awesome, thanks for your guidance.. how long should I keep it in the fridge? and the freezer? Also someone mentioned pulling some crystals out after a few hours and then leaving it to sit for the long run..any suggestions?

Next time you pull, you will NEED to be more careful to NOT get any brown gunk. Just think of it as poison! Plus a time waster if you have to re-x. Use an eye dropper for the last part of the pull. You want the eye dropper to be against the side of the glass and it will suck up the part of the naphtha liquid tension that curves up the sides. You will be able to see what you are picking up. If you get some brown gunk (mix with lye) then you just squirt it back from the eye dropper. If it gets in your tray, then you need to tip the tray to the side and the naphtha will slant and leaving the gunk stuck on the glass of the tray. Then you just use a tissue to wipe it up off the tray.

Good luck!

Show us the final product you get from this extraction! we wanna see some X-tals!

ELEC KOOL AID:

Noted. If I had just been a little more careful I could have avoided that, but live and learn as they say. The turkey baster I have actually was doing a fine job, next time I'll definitely try the eyedropper for the remaining thin layer of naptha.

Right now the re-x solution has been in the freezer for 12 + hours, I see crystals on the bottom.. wondering if it's time that I dump them / filter yet or leave em in longer?

Alright so getting a little antsy...

1) took some pics of the jar, you can see crystals on the bottom
2) I thought they were loose, turns out they are are a frozen mass
3) poured out contents of the jar into another wider container, taking the loose crystals with it
4) turned original jar with frozen crystal mass on the bottom upside down so naptha and crystals can separate

now what?

pics

let the jar sit upside down like that in the freezer for an hour or so some of the residual naphtha will leak out. then take it out of the freezer and set it right side up someplace for a day or so. you can use it once it doesn't smell like solvent any more. the stuff with the loose crystals can also be set out to evap, or you can retrieve them with a coffee filter. they will go back into solution if you don't put it back in the freezer however.

alrighty ALErT!! I uncovered the jar and placed a piece of paper towel under it to capture any residual naptha falling down.

In a few mins it will be placed out of the freezer ..and allowed to warm (with the cap on, barring condensation)

Fail

I scraped up the crystals from the bottom of the jar thinking to spread them out on a plate and have them dry, but they scraped up into goopy clumps and it looks like I have much much less than what I began with.

Ironically I had a better product to begin with, as the xtals were white and fluffy .. after this re-x they look yellow and gooopy.

cams dead ill take some pics if I can. Going to give it another try.

So you said it was goopy. Did you put it in the freezer or evap?
What you need to do is leave the solvent in there and place it in the freezer and let it precip out for like 12 hours covered. Then drain off solvent and then stick it in the freezer again for at least 2 hours with no solvent in it. It should have nice xtals. If at any time you leave the solvent out in the warmth, then it will turn to goo. You have to keep it cold at all times until the solvent has been drained and placed back in the freezer for 2 hours.
Oh and when you take it out of the freezer you need to cover it up so condensation wont form from the cold inside your container when cold reacts to warm air. Cover it for at least 20 minutes. Then you should have nice Xtals!
If you have your goopy stuff now, just add a bit more solvent and cover it and toss it in the freezer. And follow the directions I just mentioned.

Any other questions, please ask. Or research in the wiki / forum.

I freeze precip'd it. I think my mistake was not putting it back in the freezer (uncovered?) after taking it out and initially draining the naptha. That would explain my mysteriously disappearing crystals.

I also didnt notice that my radiator was on and the windowsill I had them drying on was heating up! Live and learn.

The good news is that bit of paste/goop turned out actually to be very usable DMT powder/crystals .. just had to let it dry and scrape it up! So I did recover a good amount. Don't throw anything away!

Everything I got was very yellowish/off white, however. No pure white DMT here. Will take some more pics and update. Have a final batch evaping now, and I will take your advice Kool-aid and re-dissolve my mangled crystals from the prior freeze precip into the naptha from this final pull I have left over, and precip them again all together, the right way. Thanks!!

Good job toxic! your getting it. one bit of advice for you, wide mouth low profile containers. They allow your product to dry and evap faster, they dont get knocked over as easy. Wide mouth mason jars work great.

Nice job.

Well here we go You can see the full spectrum of my attempts.. the biggest pile is my last batch. It is a beautiful , fluffy creamy color that glimmers and sparkles in the light.

The darkest orange batch is from heating the mixtures. I would not heat again IMO it is a PITA, besides maybe a warm bath in the sink but even that caused an overflow once or twice to this very stoned preparer ~_~

Freeze precip is def the way to go! Learned so much this time. Keeping all instruments/containers/workplace clean is vital. Not deviating from plan/tek. Writing the steps down is a must for clarity and checking where you went wrong! Never throwing your soup out!

My yield was pretty bad, I estimate around 7 grams for over a pound of MHRB, but what can I say, I have enough to last a good while and do plenty of exploring in hyperspace.

Thanks to all who helped!

Thank you for starting this thread, and thanks to all who contributed. It's helped me etch the extraction process into my brain. Happy travels=)

Great job!

thanks =] and I'm glad some found it of use!

EDIT: Some great advice in this thread.

One major tip (That I have to try & follow myself next time) and what I was confused about, + I suspect led to my low yields is ... evaporating the naptha down to a certain volume before freeze precip'ing. What is a 'certain' volume? That is still murky to me, but I think if your Naptha starts getting cloudy (showing signs of super-saturation) then it is good to go in the freezer..

My biggest yield was from my first pull ever, following the video, when the Naptha was simply evap'd away. You can see the size of the crystals left on the tray!

After that, I experimented with more pulls using more MHRB, and freeze preciping the naptha but it took much more to achieve the same amount.

BTW: Just got my GvG in the mail .. might be MiA for a few!
