When presented with new evidence any scientist would evaluate said evidence and alter his views accordingly.
DMT polymorphism seems to be a logical explanation as to why pure DMT cam be yellow or have variable melting points.
I should also point out that lye is white so lack of color doesnt guarantee a pure product either.
I didn't mean to hit a sensitive nerve with you or anything, but according to the evidence that I have been presented with this seems to be the case. If you can provide evidence contrary to this I would be happy to go over it, and if the evidence points to DMT polymorphism being such wild speculation as you say, I'll gladly change my position on the topic.
-EG I'm not contesting polymorphism, I'm contesting that polymorphism has anything to do with yielding yellow crystals. I've seen synthetic DMT exist as yellow goo/crystals where NMT was the culprit. NMT affliction exists no matter where the entheogen came from. TiHKAL describes reacting NMT with acetic anhydride or benzoyl chloride to remove NMT. Column chromatography is an option as well. Sofar the only evidence I've seen regarding crystal coloration is that an excess of NMT/DMT-oxide results in the discoloration of the target product. You haven't struck a nerve bud  I see alot of people holding the polymorph responsible for yellow crystals. Yet the only article that can be cited uses the word "might". Playing devil's advocate there is no evidence at this time to authoratively state the polymorph has no effect over refraction of light within the crystaline structure. There is one thing I can offer as fact, and that is I can continuously obtain yellow urchin crystals, or transparent needlepoints. Each by following the same repeatable proceedure each and every single time. Thank you for your input, I get told the same things over and over like it's dogma, DMT polymorphism effecting Crystal color being one of them, anyone can say "your wrong" but when someone says "your wrong and here's why" it's another story. Thank you for providing a logical explanation for your views, I need to review all the evidence before I decide what is "true enough", but again thanks for providing a good counter-argument. -EG

Thank you for your input as well Orion, it's really helping make this clear for me, I'm a student and make mistakes, I think the best information comes from veteran extractors due to their experience with the compound and how it behaves, specially after multiple trials.
If you can recommend a good information source regarding this topic for me to review it would be much appreciated.

So as far as variable melting points, polymorphism is a good explanation, no?

No. I think there could be a polymorph. But here are two arguments I don't see prevented in these documents. 1: They have no idea where their DMT came from. It would be nice if they took an effort to describe the purity of their sample and how it was testes. Impurities will derail a mp test. And some of these melting points vary by a degree or two. 2: Partial pressure will also affect this, whether it drops the mp or raises it. Hence a pure sample is needed for this study, and nowhere am I seeing that they used a pure sample. In fact, the evidence suggests that their sample is indeed tainted as they're claiming isolation without knowing what they're isolating it from. Some impurities cannot be removed by a crystallation.

By the way I screwed up my wording there, I meant to say the piece says both solvents give the same two polymorphs but only the solvent they were crystallized in affected the colour, not the polymorphs themselves. It also makes no sense that they say one polymorph becomes the other and associate this with the colour change, even though they already had both forms from hexane and they were clear. A very self-contradicting piece of info. Art Van D'lay wrote:Smoalk. It. And. See.

A very self-contradicting piece of info. They also failed to mention the purity of both crystals. Could the hexane have retained more, whereas they precipitated out of the other solvent? With that data god only knows..

All good points, I'm going to carefully review all the information I can find.
Thank you for your responses,
