Talk:Lost-wax casting

message: In it's current form, this article has a strong lean towards bronze-casting.  While it is certainly a major use of the technique, it is far from the only one.  I'd like to remove the sections that imply that bronze-specific steps, such as applying a patina fall within the relm of "Lost-wax casting".  There is already an article on Bronze sculpture, and such topics are appropriately covered there. -Verdatum (talk) 17:00, 18 November 2008 (UTC)
replies: text: I think you're right Verdatum, it is indeed far from the only one, but why not add just a small chapter or footnote covering bronze casting, with a direct to other articles? By discussing it in a separate chapter, it's immediately clear that bronze isn't the only metal or even material cast in this way. I was the one who put it back in, but perhaps it can be shortened drastically, because Patina covers that technique. If I were looking for more information on lost-wax bronze casting and landed up here, I certainly would value the information, and if I were only looking for the process as such, I wouldn't mind this information, as long as it was clear that bronze is just a sub-chapter. I know, I'm probably a bit prejudiced, as a sculptor, but that's how I see it. By the way, I am not too happy with the latest addition of a largely unreadable portion on casting history. It look like a monograph on casting history, not like encyclopedic material. I'm glad it's being improved, but I think there are still too many quotes and weasel words. This portion is also largely bronze-centered. Then again, I think with improvements going on, it could clean up nicely. Lots of references though, I respect the work. Anyway, thanks for the valuable contributions here, cordially,--Satrughna02 (talk) 22:45, 18 November 2008 (UTC)
replies: text: I shortened the patination part a little. Hope you can agree, if not, please change it as you wish. Please don't get me wrong, I think you've done great work on this page- I noticed that you've already changed the things I complained about above; apologies. Best wishes, --Satrughna02 (talk) 16:02, 19 November 2008 (UTC)
replies: text: To be sure, I find patina really really interesting, but it just isn't at all part of the lost-wax casting process.  It's off-topic here.  It belongs in [Bronze sculpture#Finishing]] and patina.  I do think the finishing section of bronze sculpture can be expanded into more of a WP:SUMMARY style. -Verdatum (talk) 18:46, 20 November 2008 (UTC)
replies: text: I get the point, you're absolutely right. I throw in the towel; but as I have little experience with the summary style, is it OK with you if I just watch how you do it? ;-) If I see possibilities for improvement, I'll get back to you here. I'll keep watchng the changes though, interesting stuff. Greetings, --Satrughna02 (talk) 22:19, 20 November 2008 (UTC)
thread_title: Bronze-centric

message: I wish to condense the notes and references sections together by changing to named references.  I don't find any of this content to be terribly controversial, so citing the page number for every fact is a bit overkill.  This should make it easier to see the frequency of use of each source, and reduce redundant content.  I just want to give notice before doing the work in case anyone has a problem with this. -Verdatum (talk) 19:11, 7 January 2009 (UTC)
replies: text: Hear hear! Good idea, waaay too much references anyway. --Satrughna (talk) 19:54, 7 January 2009 (UTC)
replies: text: Yes, good idea. PRRfan (talk) 21:41, 8 January 2009 (UTC)

text: Alright, I did a bunch of changes, so here is the diff for posterity.  I removed all the page number citations.  I could add them back into a page range (eg "pp. 1, 6, 9-24"), but I sort of got lazy.  I removed the footnote messages.  Usually transforming them to statements in parenthesis.  I left the references that weren't cited anywhere, though they can potentially be deleted.  I started trying to convert the references into using template:cite book, but that got boring really fast, especially when I couldn't figure out the meaning of some of them. -Verdatum (talk) 19:49, 9 January 2009 (UTC)
replies: text: Wow. Well done. PRRfan (talk) 08:04, 10 January 2009 (UTC)

text: Looks OK to me, but why are there so many books missing from the ref list? For Instance Agrawal, which has been cited in the first lines, isn't mentioned in the reference list. Am I missing a point here? Greetings, --Satrughna (talk) 21:10, 9 January 2009 (UTC)
replies: text: Oh right, that's just a naming convention.  The footnotes section is really the references section, and the references section would either be further additions to the same section, or in an "Additional works" section. I'll fix that now. -Verdatum (talk) 21:48, 9 January 2009 (UTC)

