Hi, One could easily pull some nice clean spice from MHRB using the Marsofold tek found here: http://www.drugs-forum.c...um/showthread.php?t=6627 or with the tek I wrote found here: http://www.erowid.org/pl.../mimosa_chemistry1.shtml Just evaporate instead of freeze precip and substitute the heptane for naptha, it will work out better in your case anyway because it pulls a little cleaner and evaporates much faster.

You have patience ? Then do a slow crystal growing tek (Noman's tek followed by a slow recrystallisation)... No need for a freezer and it will gives you nice rewards

sort of related to extractions, wasnt sure where to ask. for those who know about pH readings, lend a hand? i bought an electronic pH meter and it came with a solution that was pH 6.8 when i tested it in the water, it read as pH 6.4 i thought, oh well, i can just -0.3 of every reading, but after a bit of research found the difference of 0.3 would be different to a higher pH and different again to a lower one. im thinking a difference of 0.3 is not going to make much of a difference in an extraction, as long as im around 2-3 for the boil and 13-14 for the base. but still, is there anyway i can know for sure what reading i am getting? is there any formula or something i could do? or is the reading always going to be slightly off? its from hong kong and the plastic damages so easily its almost impossible to callibrate.

To get a PH meter that is super accurate you would have to spend all kinds of money.Maybe your water is just slightly acidic for it not to read 7. did you try it with tap water or bottled spring water or distilled water?don't worry too much about the .3.when you acidify anything between 2 and 3 is good,and when you basify just pour in the base slowly while mixing till the solution gets all black and then add about ten% more to make sure you're up near 13.4.I used to use my PH meter,but the last couple of time I just go by the"let's watch it turn black and add a little more" technique and I'm yielding 1% from my rootbark.Is your PH meter "the Checker" the little red one?One thing that happens with those is that after a few uses they fuck-up and you will be adding your base and the PH will show rising till about 12 - 12 .7,then even if you continue to add NaOH all of a sudden you see it reading lower and no matter how much base you add it stays around 12.then you decide to check the PH of Potassium Hydroxide and you get a 14 reading.go figure

The buffer solution that came with the meter is used to calibrate it so there must be some screw somewhere on it to adjust it to the ph level of that solution. Hey Quantumbrujo! What tek do you use? Do you always do an A/B extraction or?

So do you use vinegar and no ph meter? What is the ph of the vinegar you use?

ok so swim tried nomans tek for the first time. this was his first ext tek so bear with him. basically 30g of mhrb was used as a trial run, being it was ordered from a supposedly bunk vendor. but he proceeded with the tek just for the sake of knowledge. everything went fairly smoothly, next time he should definitely use a seperatory funnel, but anyway onto the question. 3 naptha pulls were taken from the mhrb/naoh solution, and placed in one collection jar (mistake?) and was placed in the freezer overnight. this morning he couldnt tell if there were any snowglobes like noman mentioned. so the collection jar was placed back in the freezer to be dealt with later tonight. hes not expecting much of a yield obviously but should he still see the "snowglobes? he will probably recrystallize to make sure no lye is present. any help or recommendations will be greatly appreciated. will report tomorrow with the outcome.

Swim believes that how cold your freezer can get may be a big factor in that particular tek. swim is also questioning if he has bunk bark. less then a gram from 450 grams is either extraction error, freezer not cold enough, or bunk bark? Any more experienced monkeys out there have any suggestions?

you could also try evaporating your naptha down first, then freeze precipitate the crystals out. that will make your solvent solution have a higher concentration of spice, and you should get something from it

Anyone See a problem with Bestine and natpha being in same container? My friend wanted to compare the 2 for pulls but realized a small bit of naptha was still in aqeous while he added bestine to it.

so swim guesses it was probably the bunk bbb bark that gave him little to no yield, or possibly the amount of mhrb used.(30g) when swim removed it from the freezer and strained it through a filter, he could see that the naptha had a cloudiness towards the bottom. but after letting the filter completely dry nothing was there. so hes going to try again with mhrb from a different vendor. i wish him well.

As far as BBB and their shit goes, it would probably be a good idea to evap your extraction solvent by half before freeze precipitating anytime you're working with low yield bark.

thanks noman, swim will keep it in mind next time. but their wont be a next time with bbb thats for sure. he was thinking about trying to get some from an online auction site this time.

