Hey y'all.
2 questions running through my mind. I searched the forums and other sites, but couldn't find anything specifically about this, so I figured I'd throw them out to the esteemed colleagues here on the Nexus and see if anyone bites.
1) Oxidizing during EVAP: I realize that everyone always talks about evapping and no one seems to think it any kind of problem, but I have also read that exposure to oxygen converts DMT into n-oxide which is yellow, gooey and non-crystalizing. It also seems that this is what comes out of most people's total evaps. I also realize that most naptha pulls need to be reduced and concentrated in order to freeze precip. Does anyone think that room temp evaporations with a fan can convert the freebase to n-oxide?
2) Naptha layer CLEAR or YELLOWISH: It appears from observing SWIM's pulls that heated naptha pulls can sometimes come up tinged very slightly yellowish. If allowed to sit and cool while still on the base solution, they will slowly lose some of this tinge. Allowed to sit for an extended time, they can go basically clear again. Is clear naptha better?
It seems that as far as question 2 goes, the tinge could either be spice or oils. Obviously if the tinge is a good thing and it goes away as it cools, than the ideal solution is to pull while yellowy and warm. If, on the other hand, the tinge is just random plant oils that the NPS absorbs when warm or when the polar solution is very high in such oils, than waiting for it to sink would result in cleaner spice.
note: the tinge spoken of is NOT emulsion.