text: Oh, Now I see, Apparently there was an edit flaw with the Agrawal causing it to not show up as the proper reference.  I didn't remove any of the reference descriptions anywhere intentionally, so if anything else looks amiss, it shouldn't be anything too hard to fix. -Verdatum (talk) 21:55, 9 January 2009 (UTC)
replies: text: Good work Verdatum, but what happened to refencerences 8a-b-c-d about Pliny? The article is shaping up fine now, much better this way. Greetings, --Satrughna (talk) 16:03, 10 January 2009 (UTC)
replies: text: Arrg!  Fixed now, thanks! -Verdatum (talk) 17:38, 13 January 2009 (UTC)
thread_title:  Notes condensation 

message: The photo with the plaster model looks wrong.   Why plaster needed?  Should be direct to wax and the clay coat.  —Preceding unsigned comment added by 69.149.15.194 (talk) 11:48, 13 March 2010 (UTC)
replies: text: You're right, no plaster is needed. What's needed is a hollow wax cast, which is cast from this here same rubber mold. Then on to the fireproof mold with sprucing. Unfortunately the photo came only with the plaster cast, instead of the hollow wax cast. But just read the text....--Satrughna (talk) 13:24, 3 August 2010 (UTC)
replies: text: For someone trying to understand the process, the rubber mold with the plaster cast is misleading. For the unfamiliar (like myself), since the page is about a casting technique that destroys the mold, why show an intact two-piece mold prominently in the photos?  —Preceding unsigned comment added by 173.14.15.225 (talk) 00:46, 6 October 2010 (UTC)
replies: text: Rubber molds are usually not destroyed in the process. If someone would, he would soon be fired himself ;). If you read carefully, you can see the model in wax is made first, then a rubber mold, from which comes the hollow wax cast. This cast is then covered with a casting mold, which is not to be confused with the previous rubber mold. Those last two are eventually destroyed in the process. Hope that clears the doubts?--Satrughna (talk) 16:13, 21 October 2010 (UTC)
thread_title:  photo 

message: Someone just changed a "mould" to "mold". The article uses both words. Can we agree on a dialect for this article?
This article started out as a redirect, but then PJacobi copies some material in from another article, Lost wax casting process, in 2006. (It looks like it was a rename.) His edit used British English, so I believe the policy is this article should be British English (unless Lost wax casting process was originally AE or there was a some other agreement).
Can we mark this article as BE? Glrx (talk) 17:57, 28 February 2012 (UTC)
thread_title:  Variety of English 

message: I can see no good reason for the current redirect of Bronze casting to this Lost-wax casting article. Bronze is often cast using the lost-wax process; large and small bronze statuary, tools, medallions etc., have been and still are very often sandcast. Haploidavey (talk) 14:38, 2 March 2016 (UTC)
replies: text: Agreed - but where should it go? Casting (metalworking) is super industrial/technical. If bronze sculpture were better, it could go there. Johnbod (talk) 16:57, 2 March 2016 (UTC)
replies: text: Difficult. Each likely has a different readership, seeking essentially similar information in quite different context. The Sand casting article is also very technical, being mostly concerned with modern industrial technique. Strikes me that some terms and techniques used in bronze sculpture (eg "sprung" patches and so-called "Roman joints") are quite alien to modern industrial production but have been used in many traditional art foundries from ancient times into the modern era - and still are by bronze restorers. I'll think some more on it. Haploidavey (talk) 17:52, 2 March 2016 (UTC)
thread_title:  Sand casting 

message: The oldest known examples of this technique are the objects discovered in the Cave of the Treasure (Nahal Mishmar) hoard in southern Israel, and which belong to the Chalcolithic period (4500–3500 BC). Conservative Carbon 14 estimates date the items to c. 3700 BC, making them more than 5700 years old.
This article contains a properly sourced statement of an amulet that is 6000 years old and is claimed to be the oldest. Update needed? Bataaf van Oranje (Prinsgezinde) (talk) 09:54, 4 December 2016 (UTC)
replies: text: Yes, but it'll be enough to simply place these claims in sequence. Neither technique is infallible, neither object has been dated using both techniques, and one can expect margins of error in each case. The claimed age of each is what matters. Two bald, cited statements of estimated age will be enough, and we don't need to say which is "oldest" (it's not a competition, after all; and the estimated dates speak for themselves).
