Could someone clear up weather or not resin and Sap (plant) are the same? Our article on sap seems a little confused. Savatar 04:37, 26 May 2006 (UTC)

"This article is about the chemical secretion and not the resin from smoking weed. For other uses, see Resin (disambiguation)." I think the "from smoking weed" part is not very encyclopedia like. Perhaps From smoking cannabis should be put in place.

– Is there any information as to _why_ plants produce resin? Is it a part of some repair mechanism? How does the high flammability factor in? Thx. Wikiak 23:28, 2 March 2007 (UTC)

> This article is about the chemical secretion and not the resin from smoking weed

Regardless, the resin from smoking Cannabis is a resin. It would not be out of place to mention it in the article.75.110.98.103 (talk) 15:59, 28 February 2016 (UTC)

Clarification of terminology

In England and its former colonies the word "Resin" is used to describe a synthetic substance while "Rosin", as defined by the Oxford dictionary, is used in reference to the natural substance produced by trees. In the USA and some other parts of the world the word "Resin" as defined by the Webster Dictionary is used to describe both substances.Geoffrey Wickham 02:14, 20 May 2007 (UTC)

Why do trees make resin?

Per THIS EDIT on the science ref desk, a major deficiency of this article is the lack of information on why trees secrete resin in the first place. Anchoress 01:13, 13 June 2007 (UTC)

Plural of "pharaoh"

The plural of "pharaoh" is "pharaohs", not "pharaoahs". Check it on wicktionary. And btw, it's not nice to use somebody else's user name to make a change. Ferred (talk) 07:59, 30 August 2008 (UTC)

Senso flooring

In what sense does the link to Senso Vloeren BV, Netherlands, a manufacturer of floor coverings, qualify for inclusion in the "References" section of this article? Wikipedia is not a linkfarm, and I can't see why the deletion was reverted. --Old Moonraker (talk) 12:53, 11 September 2008 (UTC)

Removed again. Thanks, User:Kaiwhakahaere. --Old Moonraker (talk) 05:25, 12 September 2008 (UTC)

Galipot

There is a link to a nonexistent article "gallipot resin". However, there is an entry Galipot. (It's possible to spell the word "galipot" with one "l" or with double "l".) As far as I know "galipot resin" and "galipot" is the same termin. Am I worng? Vbond (talk) 13:15, 16 March 2009 (UTC)

All the dictionaries I consulted said that the resin has one "l" and gallipot with double "l" is a clay pot. So I changed the article accordingly. Thanks for noticing this. Kingdon (talk) 12:59, 17 March 2009 (UTC)

Resin extraction

I just redirected "Pecherei" to "Resin extraction" with a {{R with possibilities}} template. Is "pecherei" a German word?? -- OlEnglish ^(Talk) 03:29, 21 April 2009 (UTC)

Ambered perfume

"In perfumery such products are often termed "ambered", based on fossilized resins being the source of the gemstone amber." Not really true -- "ambered" means that the perfume contains ambergris or its manufactured equivalent as a fixative. Amber resin is also used in perfume as a fixative, but it has different characteristics (toasted or burned, as opposed to ambergris's musky or animal scents). 67.100.92.82 (talk) 20:30, 22 December 2010 (UTC)

This appears to confirm that. I have taken out the doubtful part. Feel free to make such useful contributions directly in the article, if you like. __ Just plain Bill (talk) 21:44, 22 December 2010 (UTC)

As the verb it's the first meaning carried by the OED. Good catch! --Old Moonraker (talk) 21:49, 22 December 2010 (UTC)

Where grey amber (amber-gris, a sea-weathered, whale intestinal byproduct) is not available (largely due to it now being banned in many places), "amber" in perfumery and incense is usually a mix of benzoin, labdanum, and vanilla, in an attempt to duplicate the scent of aged grey amber. Other ingredients can and are often added, formulations vary widely, but those are often the three base ingredients. As noted, yellow amber (amber-jaune, the sub-fossil resin) can [rarely] be used in perfumery or incense, but it has a different smell to it. In perfumery and incense, "amber" usually always refers to either grey amber (ambergris), or the mixture intended to duplicate it. — al-Shimoni (talk) 02:30, 18 October 2015 (UTC)

Merge Synthetic resin into this article

A resin is defined as basically a gooey material that can often be converted to a high polymer. According to IUPAC. The distinction between synthetic and other resins should, IMHO, be presented in one article. Synthetic resins are more abundant in our everyday world than are natural resins, so we want to include the important content in the main article. But Its not a huge deal for me, I am just thinking about likely readers. We also have these two articles on natural exudates: sap and rosin. --Smokefoot (talk) 01:43, 3 August 2015 (UTC)

I vote NO. If you want synthetic resins to be the primary direct, just do it. Despite IUPAC's attempt to change the language to encompass only a modern meaning of a word, resin is a much older word and of course long predates IUPAC. The situation is much as with the word "pilot" which before airplanes pilot (aeronautics) meant a maritime pilot and has not been entirely subsumed, which is why we still have two articles. A similar basic reasoning (besides historical meaning-shift) to keep the plant resin article different from the synthetic resin article, is that plant resins are defined by origin not function or chemistry: thus, they don't always polymerize to a high polymer amber, in analogy to synthetics which derive their name from this type of process. Thus, some resins never polymerize to hardness and stay soft (the balsamic or gum resins). Others harden somewhat from loss of solvent (evaporation). This is the origin of rosin (which indeed has its own article), which comes from resin, but is not a high polymer and is not amber.

