Talk:Lead glass

message: We could do with some more information on lead safety, including some links. —Ben FrantzDale 20:30, 5 June 2006 (UTC)
thread_title: Safety

message: I think that lead crystal should be merged as a section in the lead glass article, as lead crystal is a lead glass. The interwikis are not decisive because they are divided between two articles which are of the same subject. Please note that similar suggestion was discussed and agreed, but the vote took place at 2006. Fuzzy (talk) 12:41, 14 December 2008 (UTC)

thread_title:  Merging "[[Lead crystal]]" into "[[Lead glass]]" 

message: Currently the article states that lead glass "contains a minimum of 24% lead oxide" but fails to specify if it's weight/weight, weight/volume or volume/volume. Any ideas? Kinemaτ 11:43, 2 October 2009 (UTC)

message: "When lead-glass beverage containers are used in the ordinary usual way they do not pose a health risk."
What is this supposed to mean? What is the " ordinary usual way"?  — Preceding unsigned comment added by 173.180.54.97 (talk) 02:47, 20 June 2011 (UTC)
thread_title:  The ordinary usual way 

message: I'm interested in the university study that's cited in the Safety category - is it original research? I can't find it on Google Scholar or the North Carolina State University website. No thesis paper, no obscure journal article, no mention in a CV - only stuff Google turns up are copy & pastes of the Wikipedia article. Anyone know where to find this study or at least a mention of it? Medial Plexus (talk) 11:18, 3 September 2012 (UTC)

message: There is a tableware product called "fine glassware". This typically refers to certain types of water glasses or wine glasses.
I am unable to find sources describing what this is, but it is sometimes called crystal. Is "fine glassware" lead glass? Does anyone have a source for this?  Blue Rasberry (talk) 19:24, 17 March 2017 (UTC)

message: Many of the items in the manufacturers’ table contain the text ‘production continued’. What does this mean? Is it supposed to mean that the manufacturer is extant? If so can it be changed to something like ‘currently producing’ or ‘in production’ with a year when it was most recently confirmed that the company was manufacturing?

message: When tapped, lead crystal makes a ringing sound, unlike ordinary glasses. Consumers still rely on this property to distinguish it from cheaper glasses. Since the potassium ions are bound more tightly in a lead-silica matrix than in a soda–lime glass, the former absorbs more energy when struck[dubious. This causes the lead crystal to oscillate, thereby producing its characteristic sound.  
Since lead is four coordinate bonded in glass, where sodium and potassium are one, lead contributes more to sound conduction, so I am not surprised that it makes a better ring.  That is, or course, not a WP:RS, and I didn't even do any WP:OR. Gah4 (talk) 01:44, 7 January 2021 (UTC)
replies: text: If the leaded glass absorbed more energy, it would ring less than ordinary glass! So the sentence about absorbing more energy is definely incorrect. 68.60.174.26 (talk) 17:58, 11 April 2022 (UTC)
replies: text: It seems to me those statements in wikipedia are folktale, although it may have been true in a distant past. The statements are a mixed bag. "When tapped, lead crystal makes a ringing sound, unlike ordinary glasses" is unsourced and not well defined; it is found mainly on commercial websites. "Consumers still rely on this property to distinguish it from cheaper glasses" is a cynical statement about the gullibility of people, as consumers typically do not verify such statements, especially when it is not easy to determine if something is lead glass. The consumer would have to submerge the glass in water, determine its density, and decide if it is 2.8 g/cm3 (lead glass) or 2.4 g/cm3 (ordinary glass). "... This causes the lead crystal to oscillate, thereby producing its characteristic sound" is nonsense. The cause for oscillation is that glasses have mass and elasticity, but this is valid for ordinary glass too. Today, lead-free glasses produce a nice ringing sound too.

replies: text: It could possibly have nothing to do with the type of glass, and instead be a result of the shape, size, and thickness of particular pieces – i.e. if the lead glass as manufactured was [thicker, thinner, more symmetrical, whatever] compared to ordinary glass.
