Solid?

I thought the process of relaxation showed that glass isn't really a solid or a liquid. 2600:6C44:6E00:178B:FA4:406B:E95A:EC85 (talk) 08:48, 15 June 2023 (UTC)

:No, that's a myth, as explained in the article. Polyamorph (talk) 08:55, 15 June 2023 (UTC)

Semi-protected edit request on 9 August 2023

In the intro, please change "3,600 BC" to "3600 BC". Commas aren't usually used for digit grouping in year numbers (it's not 2,023 right now), and they're not used in any of the other pre-1000BC years that appear in the history section. 123.51.107.94 (talk) 23:31, 9 August 2023 (UTC)

Wrong date

The Roman cage cup photo under the History section should say 4th century C.E., not B.C. 2601:19D:403:DFE0:257D:4F2B:5656:37FC (talk) 05:34, 21 December 2023 (UTC)

:{{Done}} kind of an embarrassing mistake. Recon rabbit 12:38, 9 July 2024 (UTC)

Edit suggestion

in the image of the amorphous structure of SO2, it says the red atoms are silicon and the blue ones oxygen. It’s the other way around. One silicon atom is bonded to two oxygens it shares with another silicon atom. Geefkip (talk) 18:41, 11 January 2025 (UTC)

:It’s also common to adress oxygen with red and that’s what stood out to me first Geefkip (talk) 18:42, 11 January 2025 (UTC)

The figure and description is correct. There are 4 oxygen atoms bonded to each silicon - although as this is a pseudo 2D representation only 3 are visible. Polyamorph (talk) 20:04, 11 January 2025 (UTC)

Remove "Glass is sustainable" greenwashing

"Glass packaging is sustainable, readily recycled, reusable and refillable."

I have doubts about sustainability of glass packaging, especially since this claim comes from FEVE ("FEVE is the Federation of European manufacturers of glass containers for food and beverage and flacons for perfumery, cosmetics and pharmacy markets.") so I assume they are biased.

Glass has a high melting point and glass recycling is an energy intensive process. Especially single-use glass, which is still found a lot for example in beer bottles, is not sustainable. In practice, even glass containers that can theoretically be reused are not commonly reused and instead discarded into recycling, even in deposit systems in Europe. For example in Romania, a deposit on glass containers was introduced but the machines at the supermarket crush the bottles.

We are facing an ecological catastrophe and I think calling glass sustainable without putting data next to it is misleading at best. 212.95.5.63 (talk) 14:13, 20 March 2025 (UTC)

:For a better source than FEVE, see the BBC's article instead: https://www.bbc.co.uk/bitesize/articles/zc46m39#zhssn9q
