Thats confusing, didnt you do a whole procedure with xylene and water and they did NOT mix? :D Just because of this fact you were able to conduct your extraction, as both arent miscible. But nevertheless I would really not do it like this, there is no reason to further add water to help any evaporation of xylene regardless of miscibility. Just leave it in open air in a dark room, but I guess you already tried, otherwise you would not complain about the smell.

Again, washing Fumarates for some minutes with Acetone should remove all the xylene, no idea why it still smells like this as you say ...

Sorry that was a bit unclear -- dissolving the fumarates in water allows the particles to be very finely washed since the molecules will be all separated and the Xylene can finally be 'freed',so evapping off the water carries with it the Xylene (which should really float to the top and evap first). But I realize now a better, faster method of doing this would be to just dissolve the freebase in acetone and evap the acetone, accomplishing the same thing without any heating/oxidizing also...I am dealing with fumarates that will form a powder (sortof, they are very small clumps really which I think is the problem), and the freebase I end up with is a wax, so it's not so easy to just 'wash' this wax unless I dissolve it in something (I think acetone makes most sense).

Also - both the fumarates and the freebase taste hella gross like Xylene, and the freebase smoke is what is harsh, I'm not vaping any fumarates here..

The burning taste I mentioned would make my whole tongue and mouth numb for minutes on end. Not normal, and I am aware what regular spice tastes like. My only guess is that xylene must be stuck mixed with a lot of the plant oils in the product or something...the fumarate 'particles' don't dissolve in the acetone ever of course, so in theory they MUST forming clumps and trapping Xylene inside the crystal lattices as you said before, but in definitely noticeable amounts. Acetone wash didn't even improve the taste or smokeability at all when done on the fumarates

So the fumarates were thoroughly washed with acetone multiple times, and the fumarates did not smell of Xylene whatsoever upon freebasing. There must have been Xylene still in the fumarates 100% despite acetone wash, because dissolving the fumarates in water and evapping off the water again worked to clean the product, it no longer tastes strongly of xylene and smokes just fine. It for sure consistently removes a bunch of Xylene post-acetone wash...so confusing why a regular acetone wash hasn't been working for me.

Greetings Nexians,

I am not sure how to avoid a "Spaghetti" effect when asking a question on this thread but I have full trust the system is working.
I am doing my first dmt extraction: a BLAB with vinegar.
Is there a way to know when the limonene is exhausted after the vinegar pulls ? I did 3 pulls
but the pulled vinegar still have some faint yellowish color to it.

Cheers :want:

Normally thats quite right - dispersing something in a big amount of other solvent will also disperse any residual leftovers within the crystal network and then you can get rid of all the liquid altogether. But in this case as Xylene is not miscible with water, you will not really wet the Xylene and even though some may float to the top, a big portion will also just stick to the crystals because of adhesion forces.
It may be like dipping your hands in olive oil and then washing it with plain water - as oil has no wetability to water you will not get rid of the oil.

But the thing with Acetone works of course and glad that it resulted in a better product now.

First dont be fooled by the colour, even slightest amounts of dying agents may cause a coloration. To know whether it is depleted you could take a tiny amount of solvent, like 10 ml from 100 ml and then add FASA to it.

You will very likely see big clouds, the problem is that the clouding always seems strong, so this is not a way to directly distinguish if there is much material in or not. But then just wait for the clouds to form crystals and weigh this. If you just have like a few mg that you cannot even weigh, then in the residual 90 ml there will also be nearly nothing else. If you got like 50 mg or more, it may still be worthy to get that residual 450 mg from the other 90 ml Limonene.

I got some 30X caapi resin ( which is much easier to source here than vine ) and tried to extract the alk from it.
It was brewed in boiling water, filtered and then basified with sodium carbonate till a ph strip showed around 11.
Nothing seemed to have crashed out. I left it in the jar for few days and now there is a very thin layer of some stuff at the bottom of the jar.
Ph is still 11 so I am quite baffled why I dont see any serious precipitation.
If anyone can chime in it would be great :)
BTW, any point trying to raise the ph some more with lye ?