So some natural resins set like synthetic resins, and other commercially important ones do not. They deserve their own space to do it in.

Again, if you want "resin" to primarily direct to the synthetic resin article instead of the natural one, much as "computer" now directs to the device, not human computer, you can do just do that, and add an appropriate "other use" tag. But keep human computer. The job description used to be the only meaning of the word "computer", and a human computer is quite a different thing. SBHarris 04:42, 3 August 2015 (UTC)

See comments below. I agree that IUPAC is not godlike, but the idea that a resin is plant-derived risks being narrow and archaic. --Smokefoot (talk) 11:56, 3 August 2015 (UTC)

Oppose. The word resin in "synthetic resin" has been hijacked from its original use and applied indiscriminately to almost any fluid that can be polymerised to form a hard material. There is generally no other common ground between the two classes of materials, so I vote no. Even to imply they are the same kind of thing dumbs the topics down and promotes misinformation. I vote oppose because I think we should, as a matter of policy, resist the tendency towards homogenisation of topics. Diversity of topics is one of the characteristics of WP that makes the project exciting. In a paper publication this might become desirable simply to reduce cost, but a Wiki encyclopedia is designed to link up disparate topics. Plantsurfer 09:43, 3 August 2015 (UTC)

Well those are strong votes from experienced editors, so I will remove the merge. My feeling was that "resin" was hijacked by hippies to discuss the world of plant resins, leaving the more important area as a subsidiary topic. Synthetic resins do not necessarily polymerize, just like terpenes. It was not my intention to dumb down the article but to smarten it up by informing readers that it is a big world out there, allowing the to be shunted to "plant resins" and many other kinds of specialized resins. But in any case, thanks for the advice. --Smokefoot (talk) 11:56, 3 August 2015 (UTC)

I also found a volume from my favorite source on applied chemistry - Ullmann's Encyclopedia has a huge chapter on Natural Resins, which it also distinguishes from the synthetic types. Glancing at it, rosins are a type of resin and in fact are the really popular type in terms of economics. Otherwise for future reference here are the sub-groups of plant resins: acaroid resin, amber, asphaltite, balsams, benzoin, lacquer, copal, damar, dragon’s blood, elemi, frankincense, galbanum, labdanum, mastic, myrrh, sandarac, shellac, styrax, Utah resin, Venice turpentine. --Smokefoot (talk) 12:52, 3 August 2015 (UTC)

That's useful. Asphaltite is a petroleum bitumen, not a product secreted by plants, though it may be ultimately derived from plants. Shellac and lacquer are of insect, not plant, origin. Most of those you list have their own articles and should be linked up to this one: amber, balsam, benzoin resin, copal, dammar gum, Dragon's blood, Elemi, frankincense, galbanum, labdanum, mastic (plant resin), myrrh, sandarac, styrax#uses of resin (refers to Benzoin resin, turpentine. Add to these Canada balsam, Balm of Gilead (though that barely mentions the resin), Boswellia, gum guaicum (surely a spelling error in this title?), Hymenaea courbaril, Spinifex resin, etc. . . We also have articles onPetroleum resin, Pitch (resin) and individual articles for most of the named synthetic resins, for which Synthetic resin should be acting as a hub. My point is mainly that the diversity to be covered in each of these main articles is huge, and there is much more work to be done on them to link up the many separate topics. Plantsurfer 13:45, 3 August 2015 (UTC)

I don't think a merge is appropriate, but maybe resin (disambiguation) should be move to the base title. Looking at the incoming links, I see many that from their title likely should be going to synthetic resin. Plantdrew (talk) 20:54, 4 August 2015 (UTC)

The Opening Definition

The opening definition says:

> In polymer chemistry and materials science, resin is a "solid or highly viscous substance, usually containing prepolymers with reactive groups."

The terms "prepolymers" and "reactive groups" are not defined, and are therefore chemistry-jargon. Therefore, from the start, the article suggests that the rest of the article will be unfathomable to the average reader. "Jargon" serves to turn people away.

Perhaps the opening definition needs an overhaul into something more general, recognizable, understandable. You can get back to the prepolymers and reactive groups later on in the article.75.110.98.103 (talk) 15:59, 28 February 2016 (UTC)