Hey Noman, the straight to base tek is excellent - although I do think something in regards to the excess amount of solvent used in it should be appended to everyone's directions; One could wager that many of the problems with freezer precip is because of low concentration in regards to excessive solvent in the numerous pulls. Also, a dry deep freezer instead of a standard air blower fridge type might help a lot as well. Seven, your trained monkey shouldn't act so quickly in judgment (not that SWIM has any experience with BBB) - cloudiness suggests alkaloids, and with such a small quantity of MHRB then it will be a small but definitely very noticeable amount (at least .15 gr). A guy I know has gone through a little trial and error with this, being a first timer in the process -- with a final net amount of .25 gr of slightly yellow spice with 30 gr of mhrb - and this is not with expensive inner bark. As an idea of the solvent quantity to get this to freeze precip correctly (after having a next to nothing freeze precip) - after adding a next day naptha pull to the remaining drained off solvent from the first pull, it was evaporated down from a few ounces to less than half a shot glass full of slight yellow tinted liquid that stunk noticeably of the spice- and that's when the magic occured after an 18 hour hold time. Even after all this, the guy said there was still a little cloudiness in the ice cold shot glass suggesting it could have been evapd even lower. Combine all the naptha pulls ,evap with fan down to 1/2 ounce or less liquid in a skinny shot glass if you have it (saran wrap top, secure outer rim with rubber band in case it falls over, let sit in freezer for at least 12 hours), then rubber band a part of a coffee filter over a wider mouth shot glass making sure to put a nice little pocket in it to avoid spill over and then directly from the freezer pour the liquid through your contraption - very quickly scrape any extra spice out with a utensil onto the filter paper and kind of chop and spread it out a bit, then gently pull that off the shot glass and set it in a safe place where it can ventilate on all sides & it will dry fast. One must do everything quick and with the filter technique because the spice will quickly re-dissolve back into naptha . Cover the remaining solvent and let your monkey do what it will with it (such as evaporating down even more, or adding additional late naptha pulls and repeating the process). Sorry if long winded, but this guy I know suggested that it was challenging to find this kind of detail in regards to this common problem with teks. Good luck..

Hiya folks, Ive run into some trouble with my teeny friend. He is trying to aquire some DMT (he's a spice elf) from acacia maideni and tested out a small batch. much to his annoyance, the final crystals are forming, however after 24hrs of continuous fanning with his little elf fan, the crystals are still (very fine crystals, was a quik evap process of only about 2 hrs he said) oily from the naptha (shellite). He said his fully sik and hecktik majic elf thermometer detects they are around 22 degrees C so they arent melted. some crystals are forming but they still have ALOT of drying to do... His main gripe to me was that these crystals are really nice and white... clear and no noticible colouration which is dissapointing because he has no idea how long they should take to dry and therefore no idea on when he can try them. there arent many of them (crystals that is), maybe enough for one trip through hyperspace that are spread over a large glass, special elf baking pan. can anyone pls let me know how long this should take to recrystalise or if at all why its not happening? im getting tired of his anxiety... much appreciate any help! (the tek he said he used was lex's tek) cheers guys!

I notice the latest version of Marsofold's tek includes a pre freezer evap and I'm pretty sure that wasn't the case when he first posted it at DMT World. I don't think the solution is decreasing the solvent though, you need a good bit swirling around in the solution to get to all the alks. Evaping by half or until it turns cloudy before freezing is one way to go, using heptane instead of naptha is another. Or one could just evap completely and clean the residue. With an eye toward dark spice extraction, I'm going to have the Antarctican do three toluene pulls, evap that and then separate the NN with heptane. He'll be doing a few experiments actually, and I'll be posting them in a thread on variations or amendmendments to the basic tek.

I recently have evaped down 1L of naptha to reveal 2 pils of white "stuff" that is pretty dry but when scraped up it turns to a yellowy brown goo... ive tried smoking a good size of the stuff (about the size of the fingernail on your pinky) and it melts pretty quick, bubbles for a bit then POOF lots and lots of white smoke, the melted turns black and the smoke is inhaled, it smells and tastes like plastic, but i have no effect given to me from it! the White stuff has formed a "cakeish" thin layer on the bottom of the baking dish... quite a bit oif it... its not sodium hydroxide i dont think cause NaOH doesnt melt? i think... i tried ot melt some and it didnt work... can anyone tell what the bloody hell ive extracted?

[quote:03338fe635]can anyone tell what the bloody hell ive extracted?[/quote:03338fe635] This definitivly look likes DMT. Chek the appropriate topics about smoking techniques. Don't forget that you can purify your extract thru recrystallisation process.

[quote:6641054511]Chek the appropriate topics about smoking techniques.[/quote:6641054511] Don't forget that you can purify your extract thru recrystallisation process. well im using a lightbulb shaped Vial i 'aquired' form organic chem lab, its pretty much the size of a lightbuld and hold about 50mL of fluid. I put the cap in and heat the DMT through the glass, its pretty thin glass. i wait till the bulb is pretty thik with smoke, you cant see through the bulb at ALL at this stage. I then take the cap out and gently suck out the plastic harsh very white smoke, when i cant take anymroe, i cap it again and hold my breath for while. I keep heating till its kind of full again, i cant seem to get it as full as the first time, and then i inhale again slowly and deeply, and then by the end of the 3rd time there is pretty much no smoke appearing in the bulb... im using quite a bit of stuff each time i try this (no scales), i just tried it like 10 mins ago and the most i can see is the woodgrain on my cork bord above my head is changing shades in time with my music... lol. but thats like nothing worth sayiong "wow cool" over. its very slight... do i need mroe stuff to put into the bulb? if what im putting in isnt enough to surpass threshold i have some piss weak DMT or something else. i want to post 2 pics of what it looked like precipitating... does anyone know of a good FREE website i can post a pic up to put a link in here? cheers
