message: There is a broken link in the article, can someone redirect it to its proper location? I have not had time to figure out how to do this, or even know if the article exists.
:Since there is no reference as to which of the various links is your broken link, I will mention one I found.

message: Does anyone understand what "This map is consistent with incomplete set of data too as long as the top producer is known" actually means? It does not make a great deal of sense to me. Also data should not be published if it is incomplete.  —Preceding unsigned comment added by 81.157.127.176 (talk) 21:50, 23 September 2007 (UTC)

I can see how the image I put on there may be considered spammy and a couple of references unreliable and I have therefore removed them, but I refuse to remove the mention of medical benefits with the reference to about.com. On there website, they link to the follwing research:

replies: text: Removed again. About.com is "not" a reliable source. Also the re-added link-bits to the sodium and calcium bentonite sections were pure spam (sales page of an alt. med. retail supplier). A note regarding health and/or medicinal uses would be appropriate if properly sourced. Also, note the current references were used in support of the article - they are not ext. links, rather references predating the current ref tag system. Vsmith (talk) 22:56, 23 December 2007 (UTC)
replies: text: those citations don't appear to come just from about.com, for instance santurio et al is at . bentonite is used for broadly medical reasons, no doubt, and the article can include that usage without making any claims as to its efficacy. a source from the uk's national cancer institute: . (this now seems to redirect to some outsourced site, and its relationship with the national cancer institute is not clear. Mongreilf-4/4/09) its use in "colon cleansing" or acne treatments again can be noted without any claims as to its efficacy, a source only needs to say it is used and this use is widespread enough to be notable. a note regarding any known lack of efficacy, properly sourced, could also be added. i'll come back in a few days and if nothing is written here i'll edit the article accordingly--Mongreilf (talk) 13:52, 4 January 2008 (UTC)
thread_title:  Medicinal uses 

message: Hey all, sorry I am not making this edit directly on the article...though a long-time wiki reader, I haven't really messed around editing articles yet. Maybe I'm scared to. I will someday, someday soon, but in the meanwhile, I present this information in case anyone finds it useful or wants to incorporate in the bentonite article.
My problem is with this sentence:
"The absorbent clay was given the name bentonite by an American geologist sometime after its discovery in about 1890 — after the Benton Formation (a geological stratum, at one time Fort Benton) in Montana's Rock Creek area."
I'm living in Montana right now and researching a film about bentonite, so I wanted to locate "The Benton Formation." However, this sentence was unsourced, and when I contacted a historian in Fort Benton, MT, he had no knowledge of a "Benton Formation" in MT (though he knew of one in Colorado and one in Iowa). My research did turn up this source, however, the State of Wyoming Geologic Survey <http://www.wsgs.uwyo.edu/industrial/bentonite.aspx>, which states:
"Bentonite, originally known as ‘mineral soap’ or ‘soap clay’, was named ‘bentonite’ in 1898 by Wilbur C. Knight for deposits in the Benton Shale near Rock River, Wyoming" (which, to be clear, is nowhere near the Montana border).
I'm not even sure Fort Benton is/was in Montana's Rock Creek area, but in any case, since I can actually cite my source, WY Geologic Survey's info should probably replace the problematic, uncited info currently there. Sorry this talk entry is so rambling. Hey, it's my first. This is why I'm not editing the real article. Thanks for your patience. I'll hone my posting skills in time. At least I'm practicing on a fairly quiet talk page...

thread_title:  The name 'bentonite' 

message: I think I'll take advice of Vsmith, and create a separate page on healing/medicinal clays. I've been researching this subject, and there's quite a lot of material to put in there. Documented use of such clays for healing goes back to ancient times. Just about every health spa uses such clays, so a separate page is needed to reflect various uses. Clearly, there are some problems with nomenclature, that can be clarified somewhat.
After a new page is up and running, then perhaps some of the material referring specifically to bentonite clays can be copied back to bentonite page. I'll do it in the next few days.

replies: text: Good plan as there is likely sufficient verifiable info to work from. Please avoid commercial sources and hype - stay with reliable sources. You might want to look at Geophagy as a related topic. Vsmith (talk) 19:43, 4 April 2009 (UTC)
thread_title:  new page on healing/medicinal clays 

message: I would like to ask Vsmith and others about whether it is valid to use "drugs.com" site as a valid ref. Because my info and ref was deleted based on using "drugs.com".
Well, I've done a search, and it looks like this is quite a popular site at Wikipedia...
http://www.google.com/search?hl=en&q=site%3Aen.wikipedia.org+%22drugs.com%22&btnG=Search
According to Google, this site is now used 292 times at Wikipedia! So is it valid or not? Dyuku (talk) 15:44, 6 April 2009 (UTC)
replies: text: Hmm... Anyway, your ref simply stated something about using bentonite magma to increase the viscosity of Calamine lotion. This so-called bentonite magma is simply a suspending agent (see ). Vsmith (talk) 03:33, 7 April 2009 (UTC)
thread_title:  question about "drugs.com" as valid ref 

message: In the field of chemistry concerned with greases and lubricants, some forms of grease are described as using "bentone clay" as a thickening or gelling agent.  Is this the same material as "bentonite?"  —Preceding unsigned comment added by 69.41.40.21 (talk) 18:28, 3 October 2010 (UTC)
replies: text: Industrial and pharmaceutical products that start with bento- contain bentonite clay, but other substances as well. Bentone clay is most likely a clay based on bentonite, but with additions. Rumiton (talk) 15:23, 28 October 2010 (UTC)

thread_title:  External links modified 

message: Bentonite is NOT a phyllosilicate. It is a rock COMPOSED OF MINERALS BELONGING TO A CLASS OF PHYLLOSILIACTES. This is a major difference. Eudialytos (talk) 18:25, 21 October 2017 (UTC)
thread_title:  Wrong category 

message: Several Internet sites of questionable credibility reference bentonite mining as an extremely-damaging practice and warn away from clumping cat litter because of this. Something should be added about the mining of bentonite, its industry value, and its environmental impacts—be they notably high or low. Bentonite is a notable input in many industries, and so the GDP value and environmental considerations are notable whatever their magnitude. John Moser (talk) 21:59, 25 September 2019 (UTC)
