Talk:Drying oil

Comments

Okay...I just started working on a posting about the chemistry of oil paint which includes a brief (about 3/4 page) discussion of drying oils. Now I'm worried that I should have put this information on the "Drying Oil" page instead. Or should I just provide a link from "Drying Oil" to my article in progress? BTW as of today the article I'm working on isn't picked up by the search engine yet...it should be up in a few days. The title is "Chemistry of Oil Paint" (very imaginative!)Medora 13:54, 5 July 2006 (UTC)

Hi - I "beefed up" the drying oil article with the info from your article. Steve 14:19, 5 July 2006 (UTC)

Drying oils

--118.95.12.161 (talk) 13:40, 21 January 2010 (UTC)''When certain oils are exposed to air ,they form a hard transparent resinous mass.These oils are called drying oils.

Temperatures and drying rates

Under what conditions can/do other oils polymerize? For example, will some other type of oil dry, but only when baked at 200F, for example? Is there any on the rate of reaction? This would be particularly helpful in modifying/perfecting painting and cooking techniques, and so far I have not been able to find any good spec sheets online. Can anyone help?

You might check Linseed oil for some info since it seems to be the main drying oil. In general, Wikipedia is not in the advice or how-to-do-it business, per our directive WP:NOTMANUAL.--Smokefoot (talk) 02:07, 10 February 2013 (UTC)

Is castor oil a drying oil or not?

This article lists Castor Oil as a drying oil while the article on castor oil specifically mentions it is not a drying oil. There is a contradiction between those two articles. 2607:FA49:CC20:8C00:C9F5:2434:A6DF:5C8 (talk) 11:25, 3 May 2025 (UTC)

Just noticed this, too. I'm not qualified to say which is right. 172.88.78.186 (talk) 18:17, 10 September 2025 (UTC)

It's not a drying oil. There is some variation here for whether 'an oil' has been treated to make it a more drying oil (the difference between linseed oil and boiled linseed oil), so some change their nature depending on how they're prepared. But the crucial definition would come down to the oil's iodine number as the standard test for this, and castor is non-drying. Andy Dingley (talk) 18:57, 10 September 2025 (UTC)

Role of metal catalysts

Hi Smokefoot (talk · contribs), I have brought the conversation here as it's about the article content and references. Because of the summary I had wrongly presumed you may of taken the reference out by mistake, so apologies if that wasn't the case. The content had been tagged prior to my edit as needing a citation. From your message I believe you removed the ref because you feel it is not relevant to the drying process. The article copy specifically discussed methylethyl ketone oxime stopping skinning in paints. The source I added states methylethyl ketone oxime prevents peeling in paints and is an antiskinning agent, so I felt it was suitable. If you don't agree is there something you think would be a more suitable reference for this copy or do you think that the copy should be taken out? It would be good to find consensus here, as I've noticed you've removed the ref again but I don't believe information that is not verifiable should stay in the article.

@LateFatherKarma: No problem. The ChemEng source you cite, which seems pretty specialized (see WP:SECONDARY) describes a process for making MEKO. What is called for is a source for the phenomena of skinning or antiskinning. There are more suitable sources for those phenomena than the chemE prep. Another thing is that we (me esp) are skeptical of primary citations. In any case, thanks for the note and happy editiging. It's not a big deal. I'm trying to make a point for someone who might be unfamiliar with Wiki-chem culture. --Smokefoot (talk) 14:41, 25 April 2026 (UTC)

The article content doesn't discuss the phenomena of skinning/anti-skinning in any depth at all, so I am struggling to see why what you've suggested would be better. It discusses that MEKO is an anti-skinning agent. The ref entirely supports this claim and does so in the introduction (citing other references to relevant research). I would deem that not to be a primary source. I propose it is reinstated or the unverified copy is removed. LateFatherKarma (talk) 15:11, 25 April 2026 (UTC)

I have taken out the unsourced content. LateFatherKarma (talk) 15:39, 26 April 2026 (UTC)

Feel free to discuss any aspect of this article. We are both aiming for the same thing - a quality description of a fairly complicated process.--Smokefoot (talk) 16:12, 26 April 2026 (UTC)

Absolutely. I've reverted your last edit due to the error it introduced to the reference list. Also resolved the spacing/punctuation problems that were introduced after your edits yesterday.LateFatherKarma (talk) 17:02, 26 April 2026 (UTC)
