from my recycling pile: NY Times, Wednesday April 2, page
C1: Headline: "Where No Candy
Has Gone Before:
Light as the
Secret Ingredient"
The "mad scientist" is Eric Begleiter, who had the idea for holographic
food 10 years ago, when he was a fellow at MIT. He's now the President of
a start-up company in Cambridge (MASS) called Dimensional Foods, and owner
of another company, Lightvision Confections (http://www.lightvision.com),
that actually makes the candies.
The first product, currently on the market and illustrated in the article,
is a Star Trek lollipop, with holographic images of Klingons, etc.
There are a lot of other cool details in the article, which may still be
around on the Times web site (http://www.nytimes.com; the proof is left as
an exercise for the reader). The glass flowing remark (on the inside
continuation page, page 6 in my edition) is in the context of the
difficulties of actually making the chocolate holographic.
So, I would venture to say that if anyone's trolling here, it's not Ted.
And, if Ted is being victimized here, he's in good company.

I've read that some older glass panes show marked thickening towards the
bottom. You have too. If you haven't:
"Some older glass panes show marked thickening towards the bottom."
Now you have. (I admit, I weaseled with "Some".)
In fact, I've seen old glass thicker at the bottom. Maybe you have, too.
However, the persistent, irritating datum is not that there exist
panes that are thicker at the bottom, but that their existence "proves"
that grass throws.
Grant Hughes may or may not be a horrible man, but his having said that
he had read that does not indicate one way or the other.
The rabid nit-picker could argue that the word "thickening" reveals a
bias toward its being a result of an ongoing process. From the rest
of the article (concealed in "[snipsnap]" above), I'd think that would
be an accurate assessment. Grant Hughes probably believed that the
thickness had increased over time. Perhaps he still does.
If so, the "class doesn't show" camp believes that he is mistaken in
that regard. But a lot of them are meany-heads, anyway.

I think the proper question is, how can one post be called a waste
relative to any other post?
Some threads will always be with us. Patience is a virtue. I am at least
half as smart as MattMcIrvin, I got all the way to age 40 and through a
chemistry degree from a prestigious university and I had to learn about
glass from the Usenet. Although I do, seriously, understand that the
unaware (like myself) were created to provide foils for the slashing wit
of afu.

One of these references (Ernsberger, F. M. In Glass: Science and
Technology; Uhlmann, D. R.; Kreidle, N. J., Eds.; Acad.: New York, 1980;
Vol. V, Chapter 1.) explicitly says:
There is a widespread opinion that glasses are supercooled liquids and
therefore have a finite viscosity at ordinary ambient temperatures.
Stories are told of glasses flowing under their own weight: of ancient
windowpanes that are thicker at the bottom; of glass that has sagged in
storage. These observations must find other explanations, because
glasses of commercially useful compositions are in fact rigid solids at
ordinary temperatures.
More:
Glass is an amorphous solid. A material is amorphous when it has no
long-range order, that is, when there is no regularity in the
arrangement of its molecular constituents on a scale larger than a few
times the size of these groups. ... A solid is a rigid material; IT DOES
NOT FLOW WHEN IT IS SUBJECTED TO MODERATE FORCES. More quantitatively, a
solid can be defined as a material with a viscosity of more than about
10^15 P (poises). --Doremus, Glass Science, 1973
The highest observed macro stress level acheived is only 20% of that,
and was done to a glass fiber (as close to flawless as we can get).
Therefore, we can not apply a yield stress to the glass that could cause
it to flow without first breaking our sample. If, somehow, magically,
you could apply a stress to an unflawed sample, then the observed
plastic deformation (e2) would be roughly 1/15000 the magnitude of the
applied stress (in kg/mm^2). So even if you could magically apply a
yielding stress, then you would not be able to measure the deformation.
This applies to glasses below 600C (or 270C for infinite time lengths).
--Elastic-Plastic Problems, B.D. Annin and G.P. Cherepanov, c 1988, The
American Society of Mechanical Engineers (paraphrased by Scott
Sehlhorst)
We use glass in this case, not because it is transparent, but because
its rigidity and permanence of shape are better than steel or concrete.

