Talk:Glass

Template:WP1.0

Intro section: unsupported or original research?

Quote: > Strangely enough, to make good quality glass, you need to ADD glass to the mixture (or cullet) before it gets to the molten tin furnace to float on. Tin when molten is perfectly flat and glass floats on top as it is lighter than tin, thus giving glass the "float glass" name sometimes used instead of "raw glass".

The whole wording makes me uneasy, but we need supporting evidence first before we talk about cleaning up the wording. As a matter of fact, does the article really need to explain in this much detail how to make glass? —The preceding unsigned comment was added by 204.96.216.30 (talk) 13:13, 1 March 2007 (UTC).

History Section: UFOs?

The discussion of UFOs in the Americas and their connection to glass seems to me rather speculative. It should probably be removed if no reliable source can be found.

MS Excel

"Reduction of the sum of square errors using the Solver option in Microsoft Excel with the glass components as variables" - is Excel uniquely good for this? Otherwise it doesn't seem neutral to mention a specific piece of software.

One Correction Should be Made

In the picture captioned: Hand-blown glass beads and pendants illustrate some of the myriad colors and shapes of glass art. The actual process is lampworked (also known as flameworking), not blown. I have no idea how to go about editing the main page without screwing it up, so someone more knowledgeable should change it. 68.144.87.169 05:14, 30 April 2007 (UTC)

Solid or Liquid?

this is gonna sound retarded to most people. but is glass a solid or a liquid? i assumed it was a solid until my science teacher (he's not one of those insane teachers, he has his facts straight) told me it was actually a super-sedated liquid. i also noticed on the page it said it was "of arguable phase". does that mean they dont know what it is? --Late Leo 20:46, 9 April 2007 (UTC)

Yes glass is a liquid but its flow speed is less than 1mm in about 100 yrs —The preceding unsigned comment was added by 84.250.110.93 (talk) 14:42, 9 May 2007 (UTC).

read the article again you might learn something...glass a does not flow at all there is no evidence of it...the anecdotes of evidence are not proof -- unsigned edit by 24.222.118.137

Glass, as far as I can discern, is an amorphous solid. The idea that it is a liquid is widely believed, since there are many surprising facts in science which refute common belief. Anyone who refutes such a fact can be said to merely speak from ignorance. Consider also the widely-held belief that a duck's quack does not echo. How can the average person expect to refute either this, or the idea that glass is not a liquid? --Jonathan Drain 00:13, 21 August 2007 (UTC)

Sections deleted

A couple of months ago, with this edit: [1], a big chunk of useful and readable info on glass properties and ingredients was removed and then replaced with the way-too-technical "calculating glass properties" section. The info should really be re-integrated back into the article, and the calculations shunted into some other article. --Bob Mellish 08:15, 15 April 2007 (UTC)

Oh you haven't noticed? no one notices/gives a shit. this happens everywhere all the time. most of the time no one ever notices at all. I'm close to leaving wikipedia due to this ceaseless unchecked vandalism.--Deglr6328 02:55, 4 July 2007 (UTC)

Bob, I recommend that you do so. Any edit that improves the article, I'm all for it. --Jonathan Drain 00:19, 21 August 2007 (UTC)

Proposed WikiProject

So far as I can tell, there does not seem to be an extant project which deals with this article, or several other similar articles. On that basis, I have proposed a project at Wikipedia:WikiProject Council/Proposals#Chemical compounds and mixtures which might deal with subjects such as this. Anyone interested should add their name there so that we can know if such a proposal would receive sufficient interest to at least potentially stay active. Thank you for your attention.

How is it made?

I came to this article to find out how glass is made, and was surprised that it does not explain the production process, only the composition. I think this would be very useful information to include. Thanks. 134.225.1.162 12:56, 15 May 2007 (UTC)

Archive Created

I've taken the liberty of creating an archive of the old discusssions, as this page was getting a bit lengthy. I don't believe that there were any active discussions in the material that I archived, but if there was, please accept my apologies and feel free to revive it. Thanks! -Sarfa 17:05, 4 August 2007 (UTC)

Non-silica based glasses

Although something does not need silicon dioxide to be a glass, there is very little in this article about non-silica based glasses. Certainly, as what most people think of when 'glass' is mentioned, silica based items should form the bulk of the article, but I was hoping for at least a section covering 'glass' in the more general use. -- 21:32, 27 August 2007 (UTC)
