Sourcing for origins with Jewish glassblowers

The statements about techniques developed by Jewish glassblowers in Judea and Alexandria echo things I've seen elsewhere, but in this article they are unsourced or sourced to references that don't support the statements. If anyone knows of documentation, I would love to learn more about this! Bassomatic (talk) 19:29, 28 December 2010 (UTC)

I'm also interested in this. Have you seen this, though it mostly concentrates on "Jewish glass" rather than Jewish glassworkers, and indeed glass distributors and traders, who also seem to have been important. Johnbod (talk) 16:34, 10 February 2011 (UTC)

Clear window glass in Herculaneum and Pompeii

Everyone knows Vesuvius covered these cities in 79AD. Yet the sentence before that dates the invention of clear glass was in 100AD. Both cannot be true. Underfly (talk) 10:57, 25 August 2015 (UTC)

Poorly referenced U.S. section

The section on American glass is largely unreferenced, and much appears to have been copied from poorly written sources. Red58bill (talk) 05:51, 30 December 2010 (UTC)

And in what way is the whole section historically important, or was it all just written by a yank.— Preceding unsigned comment added by [[User:{{{1}}}|{{{1}}}]] ([[User talk:{{{1}}}#top|talk]] • [[Special:Contributions/{{{1}}}|contribs]])

Date of first glass

In the first paragraph of the History of glass article the first man made glass is dated as 3500BC. Two lines later (and further down the page) it is dated at the middle of the 3rd millenium BC, which is 1000 years later. Which is right? David jd Johnson (talk) 14:06, 23 August 2014 (UTC)

Hello fellow Wikipedians,

I have just added archive links to one external link on History of glass. Please take a moment to review my edit.

Alternatively, you can add {{nobots|deny=InternetArchiveBot}} to keep me off the page altogether, but should be used as a last resort. I made the following changes:

Hartley's involvement

I have removed a sentence that is ambiguous: "The requisite technology for the construction of plate-glass had been made possible just a few years earlier by James Hartley, working for the firm Chance Brothers." In fact, Hartley was a crown glass maker and did not necessarily approve of the 'new' sheet glass manufacture that was introduced by Chance Brothers in 1832, by using French workers. Plate glass was made by casting glass onto a table and then rolling it flat. The name of the firm of 'Chance Brothers' was also not used until 1836, after Hartley's sons left 'Chances & Hartleys', but was called British Crown Glass Company until 1834. I hope this clears things up. — Preceding unsigned comment added by GlassyEye (talk • contribs) 10:49, 14 March 2017 (UTC)

Application of Glass

Hello,

This page does a broad section on the history of glass and manages to touch on what different countries and cultures did with the glass that they developed. I believe an independent section on applications of glass should be added. This could delve into why a culture developed a specific type of glass, what they used it for, and how it lead to the development of "better glass" or other applications in other countries or cultures.

'Iran' section has atrocious grammar

Here's an extract: "Today it is certain that the mosaic glass cups from the Iron Age of North Iran, such as Hassnlou Tepe, Marlik Tepe." uh what? Could someone who's more knowledgeable with Wikipedia (& ancient glass from Iran) tidy this up? 132.181.92.156 (talk) 20:13, 16 January 2019 (UTC)

Looks like that was from a set of recent edits by an IP editor a few weeks back: [1]. Feel free to tidy it up. TJRC (talk) 20:38, 16 January 2019 (UTC)

Glass or faience?

the beginning of the articla states that there is a controversy about the place where glass was first made: it is thought to have been discovered in Mesopotamia, though it may be Egypt or Syria... it also states that it might have been a byproduct of metalworking or faience making... I have a problem, since true faience seems to be a VIII century AD discovery, and the material known as Egyptian faience is actually a vitreous product... maybe some clearing up is needed? --Svartalf (talk) 15:55, 29 November 2019 (UTC)

Chronology of Roman glass

With the discovery of clear glass (through the introduction of manganese dioxide), by glass blowers in Alexandria circa 100 AD, the Romans began to use glass for architectural purposes. Cast glass windows, albeit with poor optical qualities, began to appear in the most important buildings in Rome and the most luxurious villas of Herculaneum and Pompeii.

This doesn't make sense chronologically: Herculaneum and Pompeii were destroyed in 79 CE, so they can't have glass windows produced using techniques invented in 100 CE. Daask (talk) 17:02, 3 September 2021 (UTC)

No, I expect it should be "during the 1st century AD" - see the Roman section below. Johnbod (talk) 20:02, 3 September 2021 (UTC)

See also Roman_glass#Tesserae_and_window_glass which says by the beginning of the 1st century (probably) - I'd change to that if the ref had a page #. Johnbod (talk) 20:13, 3 September 2021 (UTC)

Date error

Reference 1: origin at least 3600 years ago Reference 2: oldest objects date to mid third millennium BC Conclusion: oldest objects, (2500 BC) are therefore 4500 years old, predating reference #1 by nearly 1,000 years. 5,000 years is a conservative and citable estimate. Reference #1, though technically not incorrect, is incongruent with reference #2. A mathematical error. 50.34.136.184 (talk) 12:34, 26 December 2021 (UTC)

Agricola misattribution

The origins section attributes an origin story of glass to Agricola. Looking at the source material(*), it seems that this is more likely a note from the English translators, and not part of the original work. The quote itself seems to be a direct translation of Pliny the Elder XXXVI. 65. Not sure what to do here, since the quote appears correct, but it looks like it's Pliny via the English translators.
