Talk:Kaolinite

From Wikipedia, the free encyclopedia

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)

Hi - I'm not sure if your comments would added to what already exists. What you describe is porcelain, and this already has a article in Wikipedia. Also though factories around Limoges did, and still do, produce porcelain they were not "responsible for starting a craze for fine China." Also providing a suitable glaze is used, and properly fired, crazing is not a problem on soft paste porcelain. (both hard and soft porcelain are still made in Limoges) —Preceding unsigned comment added by 86.147.253.110 (talk) 19:50, 17 February 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)

Still consider it an adv. - moved link to External links section. Re-instated my other edits that you also reverted. Tried to improve the article flow. I don't really see the commercial info as that important. It is NOT an insecticide. I leave it to you to find unbiased data to support this commercial link. I will delete it in the future if no noncommercial links are provided. It is not Wiki policy to promote commercial products. -Vsmith 03:21, 28 Oct 2004 (UTC)

[edit] Discovery?

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

[edit] Chemical formula

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)

Fixed. Disagreement in references, Deer says 4:4:10:6 all the others including my Dana say the other. So, went with Dana and online refs for consistency. Vsmith 13:48, 11 June 2006 (UTC)

[edit] noodle?

"semi-dry noodle" ??? --Gbleem 13:15, 17 April 2007 (UTC)

Why??? Theriac 15:19, 17 April 2007 (UTC)

Why what? --Gbleem 21:20, 17 April 2007 (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)

[edit] Images

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)

I have answered here. Best regards Rhanyeia 12:31, 16 August 2007 (UTC)

[edit] Hydrocephalus research (Bering, 1962)

"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.

[edit] Removed reference and proper formatting

Kaolin is also used experimentally in animal models of hydrocephalus research (Bering, 1962).