2. "A solid is a material whose shear viscosity exceeds 10^14.6

Longman Group Ltd, 1983; ISBN 0-582-44636-8), from the definitions
section, p. 5
There's only one article that even remotely supports your contention, and
its very support actually refutes it, because it concludes that glass
could only flow if several real-world considerations were ignored: ou'd
have to have a piece of glass several miles long to observe any flow, and
it would take several million years for the effect to manifest itself.
They dismiss with a wave of their hands the objection that a piece of
glass that huge would crumble under its own weight, destroying the
evidence in much less than a million years . ("Gravity-Induced Flow of a
Structural Glass at Zero Temperature", by Clare C. Yu and S. N.
Coppersmith, from Journal of Non-Crystalline Solids, 131-133, 1991, pp
476-478). This is taken from Ray Depew's comments on the article; use
DejaNews to find the whole thing.
Further, the claim that people make to support their contention--that old
windows are thicker at the bottom--is trivially refuted, and so there is
no evidence that glass does flow. Two people in the past couple of weeks
in this thread have actually gone and looked at the windows in their old
houses, or their old cathedrals. Stephen Tonkin
<as...@aegis1.demon.co.uk> determined that "it is twaddle. In the
buildings I looked at many, but not all, of windows of uneven thickness
have the thicker glass at the bottom. Some have it at the side. A few
have it at the top." Charles Dimmick (dim...@ccsu.ctstateu.edu) said
"The south-facing windows of St. Peter's Church, Cheshire, Connecticut,
built in 1840, have panes that undulate, as though they had flowed. The
problem is that while most of the panes have undulations that would
indicate downward flow, 1/6 of the panes have undulations that would
indicate sidewards flow, and a few of the panes have undulations that
would indicate flow at 45 degrees to straight down." They therefore agree
with medieval stained-glass-window restorer Peter Gibson, who said that
"in a lifetime of dismantling medieval glass [windows] he had seen
hundreds of pieces that were thicker at the top."
This also agrees with the interpretation that the irregularity of the
glass is due to the Crown glass manufacturing method, as described in
(Muspratt, S. Chemistry Theoretical, Practical & Analytical as Applied
and Relating to the Arts and Manufactures; Mackenz)ie: London, 1860; Vol.

For some reason, tonight I noticed that Ian's post was 170 lines long. Now
it occurs to me that this is bigger than some FAQs I've read, and this is
mostly a list of pointers to yet more sources. Why do people fight such
overwhelming odds? I know this has been discussed before, but KEE-rist
that's a lot of compelling evidence.
Can we get this on some International popular media (I know, I know. I mean

can get this into the public brain, there will be a hope, however small,
that when my children grow up they won't have to read this thread (or use
whatever the popular UI is at the time).

If you lump everyone in that bucket that is tired of watching this thread

I can see maybe getting upset about Madeleine's response (though if you read

like that). On the other hand, Judy was incredibly polite about it, and
even tried to offer you a free clue. You come back with the same spastic

I know how to use a killfile. I don't use it on threads, because the title

I did some remodeling work on an old German farm house, built about
150 years ago. I should point out that I have not proof the glass was
original, but it was pretty poorly made, with lots of flaws, and
inconsistancies in thickness. However, the glass that was left, (most
of it broken) WAS thicker on the bottom. Someone else posted that
this was because of poor glass making. But this doesn't explain
another fact I observed. Some of the glass was not only thicker at
the bottom, but thicker that the crevace that was holding it and was
"oozing" over the edge ever so slightly, like 1/8 to 1/4mm or so.
This "oozing" was VERY consistant over the length of the pane.
Any ideas what could cause that?

My entire post was simple stating the facts as I observed them. Which

cause the effects I saw. I can see now that your posts are about

So glass is a flowing solid or do solids flow, generally? Are you
arguing that window makers selected panes to appear wavy and to
mismatch other windows on purpose?
All over the Bay Area are window panes as you describe that were
installed in the 1920's, for example. Was glass making really that
shoddy in the 1920's? How come nearly every old house has mixmatched
panes, some clear, some a little wavy, and some rather distorted, in
a random pattern, as if contractors were incapable of telling the
difference, or was this simply a style of the times?

