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?[edit]

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? (talk) 21:45, 16 November 2010 (UTC)

Bolognese stone[edit]

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[edit]

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 (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?[edit]

Found this weird anomaly . Undetectable Firearms: 18 U.S.C. § 922(p). "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?[edit]

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. (talk) 15:41, 18 January 2014 (UTC)