Thanks :thumb_up:

Hi guys
i have just finished the first part of my first extraction. i am doing a cold STB and i am using shredded MHRB, so i plan to leave the MHRB/water/lye mix sitting for about 3 days before i add solvent and go for my first pull.

my question is, should i be stirring it occasionally over those 3 days? or is it better to let it sit untouched?


thanks for the help <3

It's probably a good idea to stir the mixture as you have used shredded bark. Stirring will assist in breaking the bark down and releasing the magic. Had the bark been powdered this would be less important.

awesome thanks!

im glad to hear that, it means i get to do something rather than sit around waiting for 3 days :D

thanks for the help <3

Hey all, long time lurker, first time poster here.

I have a couple questions about Q21s JimJam tek: In the revisited article Q21 rewrote about his teks, he talks about one method of ingestion that consists of dropping a couple of tincture drops onto some leaves then letting it dry for several hours: would I have to first heat up the tincture to make sure no vinegar is present (if i understand correctly, vinegar's boiling point is 118 celsius, so letting it sit won't evap the vinegar.)

From this question comes the next one: If I heat up the tinctue to evap the vinegar, the end product seems to be of a gooey consistency: in order to infuse some leaves with this goo, could I place the leaves and goo in a shot glass with some ethanol and then let it evap and dry (á la enhanced leaf?)

Many many thanks in advance, your forum has proven to be a great place to learn about this substance, hope this is posted in the correct place.

i have tested 3 potential solvents over the last few days. newport, clipper and swan lighter fluids. i have seen newport and swan recommended lots of times, but neither of the three seem to have evaporated cleanly. the clipper actually came kind of close, leaving just a ring.

i am wondering if i am doing something wrong? i use the bottom of a glass casserole dish, which i clean with washing up liquid and hot water, then rinse well with water and wipe down with a micro-fibre cloth.

i cant really see the residue until i shine a torch from the other side, but i assume if ANYTHING is there then its not good enough.

i was supposed to have another solvent here today but i guess its delayed, hopefully i will have it in the next couple of days and hopefully that one works! this is driving me crazy!


any suggestions would be very appreciated.

thanks <3

edit:
would it help to put the un-evaporated remains in an oven at low temperature?
and am i just being overly paranoid about the clipper fluid? :D

edit 2:
i just found a comment on another thread saying it is not a huge problem if you are freeze precipitating, which i am doing. is this okay if the solvent leaves a very slight residue?

edit 3:
even further digging has shown that some people who have been doing extractions for a long time say they always have some amount of residue left behind.
i think with the freeze precipitation and this combined i might have no choice but to just try it out and see what happens :/

i am going to do one more test, taking extra care to clean the surface very carefully, then i am going to probably just choose the cleanest one. not sure if thats the right thing to do. at least its only me smoking it :D

thanks again guys, sorry for the constant edits <3

Deconstructing Changa: Sanity check

Swim has some changa she wants to convert back to raw ingredients.
Her plan is:
1) Soak in IPA to get the spice out.
2) Then acid cook to get the harmalas out.

Sounds OK to you ?
Thanks :thumb_up:
( And sorry Pedro for jumping the queue... but I believe the system will accommodate )

no problem. my question is weeks old and i dont need an answer any more anyway :)

i hope you get an answer, i would like to know how that works too.

As a footnote, in the lab where I once worked glassware used for detergent analysis was always thoroughly washed with HCl and stored separately. There's every likelihood that residues from the washing up liquid remain on the glass which get redistributed by the NPS and become more visible as a result.

thanks! <3
that was my concern with that. in the end i recreated my evap process, but with clean naphtha, including tilting etc. that left no marks.
it does make me question how well i am cleaning my glassware though, at least the precipitation dish and solvent storage jars. maybe i should invest in some HCI for those items at least.

Can I base ( with SC or lye ) a salt saturated acidic rue soup same as I would if there was no salt present ?
Thanks

Yes, although the common ion effect might cause some co-precipitation of salt, depending on the concentration of alkaline solution added. You can avoid this by using SC/lye solutions of a limited concentration, or of course by using ammonia.

As long as the sodium ion concentration of your SC/lye solution is no greater than that of a saturated salt solution, there's no chance of salt precipitation. In fact, you have a bit of leeway in the upper direction, because the concentration of chloride ion drops as the base solution is added.

The pH thing is somewhat different, over in the VDS protocol thread it became clear that pH can change seemingly erratically both because of rates of freebase harmaloid crystal formation and - especially when using SC - dissolved CO2.
