My first ever pull- how does it look?

[Sicho Naut]

My first ever pull from 80g MHRB using a STB tek at room temp (SpiritVeggie, which seems basically a more sophisticated Noman's tek).
Have yet to scrape and weigh-- Doesn't look like a huge pull but I believe I undermixed, so should get it with the next pulls.

I've read the sticky on spice colors, but the oily looking stuff in-between the crystals looks a bit weird. It's fully dry, no smell. (Solvent passed the evap test perfectly.)

What do you think? Thanks!

It looks very beautiful.
Nice grown xtals.
Also the color is very nice.

Regarding the fluid on the plate, I do not know as I like to grow my crystals instead of evapping completly.
Good job

Edit: It is important that you tested your solvent via evap.

I freeze precipitated, pour off solvent and then let it dry.
I did test my solvent via evap, left nothing behind.

Looks bloody beautiful.. the oily stuff is probably some form of DMT. It doubt it is plant oils .. I wouldn't expect such white crystals on top of oily contaminants. But I could be wrong. Either way.. you must be really happy with what you have there!

 

[Sicho Naut]

Someone told me the oily stuff is probably NMT, which supposedly tends to be more oily than DMT?

 

[acacian]

Being that you used MHRB I doubt it. Mimosa is basically exclusively DMT as far as alkaloids go.. especially when using naptha.. Any 'plant fats' would result in yellow crystals usually so I'd expect whatever is sitting below your crystals to maybe be another polymer of DMT that won't crystalize. Why don't you carefully take the crystals off the top and dissolve the non solids in a small amount of fresh solvent and try freezing/evapping again? Could always try bioassaying it too.. I bet its active. Seen this time and time again here and its usually mostly DMT.

Happily surprised at the total weight of the first pull: 0,76g, close to 1%.

Second pull looks different-- this was after my naphta turned dark orange/amber in color. I guess the re-x and water wash should purify it.

Third pull in the freezer at the moment.

Weight of the second pull: 0,506g

Lovely first pic. The second pull may be more orange simply because it has sat for longer with the base and more polymeric DMT has formed. The coloration is very intense, in that only a tiny amount of the coloured material will give a strong tint to a comparatively huge amount of product.

If it bothers you, a quick mini A/B should clear it up. Re-x of coloured material can be quite perplexing until one understands one is dealing with polymers, oligomers and polymorphs.

And you're already rockin' 1.5% yield - nice job!

Weight of the third pull: 0,466g.

Total: 1,732g, just shy of a 2% yield. I'd be happier were it not that I am a little suspicious of those second and third pulls. The third one was even more sticky/waxier than the second one.

If it bothers you, a quick mini A/B should clear it up.

Color as such does not bother me provided I am reasonably confident that the product is safe. From your post it would seem that you believe it is?
I was going to do a water wash and re-x in any case, just wondering now if the mini A/B is necessery for safety reasons.

More a matter of how confident you were that you didn't pull any base soup over by mistake. It seems from the first pull that you did so cleanly, and the progressive intensification of colour is consistent with the longer contact time increasing the proportion of highly-coloured polymeric material. Mini A/B would break down the polymer again to a greater or lesser extent, as well as removing any base contamination (assuming it doesn't get returned with the next round of base pulls, but tbh I think you got that covered).

The remaining thing is whether there's much trapped solvent in the oily material. Dissolving at least some of it in acid would allow you to estimate this, maybe more precisely than, say, by smelling it.

Indeed, quite confident that I didn't. I used a pipette with a thumbroller and watched that thing like a hawk; I also deposited the naphta in a vertical container (small beaker) first before transfering it to the freeze precipitation dish.
Thanks!

To clarify: I am quite sure that I didn't pull up any base solution, but according to the FAQ dark brown naphta (which it was from the second pull onward) may mean "microscopic suspended particles of the mimosa/black liquid which for some reason refuse to settle, but nobody yet knows for sure." This is the only reason why I feel some wariness.

 

[acacian]

It may mean that .. but if you were careful not to pull any base solution I don’t see why that would be the case.. actually it would more likely result in inconsistent scattered maroon speckles on some of your crystals. There’s a certain look to base mixture contamination and imo that’s not it..

If what is in that picture is a contaminant then you would have to have been pretty sloppy.. which I doubt based on what you’ve reported. You could try pouring some water over the dish.. if the water instantly takes on colour then you can reasonably assume it’s probably a polar impurity.. if not then I wouldn’t worry about it too much.

It is always good practice to let your solvent sit for at least 10-15 minutes to allow any minuscule droplets to separate.