Madeleine offered several alternate explanations that are at least as
likely as the notion that your glass flowed. Judy pointed you toward
several more general treatises which might help to explain your situation.
If you choose not to accept their explanations, then by all means search
for one that satisfies you. But search somewhere else.

If glass flows, then the references I append here are in error. Since
these include references to articles in peer-reviewed journals by experts
in materials science, it's most unlikely that glass does flow. Moreover,
included are references which provide both a refutation of the common
claim, and a satisfactory explanation for those observations which are not
refuted.
If you chosse to continue to claim that glass does flow, please explicitly
refute these specialists, point by point, without making use of claims
which they already debunk.

Dear Mr Lemons III,
Welcome to alt.folklore.urban. My name is Harry Teasley, and I am the
Regional Director of Flamefests, Snits, and Large Misunderstandings for
AFU GmbH. It has been brought to my attention that your participation in
one of our "red flag" threads has contravened the Wiener Act, specifically
sections IV and VII ("Inanity" and "Repetition").
Minor isolated infractions are ofttimes not prosecuted to the fullest
extent allowable, being possibly attributable to random chance or abnormal
delusionary posting. However, the mainframe at One AFU Plaza, which
filters all AFU postings and categorizes them for research purposes,
marked your posts as abnormally rich in Wiener Phrasing, and it was
automatically referred to me.
Your abnormally high per-word count seems to be due to your incredibly low
posting volume up until now. Achieving as high a Wiener Number as you
have in such a short time was thought to be beyond to scope of new
posters, but you are clearly no ordinary newbie.
You are invited therefore to be fucked and thrown to the wolves.
Regards,
Harry Teasley

Thank god... I don't have to bother with your useless posts either...
I think I finally figured out why the ratio of bone-head, know-it-all
replies is so high in this group...
For some reason people who have nothing better to do than wait for
someone to ask a question about something they can pounce on and then
call them stupid for not knowing the right answer seem to be drawn to
this news group because the very subject matter provides them with
fertile ground for their ego-enhancing drivel. Add mister spelling
bee himself, "Hans Derycke the unknown", to that list... He is such a
sad fellow that he not only has to trounce people for their lack of
knowledge, but further enhance his pitiful ego by picking on typos as
if they were heresy.
All I can so is my kill file for this group is ever growing ...
Steve Writes:
Yes they were. And why do you assume that wavy glass is not clear.
Clarity has nothing to do with waviness. Do you want a dissertation
here? By the thickness defniition of waviness, prescription glasses
could be considered wavy, but they are arguably clear.
Thanks,
Steve
There. You have it right there.

Actaully, in the 1920s people still had a choice between old,
imperfect, cheap glass and modern, more expensive flotation glass. Many
chose the former for cost reasons. The flotation process has now become
so inexpensive, and, because it was more labor intensive, the old
process so relatively more expensive, that it now probably costs more
for the bad stuff than for the good stuff.
You seem to be a tad ignorant of fairly recent history and lifestyles.
Of course, to me the 1920s ARE fairly recent history, although still
before my time.

Sorry, John, but I think you're mistaken that the effect you
observed is due to flow. It's possible that the glass was
made in that shape and/or that the sill was made to enclose
the existing shape of the glass. The optimal shape for
holding that pane would, of course, give the idea that the
pane had flowed. My father restores antique furniture and I
have seen examples of tapered, bevelled and chamfered glass
which were quite convincing until you noticed that the same
feature occured at the top of the pane.
By some mystical coincidence, nobody has ever produced any
sideways photograph of 'oozed' glass, and it's rare to find
builders or renovators equipped with a micrometer and the
urge to measure the thickness of a pane at various points.
About 20 miles north of my parents' place is a Roman site
which has some fragments of vertically-mounted glass which
show no sign of having flowed -- however I have no evidence
that they're remained vertical for 2000 years.
[Note to some other responders: if you can't comment on the
points raised, an appropriate response is 'read the FAQ',
not insults. Note to John: replying to written insults
with more insults has little effect.]

