Hi I am looking to do an extraction on 5kg of root bark and the "cake method" seems to make most sense. I know what I am doing roughly but could use some advise, firstly would 10 litres of Ipa and 1kg of lye be enough solvent for this extraction, secondly is there danger of poisonous gas coming off this mix? Any other advise from anybody who knows about this method would be greatly appreciated.

Thanks

um... 5kg?! What are you going to do with 50 grams of DMT?!

If you have never done an extraction before, i suggest starting with 100g to get an idea of what you are doing.

I could think of some things! 5 years worth of journeying for you and everyone you know?

Yup! That’s probably a more sensible way to start on this mission!

I have done extractions before and I know what I am doing. I am planning on turning the precipitate into a fumaric salt then freezing it for long term storage. I am more doing this for the sake of doing it as an experiment but could use advise. The method sounds and looks too good to be true. Surely I would have to acidify the solution in order to utilise alcohol's polar qualities rather then basifying the alcohol, that doesn't turn it into a non polar solvent does it? Help would be appreciated after I am done I will take pictures to help others.

I would try this method out on 500g max at first to get a feel for it, it hasn’t been played with too heavily. There doesn’t seem to be any other reports of use except that of the tek’s creator.

I too am quite interested in working with this tek as I would like, at some point, to do a very big batch and not touch extractions for a few years. I will be waiting until there are a few more people who have used it successfully first though.

it's an easy extraction less the filtration which i recomend doing with a large sheer cloth....will take many days to make the cake....hard to disolve...use hot h20 and break it up first.....need aprox 2.5 L per kilo and 25 grs of naoh

Am I the only one who consistently has fires happen when using this method? I turn my burner on low but still...

well, i hope you and your house/shop are all intact.

did you by chance read the *MANY* warnings of attempting this tek on a stovetop by myself and others?? safety has to be number one, personal safety!

i really like the idea behind this tek, and with the correct lab ware, properly set up and operated, will produce great results, im sure.

this means operating under vacuum, and recycling and recovering the solvent. evapping that much methanol in a room with yourself can lead to unconsciousness/coma/death, and if u leave it unattended, fire, or explosion of fireball can easily happen as well.

In my opinion, this tek is just too dangerous to not be done in sealed, pressure rated labware with relief valve piped outside. also all solvent should be recovered. if you dont have the right gear, please try a safer tek.

It amazes me that the way you perform the tek you make fires (read: this is hazard already), yet you keep on doing that!

What are you waiting for? For your flat (and your neighbours' flats and your neighbour's neighbours' flats) to burn down till you realise it's not such a great idea?

You fail epically in my eyes.

Ok so I fail epically. I guess I will have to invest in some more lab glass. But the way I've been doing it has worked ok, except for the fires here and there. They are easy to put out so they don't worry me much. I mean I just put the lid back on and they are out. But yeah I should stop doing that, you're right.

Anyway so now my question is, why is it that I am getting about 700mg of spice per pull (on my 4th pull now), rather than getting all 20g at once (from 2kg bark), as this tek declares is possible?

ok swim was doing q21 funfest drytek with caoh2 rootbark dried to powder,so it needs more naphtha to extract couse the powder absorb many of it.. swim used 1000ml for 200g of bark and about 400 of caoh2..his solvent is esane+7% of dichloroetane ,,afetr put the solvent in freezer overnight he yelded a very bit spice,so he though due to the dichloropropane his solvent had some problem to precipitate snow globes,so he put the jar in hot water,boiling water after pulling it some seconds into before let it in it but unfortunatly it broken anyway and the mix of solvent and powder mixed with water giving a sludge wheresolvent couldn't separate from the sludge...so swim is thinking to add a lot of lye to dissolve the bark powder and maybe caoh2 will separate in the bottom and he could separatre it and obtain a similar stuff of a/b,what do you think? anyway due to the fact that the powder contained freebase he has high suspect that it brings the freebase in it,and if bark will dissolve with lye,caoh2 won't,so he suspect it could brings some spice adsorbed in it,any advice? alwais when swim extract he has some problems,seems like a spice curse to him,last extraction he burned his hands and a lot of spice

Only SO MUCH dmt can dissolve/be held in naptha (or whatever solvent you have). Each solvent has a different "carrying capacity" so to speak. Just like you could put a shitload of sugar into a glass of water, definitely not all of it will get dissolved, only a fraction. Same thing goes for naphtha and dmt. If you're using only 300ml of naphtha per pull, then all you can expect is 700mg of spice per pull. If you want more, then heat your naphtha more (PLEASE BE CAUTIOUS, YOU ARE OBVIOUSLY FIRE-PRONE) and use more naptha. It's just basic chemistry.

ok swim did what he said..he pulled out some spice but he discovered a thing that was predictable..the dry bark-cacoh2 mixture that was washed with naphtha and than dropped in water has adsorbed lot of solvent,so when swim put his jag with the mixture of polar-nonpolar solvent he noticed that from the bottom of it,where the caoh2-bark has sinked some naphtha adsorbed by this mixture was boiling
obviously the naphtha that has boiled hasn't caried out anything of spice i guess,couse it's distilled from the sludge on the bottom so he thinks that the nonpolar solvent adsorbed by the sludge could protect it from free the base on the polar solution and maybe from the free solvent?

advices as always are very apreciated,theese things could happen to other people,a dry tek messed up XD hehe thanks

See you should really be using an electric hotplate for this, not a burner. Fumes are flammable too ya know!

oh no! it happens to swim too..

I am not gonna be mean or anything.. But you should really consider safety first.. I tried my first big operation once. 100g of mhrb a few times is a small task and easy operation. But then I got ballsy, and went for 2 kilos and after combining all my pulls in the end, my head was hurting so bad from all the vapor from the naptha and I had just poured my xylene in for the jungle spice pull. got to lightheaded and spilled every last drop of dmt filled naptha on the counter and floor. a total and utter careless waste.. All my fault, could have been prevented if I would have taken my time, set of fans and opened windows to expell vapor. I was to bent on just getting the stuff in the freezer. I forgot the most importan thing! SAFETY FIRST!!

What would someone need to set up to recycle the alcohol they evaporate? Lab glass/equipment?
