Kaolin, along with Feldspar and Quartz, make up the 'clay' that was (and is) used in making fine china. The LIMOGES region of France (250 miles SW of Paris in the Vienne Valley) was responsible for starting a craze for fine China in the latter half of the 19th century. The composition makes a hard paste that when fired at high temperatures produces a beautiful translucent porcelain. This means there is no crazing as there is with soft paste porcelain. A piece manufactured in 1860 looks just the same in 2008 if cared for properly. I can provide more info if anyone wantsGotchakatya (talk) 21:32, 20 January 2008 (UTC)
Vsmith stated that he/she removed a commercial adv. However, the removal also removed some important information about an environmentally friendly pesticide that has become available. I placed that information on there originally; the information is valid and should not be removed. At the time of placement, the link was the only source I could find that offered further information. If you can find a non-commercial link that offers significant further information, please be my guest. I don't have time to go looking. But do not remove valuable information and information sources without finding better. Pollinator 22:30, Oct 27, 2004 (UTC)
The name of the Chinese town is Kao-Ling (or Gaoling, "high ridge"), located in the Jiangxi Province of southeast China. —Preceding unsigned comment added by MinMad (talk • contribs) 08:12, 1 August 2008 (UTC)
How is kaolin supposedly discovered in 1867 when it's been mined there for over a thousand years?
Good point ... it's been mined around the world long before 1867, and in the case of Cornwall in the UK since 1746. Perhaps the original author could elaborate Regards, Andy
I was tempted to put ((contradict)) on this article, but the contradiction was rather minor. Anyway, it says at the top of the article that Kaolinite is Al2Si2O5(OH)4, but in the info box it says Al4[Si4O10](OH)6. Which is it? ~ Oni Lukos ct 12:50, 11 June 2006 (UTC)

Hi Gbleem. Apologies for being flippant earlier, I was just responding in a similar fashion to your original comment. I was wondering why you highlighted semi-dry noodle. ThanxTheriac 22:33, 17 April 2007 (UTC)

Please can someone give an idea of size, such as a scale bar. This is very basic stuff. Not including these is bad practice and makes the images of very little value. —Preceding unsigned comment added by 81.153.64.39 (talk • contribs)
"Kaolin is also used experimentally in animal models of hydrocephalus research (Bering, 1962).[5]"
This obscure sentence is very unclear and the use of kaolin in this study is not obvious. Is a kaolinite paste used to reproduce the shape of a skull to determine some biometric parameters ? This is very specialized and likely not relevant to an encyclopedia article. Moreover, in the link to Hydrocephalus research I could not see any reference to kaolin. As a consequence, I would suggest to develop, or better to remove this sentence and to store it on the discussion page along with the corresponding reference.

http://en.wikipedia.org/wiki/Halloysite looks the same as Kaolin. Should those two be merged? Yurivict (talk) 08:25, 5 June 2009 (UTC)
The article currently states: "Kaolin is known in traditional Chinese medicine by the name chìshízhī (赤石脂), literally 'crimson stone resin'."
Howevver, it seems that chìshízhī (赤石脂) usually refers to Halloysite specifically and not Kaolinite (look at the colour in these pictures). Please comment and/or edit the article appropriately if you have further insight. — AjaxSmack 01:57, 5 March 2010 (UTC)

Exactly what is Kaolin? I find that it seems to be the main component in the sealant/gasket material I might use. It may be buried in the article somewhere, but I didn't see it. Probably a good idea to make the distinction near the top of the article. CountMacula (talk) 04:34, 5 August 2011 (UTC)
I can't think of other concepts that would cover something with long-range order but are not strictly crystalline. elle vécut heureuse à jamais (be free) 21:50, 11 October 2011 (UTC)
The current text reads:
I'm pretty sure that "a defect ... spinel" isn't quite right. Defect-ridden? DeFacto? Synthetic? I can't figure out what they meant.

Hello fellow Wikipedians,
I have just added archive links to 2 external links on Kaolinite. Please take a moment to review my edit. If necessary, add ((cbignore))
after the link to keep me from modifying it. Alternatively, you can add ((nobots|deny=InternetArchiveBot))
to keep me off the page altogether. I made the following changes:

Kaolinite Al2Si2O5(OH)4 actually is AlOOH.SiO2 aq. it forms plagioclase and orthoclase with Na, K and Ca. less known Mg, Fe, etc. Those are Salts of Kaolinite.
An acid does not have to be water soluble.
It can be written as HAlSiO4
in other words Alumosilic acide.
name occurs on Mg pharmatologic compounds.
Consequences: Ammoniumkaolinite exists. What is that? if Ammoniumkaolinite exists is Kaolinite soluble in Ammonia?
salts of kaolinite are as to say the Siliciumoxide ""hydrates"" of aluminates. (where SiO2 refers to silic acide)
can Acidic properties of Kaolinit be proven, such as reaction heat with I,II?
Where also Mullite behaves like that and hydrogenBentonite/Kyanite. the hydrogenBentonite would need a chemical name on alumosilic acides. (also have ammonia salts/minerals?)

Hello all - I'm new to creating tables for Wikipedia, indeed new to Wikipedia as a whole. I've just created and added a table summarising production output by country. As the data is presented as a single column it is rather long. It would be preferable if the data was presented in multiple columns. Is this possible? Does anyone know how to do it? If so please would they advise in a way that a necomer to Wikipedia can understand. Thank you in advance.User name for this site (talk) 13:40, 19 February 2023 (UTC)

In the article on halloysite it states that the output of the halloysite mine at Matauri BayinNew Zealand is 20 thousand tonnes PA, which appears to be in conflict with the 11 thousand tonnes attributed to NZ in the list of outputs.