Your understanding is wrong. Glass is not a liquid, it is an amorphus
solid. Yes it has no crystal structure--neither does obsidian rock.
Rock does not flow under pressure at STP (standard temperature and
pressure for those who are debating a scientific topic without having
taken elementary school science) and neither does glass. All
materials have a viscosity--however that viscosity in solids is so
large that the bonds holding the material together would break before
there was enough force to overcome the high viscosity and cause flow.
The viscosity of glass exceeds the min. viscosity required of solids
which is 10^15 kpoise at STP..

No. The irritant is not that people ask bone-headed questions. The
irritant is that they are either too stupid or too arrogant to know
it's a bone-headed question. And when even gently pointed out, they get
even more stupid and bone-headed. Just about everyone regularly in this
group has probably had the same treatment at one time or another.

First point: how do you know that the clear glass and the wavy glass
are the same age?
Second point: yes, the glass making techniques used in the 1920's
produced wavy glass. Chances are that glass mannufactured in the
1920's was manufactured by rolling which left the waves you now see.
There were basically five methods of making plate (window) glass:
- By casting: molten glass is poured into a mold and later polished.
The glass produced is often not very transparent and contains many
defects. This method was used by the Romans and survived well into
the nineteenth century.
- By the "crown glass" method: molten glass is blown into a large
sphere. The sphere is spun and a small hole is opened in the bottom
of the sphere. The sphere opens into a disk of relatively uniform
thickness.
- By the "cylinder" or "broad" method: molten glass was blown into a
cylinder which was cut open to produce a glass plate.
- By mechanical rolling: molten glass was pressed between rollers much
as sheet metal is produced. Some imperfections were still present in
the glass.
- By the "float glass" method: molten glass is poured from the furnace
onto a vat of molten metal. This allows the glass to distribute
itself evenly resulting in perfectly flat glass. The glass is free of
the defects produced by the previous mechanical processes. The float
glass method was invented 1959 by Alistair Pilkington of the
Pilkington Glass Company.
Here's a short time line showing when these methods were used:
4000 BC Glass manufactured in Near East.
1668 Broad glass method invented in St. Gobain, France.
1870 Rolled glass produced by Chance Brothers
1898 Wired glass first made
1910 Mechanical cylinder drawing machine
1913 Sheet glass drawn mechanically by Fourcault machine straight from the furnace
1918 Bicheroux process for casting, grinding and polishing of plate glass
1937 Pilkington twin grinding and polishing of plate glass
1959 Float glass method invented by Pilkington Bros.
My house, which was built in 1929, has wavy glass. Some of the waves
are horizontal, some are vertical, and some are diagonal. This is
just an artifact of their manufacture, not due to "flow".

I suggest you stop worrying about the sex lives of famous people and
spend more time worrying about your education, which you have just
demonstrated to be somewhat lacking.

Boy now I feel left out. I tried to be flamable by posting to the virgin
birth thread and the peeing on electric fence thread. I know I usually
sit in the corner and just watch, but no-one ever wants to play with me.

Look, I don't really care if you want to post yet another unsubstantiated
statement that glass flows, and I'm only slightly annoyed at your
attempt to continue the pointless JLC discussion; but I won't sit idly
by while you insult the good name of sewergators. Apologize immediately,
you vermin.

Not that I imagine anyone's reading this thread anymore, but
you misplet "metastable". Nit-picky, to be sure, but
thermodynamically metastable states are stable with respect
to small fluctuations, but do not represent thermodynamic
equilibrium, that is, they do not minimize the free energy
of the system. Unstable states are states which have
zero or negative restoring forces with respect to
perturbations.
Glass is metastable. So is diamond. Metastable systems
generally do not have infinite lifetimes, and tend towards
true equilibrium, but the time constants involved can be many
orders of magnitude larger than the age of the solar system.
And, just because the AFU archive (at
http://www.urbanlegends.com) is down, and it hasn't come up
once in the seventy-four posts I read, I will repeat (from my
fallible memory) an item that's mentioned there which is the
best debunking of the "supercooled liquid" terminology I've
ever seen, namely that disordered solid glass can be obtained by
some kind of sputtering and/or vapour-deposition process in
which the liquid phase is never present.
