yaeh its technically right but you dont want to leave all the crap in there as well. You want to crash just the crystals out and leave impurities in the shellite. When it goes cloudy it is good to go in the freezer. SWIM's didnt even go cloudy (it was still clear) before the freezer and heaps crashed out. SWIM evaped from 100ml to 20ml and all was good.

i read before that swiy defatted. when swim just did his first defat then with about 1/5 volume of acidified water to solvent, he turned his jar around slowly and it bubbles up like crazy. now he has like a million emulsions stuck in his solvent layer. is there anyway to get rid of this fast so he doesnt have to let it sit for a few days. it bubble up so easily it'll take hime like a week to do 3 defats.

A couple of things you can try: Separate the emulsion and run it repeatedly through a fine sieve. Add a cup (or so) of salt to the solution. (how much solution is there anyway?) Separate the emulsion and add a lot more solvent to it - like 4X as much as used. Push this through a sieve. As far as keeping this from happening, just be very careful about your agitation. Even that may not work though. While still under the delusion of Mistress Tantra, my friend produced emulsions with underbasified MHRB that one could slice like cheese. Marsofold wrote once of modifying his tek for psychotria - he did his normal procedure with no defat step and evaporated his solvent. He then redissolved the goo in acidified water, defatted - this time with much of the plant matter gone, basified, extracted and freeze preciped.

There's apporx 2 litres of solution. A warm water bath settled it down, and SWIM just finished his third defat, now time to basify. There's still a tiny, tiny layer, but SWIMs not going to worry about it.

after basifying the solution almost doubled. he then divided the soultion into two 2.25 litre bottles, with approx 2litres in each bottle. he then did a pull on each bottle with 250mL of shellite, so 500mL all up for 4 litres. this 500mL was left in a baking pan overnight, he then added 250mL to each bottle again and left the shellite in their overnight. in the morning the baking tray had not evaporated much, so he put a fan onto it. in the time he pulled the second solvent out of the bottles the shellite in the pan had gone very milky which put a big grin across his face. he then added the second pull of 500mL and it his sitting outside infront of a fan right this moment, the solution is still very milky and white crystals/powder is starting to come out on the sides. after it had been infront of the fan for a while, there's not much solvent left, just a thin layer. swim sent me this picture saying he is hoping this milky colour is a good sign?

That looks very good to me mate. You can freeze precip or even just evap it all from here and let it dry and see how clean it looks and then do a recrystalization if needed.

Nice work man.

alright. swim evapped it all down, and when he scraped it up he just got a goo all over his razor blade. so he put any goo on the razor blade, back into the pan and pured in apporx 100mL of warm shellite. he mixed it all around, left it infront of the fan for 10 mins, came back and it was very cloudy again. he mixed around again, then transferred into this jar which is going into the freezer now. [img:3ffa7b693b]http://img95.imageshack.us/img95/8365/milkyfq8.th.jpg[/img:3ffa7b693b] theres apporx 50-100mL in the jar, everything looks good? EDIT: 6 hours in the freezer and he can see the first sign of crystals forming around the edges of the glass jar. there was a pool of water at the bottom of th jar which has now turned to ice, is this going to cause a problem, does he need to get it out of there or can he just pull it out when he filters out the crystals?

Not 100% sure on this one mate but I would evap the whole lot again till its totally dry and then dissolve in shellite and freeze precip again making sure you have it tightly covered in freezer to prevent moisture getting in. A shotglass and 2 layers of glad wrap with elastic band work well. It is easy to scrape crystals out of shotglass as well cause of the rounded bottom. Maybe someone else has a better way of removing the water though?

Ok Great , please don't tell SWIM he fucked his whole extraction. SWIM got home this afternoon, opened his freezer to se loads of white snowflakes floating around in his jar. Made him quite happy. The solvent was basically clear so he though, why not filter out now? He shook it up, poured it into the coffee filter, removed the water/ice and let it sit for 10 mins. When he came back, the filter was dry, there were no crystals in the filter paper, and the solvent was still clear. WHAT WENT WRONG? All that SWIM has learnt is to do the filtering IN the freezer next time, but does this really mean he has to do a WHOLE extraction all over, just because he made that silly mistake? What happened to the crystals? They are not in the solvent as it isn’t cloudy and there is nothing in the filter paper?

geez mate , try washing the filter in warm shellite to redissolve any dmt in the filter. Add it to your existing shellite and evap and freeze again. The dmt cant have gone anywhere so its just a matter of reclaiming it. I dont use a filter I just pour the shellite off and let the crystals on the side of the glass dry thoroughly before scraping them up. good luck. Anyone else had this problem or know the solution?

