Talk:Barium sulfate

Merge?
Shouldn't this perhaps be merged with Barite? --Pinnerup 05:42, 31 October 2006 (UTC)
 * A good way to handle this common problem is to strip barite of most of its non-mineral content and insert the phrase . This way the readers get focused reports, and we minimize duplication of effort.  Not that I have any special power or insight.--Smokefoot 10:16, 31 October 2006 (UTC)

Anacoustic foam?
I'm not sure if this exists, or if so what it is. I can only find reference to acoustic foam, not anacoustic foam. Is this a typographical error? 86.16.21.237 (talk) 21:45, 16 November 2010 (UTC)

Bolognese stone
I read about bolognese stone which is supposed to be barium sulfate. when calcined it turns phosphorescent but i have no real references. Benkeboy 14:43, 2 October 2007 (UTC)

I will have to write about this! --Stone (talk) 14:55, 12 June 2012 (UTC)

Not same as barium hydroxide
I don't think BaSO4 is the same as baryta as stated. Baryta says it's barium hydroxide. I don't know. User:altaphon — Preceding unsigned comment added by 71.135.109.73 (talk) 02:56, 8 November 2012 (UTC)
 * Sorry, but that's incorrect. It didn't make sense to me because the sulfate is extremely insoluble in water, while the hydroxide is soluble.  I verified that conclusion with some readings in photographic technical books.  Read the reference I cited. I will-revert the deletion.  --Zeamays (talk) 21:24, 8 November 2012 (UTC)
 * I have also edited the redirect that caused the confusion. The reference is:  Salvaggio, Nanette L. Basic Photographic Materials and Processes. Taylor & Francis US, Oct 27, 2008. p. 362. --Zeamays (talk) 21:35, 8 November 2012 (UTC)

Undetectable firearms?
Found this weird anomaly. Undetectable Firearms:. "Barium sulfate or other compounds may be used in the fabrication of the component. " Any chemist/historian care to explain why this chemical compound is singled out and not others? It definitely would be worth adding to this Barium sulfate article if there's a decent back story as to how this wording appeared in the Undetectable Firearms Act.

Used in ceramics?
I looked up this article because I read in a book on Wedgwood pottery that Barium Sulphate was a major ingredient in Josiah Wedgwood's famous Jasper Ware, and I wondered what it was and where Wedgwood obtained it. I don't know if the substance is still used in ceramics, but if it is maybe some more knowledgeable person could add something.109.149.31.4 (talk) 15:41, 18 January 2014 (UTC)

Image same as BaN3
Hi, the image here looks like it is exactly the same as the image for BaN3 on the barium azide page. I'm not sure if the image is showing BaSO4 or BaN3, but it seems that one of the images is incorrect and needs to be removed/replaced. Sticklink (talk) 13:10, 10 January 2023 (UTC)


 * It looks like the barium azide image was copied from the one on this page. I’m theoretically not opposed to using the same image as an illustration (under very specific circumstances), but that copy cannot exist with its current author claiming to own it. I suggest nominating that file for deletion on commons, and we can go from there. — HTGS (talk) 12:44, 14 January 2023 (UTC)
