Talk:Pitch (resin)

Untitled
I'm not that well versed in materials science, but could pitch be considered a dilitant material, similar to Silly_Putty? Both will shatter when impacted, but are ductile (I think thats the right term) when forces are applied over a longer period of time. Davepetr 20:15, 3 May 2006 (UTC)

Uses?
Nice little article, but could a little bit more be said about its uses? — Preceding unsigned comment added by KagakuKyouju (talk • contribs) 18:02, 8 August 2013 (UTC)

Genesis 6:14
This the pitch in the Book of Genesis 6:14 referring to the subject of this article? 05:45, 25 March 2007 (UTC)

This is the pitch referred to in Genesis 6. The Strong's definition for the word pitch in Genesis 6:14 is a covering or bitumen.

You can find more information on how it might have been done at Answers in Genesis http://www.answersingenesis.org/creation/v7/i1/noah.asp. Mind you, they do not cite sources and the authors have a very biased opinion.

heat-activated (softened)
I don't think the article explains this, but does pitch soften when heated ? If so, by how much? Can it be a flowing liquid at very high temperatures? Does it lose moisture, and become denser & even thicker? DaveDodgy (talk) 14:47, 13 January 2010 (UTC)
 * Yes, I was recently watching a documentary on the BBC about Roman influences on the British isle, before the Romans actually invaded the isle and there was a part about a shipwreck found in a British harbour. The shipwreck had been preserved by the load of pitch it was carrying. According to an interview with the people who uncovered the ship, the ship had caught fire and later got swallowed by the waves, the heat of the fire melted the load of pitch the ship was carrying. The melted layer of pitch preserved the ship for a long time. I'm not sure when or how the documentary was named I will look that up later, atleast this somewhat confirms that pitch softens.


 * There is a alot more, Romans used pitch as a weapon, an early thermal weapon according to this wiki Here. This website Here provides some information on a Roman vessel found in Britain. I hope this was somewhat helpful, I will return here should I find the name of the documentary.--Intouchwithbertj (talk) 11:22, 25 August 2010 (UTC)

where can it be bought
NO mention of where one is likely to find/buy pitch. I have NO IDEA what kind of shop would sell it. Please help, or update article, in a way that doesn't look out of place in the article.DaveDodgy (talk) 14:49, 13 January 2010 (UTC)
 * In the wiki pitch_(resin) there is a reference to pitch as bitumen, I'm sure that this material is available at bigger shops specialized in construction material. --Intouchwithbertj (talk) 11:28, 25 August 2010 (UTC)
 * You can't buy "pitch". The term is entirely archaic, and doesn't apply to any modern natural or manufactured substance. WCCasey (talk) 00:51, 11 April 2014 (UTC)

- @User:DaveDodgy

Pitch, also known as resin, can be found naturally occurring on/in pine trees, other coniferous trees, and some other types of trees around the world. Simply walk out into the woods and collect some. You can also buy pitch (resin) from various sources (try a Google search).

Archaic term?
User:LeadSongDog reverted my edit of the lead paragraph of this article, with the note "no evidence of archaic status". In support of my edit, note that the next paragraph says "Pitch was traditionally used...", and "Pitch was also used...". Those statements indicate "archaic status" to me. There's also the statement that pitch "is sometimes still used in the making of torches." Really? Is the making of torches something modern people do? (and where's the evidence for that statement?) Just for fun, try going to the store and asking for "pitch". Anyway, if someone likes it better the other way, I'm fine with that. Just for the record, my version of the paragraph follows:


 * "Pitch is an archaic name for any of a number of viscoelastic, semi-solid polymers. Pitch can be made from petroleum products or plants. A natural semi-solid form of asphalt (also called bitumen) was, in the past, sometimes referred to as pitch. Pitch produced from plants is also known as resin. Some products made from plant resin are also known as rosin. Other archaic names for natural asphalt include "tar" and "asphaltum"."

BTW - if sourcing is the only issue, cite tagging is more appropriate than reversion. WCCasey (talk) 00:36, 8 June 2014 (UTC)
 * Just because the material's use has decreased does not make the term archaic. Oxford is quite systematic about noting when a term is archaic, and does not do so for "pitch". Here is recent work indicating that coal tar pitch is still a large scale industrial product. LeadSongDog come howl!  04:01, 8 June 2014 (UTC)

In the given photo, why is there a Duracell 9V battery? Does it have anything to do with the experiment, or is it "product placement"? Fultie771 (talk) 15:49, 13 January 2018 (UTC)

I see that the same question was asked under the Talk page for the pitch drop experiment. (No answer given there yet.)Fultie771 (talk) 15:53, 13 January 2018 (UTC)