Alright, SWIM said he's got some warm solvent running through the filter paper right now. He will evap it all and re-dissolve the left overs. Pray to the gods it's still there. EDIT: Ran warm shellite through the filter paper twice. Solvent is still clear as water. Should I evap down until cloudy again before putting in freezer, or just put in as is? Pretty pissed off. My bet is most of SWIMS dmt is stuck in the filter. At least he learnt a lesson for next time.

I would just evap it all and see whats there. If while evaporating it goes cloudy put in the freezer. You never know. SWIM once had 20ml of clear shellite that he thought had nothing in it but once in the freezer for 3 days got .15g out of it. Not much but better than nothing.

SWIMs exact words: [quote:40c7c358e6]Haha, infront of the fan for less than 10 mintues and it goes cloudy. If you get 150mg out of a clear solvent, I wonder how much i'd get out of one which is cloudy. I'll let it all evap and see what happens.[/quote:40c7c358e6]

I would cover it and put it in the freezer now. I think the reason it goes cloudy in front of the fan is the rapid evaporation will be cooling down the shellite. Leave it in for a few days. It is worth the wait as the crystals take time to grow. Good to see you happy again.

Alright. I told SWIM how helpful you'd been, he told me to thank you. He said he'll leave it in the freezer for 3 full days. He basically did that extraction to make sure the bark was the right stuff, so now (once he's found a way to grind all the bark up) he's going to extract on what he's got left. [b:1fffacd072]USING 1KG OF BARK.[/b:1fffacd072] For the three 2 hours boils, how much water should he use in each boil if he was using 1 kg? Once he'd combined all the liquid into a container, how much should he have in their? He was guessing 1 litre for each boil, so by the end he'd have approx 3 litres or less? And assuming he had 3 litres in a bottle, how much NAoH would he want to 'pre-mix' to basify to 13. SWIM sends his thanks to anyone who can help out.

No worries mate, you are welcome. So many people helped me out here as well. Gotta pass it down the line. SWIM uses 3 parts vinegar one part water. enough to keep it covered while boiling. After all boils are combined it makes it easier to boil it down to a managable level so you can do your extract in one container. It is much easier to do defats and extractions in one container and you use less solvent. I have never done a kilo though so I dont know if there are any restrictions on how far you can boil down. Anyone help out on this one?

Why does SWIY want to boil bark in acid water ? Why not directly put the bark in lye and wait few days ? I thought it was clear today that the acid step was useless. Or di I missed an importnat info ? After few days in lye, SWIY's bark should become a thick mush, easy to mix.

First of all SWIMs bark is Acacia and very fatty, so I need the acid step to defat. Second, it is Acacia bark, the quicktek was designed for MHRB, what if there is some major difference in the barks and the quicktek doesn't work and I lose a kg of bark? And third, I don't know if tis is true, but I read letting it sit in lye for a few days means you get alot of extra lye in your final product. SWIM could always try the quicktek on a small amount of bark, but why? The A/B extraction works perfectly for him and he can do it all in a day anyway. If someone else has had any good experience with Acacia bark in the quicktek, I may consider it, but otherwise he'll stick to the traditional tek for the moment.

[quote:9603e3bb4b]need the acid step to defat. [/quote:9603e3bb4b] Is'nt freezing recrystallisation the best way to clean spice anyway ? [quote:9603e3bb4b]And third, I don't know if tis is true, but I read letting it sit in lye for a few days means you get alot of extra lye in your final product. [/quote:9603e3bb4b] This is just totally wrong. Strange urban legend coming from people who never verified by themselves. [quote:9603e3bb4b]SWIM could always try the quicktek on a small amount of bark, but why?[/quote:9603e3bb4b] Because 1) The lye will 'explode' all bark cells to a point that a weak acid will never reach. 2) the yield seems smaller with A/B than with Quicktek (which is logical). Assuming that the percent of usefull spice is lower than in MHRB, 10% more is not negligeable. http://www.dmt-nexus.me/...&highlight=#3287 [quote:9603e3bb4b]but otherwise he'll stick to the traditional tek for the moment.[/quote:9603e3bb4b] Maybe one day the Quicktek will become the 'traditional' However, Quicktek method might require more efforts because it is not that easy to separate the naphta from a heavy mush.
