I think this article needs an overhaul because there is not enough distinction made between coal tar and wood tar. I also disagree with the statement that wood tar is non-poisonous. It might well be contaminated with methanol which is very poisonous. Biscuittin 19:25, 29 May 2007 (UTC)

And i think something needs to be done about the 'tar spring' artical. Is it a tourist advertisement for iran? too much fluff —Preceding unsigned comment added by (talk) 21:01, 15 June 2009 (UTC)

"Dehloran Tar Spring" article needs to be moved to it's own page or removed in my opinion. Northroad (talk) 20:19, 23 July 2009 (UTC)


For the reason given above, I don't think it is appropriate to have tar in "Category:Food additives" so I intend to change it to "Category:Chemical mixtures". Biscuittin 08:43, 30 May 2007 (UTC)

And you should not mix Pine Tar with Tar. Thats just mean. Clearly you have never used Pine Tar or Tar, or you would never suggest such a preposterous suggestion.

Merge with Pine tar???=[edit]

I strongly disagree with the suggestion of merging "tar" with "pine tar". Suggest instead distinguishing between "mineral tar" and "pine tar" (or perhaps more generally "plant tar", although I am not familiar with any other plant tars beside pine tar). It is increasingly important to distinguish between renewable resources (e.g. pine tar) and non-renewable resources (e.g. mineral tar). They are not the same material.Ekotekk 17:37, 7 September 2007 (UTC)

I disagree on merger, the two have little more than a lexical relationship as they are chemically distinct. One is petroleum based, the other plant based. CApitol3 (talk)


Under uses it says "as an ingredient in cigarettes". That is NOT true. "Tar", as it's called in relation to cigarettes, is the resin left over from the smoke. It is NOT actually tar, it's simply a resin (though of course it's harmful). Apart from that, it is NOT an ingredient in cigarettes, but instead, a result from then chemical process of burning tobacco. That's almost like claiming fecal matter is an ingredient in food (you do the math). I'm not trying to defend cigarettes or "big tobacco", but let's at least tell some truth here... —Preceding unsigned comment added by (talk) 08:15, 22 August 2009 (UTC)

Boiling point of tar[edit]

People survive being tared and feathered. How hot does tar need to be before you can pour it on someone without injury? (talk) 20:14, 28 December 2009 (UTC)


What is Tar worth? —Preceding unsigned comment added by (talk) 15:50, 29 June 2010 (UTC)

What a nonsense[edit]

""A tar-like substance can be produced from corn stalks by heating in a microwave. This process is known as pyrolysis.""

I'd like to see more reference to sailing lore: sailors being called "Jack Tar", using tar to preserve rigging as well as spars and sails, and of course tarred pigtails. Fredily (talk) 07:49, 30 June 2009 (UTC)
