White and yellow crystal formation with in the same stb naphtha pull?????

[Bluffblocker]

Why would there be some white and some yellow crystals in the same pull. I recently started pulling leaving my solvent outside to freeze under a fan over a few days to form larger crystals. Strangely enough I notice 2 different crystals forming but why? They both smoke as dmt would but hard to say much difference as this is a first to notice this

Nice photos. That's just what happens sometimes, having both colours. It looks like the yellow form grows more quickly once it has formed. It would be good if you compare the melting points of the yellow and the white forms, measured as accurately as possible. This should highlight them as the two main polymorphs of DMT.

Have you kept a record of the temperatures? And did you notice which formed first? I would strongly suspect that it switched over to yellow crystals once the naphtha had evaporated to a certain degree.

No I’m not sure how to figure the melting point of them. I just separated the two and kept them separated (didn’t even water wash the white like I normally do to reduce harshness)

A cpl explanations for this are that 1.Every solution will have swirls and eddys of solute where it is more concentrated when it comes to rest. In those areas there could be more or less dissolved fats, tannins, or other plant molecules. As the temp drops and precip starts, the ones with extra particles near them will color and the others will be whiter.
2. Multiple pulls mixed together in the pan. Some from a higher temp. so more oils came with it, will cause yellows. Or reused solvent...

This materialised on one extraction I did.

What you got here is most likely some goo that precipitates and accumulates in a spot after which xtals form and absorb some of that goo making them yellow. I've had the same thing on my last extraction and I did observe the goo precipitating first in the freezer. I think OP case is a prime case of DMT polymorphs.

IMPORTANT: spice color purity fallacy AKA is your dmt ok to smoke ?

I wanted to deal with an issue that commonly arises here. Often people ask 'is this spice ok to smoke', followed by some picture of some crystals or the description of the color of the spice. What I want to argue here is that spice color and how it looks is a very poor indicator of possible...

Looks like we're both using heptane?

I used ronsonol lighter fuel.

Here's a summary of what I did, I'm curious to know your steps maybe we did something the same resulting in goo (which is completely fine for me)

after the acid cooks I was letting the brew sit in the fridge and by the end there was a thick dark tar that settled at the bottom, I discarded it before basification but a little bit got through and I suspect it got pulled and formed the goo

I had this thought yesterday of a simple way to at least check if they have different melting temperatures. Placing the 2 types of xtals side by side on a thin dish and putting the dish on top of a bowl of freshly boiled water so that it would heat up with the water vapor. I think the dish will heat up relatively slowly and it might be possible to observe one type of xtal melting before the other.

To have reliable results ideally single shards should be used and placed flat on the dish to ensure similar heat transfer for both. If one type is more sticky or gooey than the other this might influence the heat transfer and give less reliable results. Multiple shards of each type can be placed and if all shards of one type melt before the other, then more solid conclusions can be made.

And if you have any simple means of measuring temperature it would be easier to measure the surface of the plate.

I think you'd only need a few mg and at the end you can wipe it off with some herb and enjoy the mild effects. So it might be worth trying.

I'm very curious about this so if you would like to attempt it we can think more about the details.
