SWIM is planning on following q21q21's tek, SWIM has 1KG MHRB. Would it be better to do it all at once or separate it into smaller batches? This would be SWIM's first extraction, but there doesn't seem that many places to go wrong with that tek.

If you plan on doing Q21Q21's tek, 1kg all at once would be nearly impossible. 100-150g is a good starting amount for dry teks.

Thanks for the response, do you mind explaining why? What would be the maximum?

i know not the tek in ref, but large extractions by thier nature may lose some efficiency vs small ones. they also take a fraction of the time, you decide.
large wet teks always seem to work fine

Now technically if you had a large enough container then 1kg is possible. A 5-10 liter HDPE2 bucket would be sufficient to make sure there is no splashing.

But really who needs over 10 grams of DMT????
A 200g batch yielded 2.355g of jimjam DMT for SWIM's roomie
That over 70 breakthrough doses!


As for the ease of the tek, SWIM's roomie did tek 1 (w/ xylene) though tek 2 is about the same difficulty.
He had seen SWIM do a couple extraction before, but SWIM made him follow the tek istead of relying on SWIM's help.
When he needed help with a step he edited his tek to explain the step better.
During the process SWIM said "It's kinda like making a smelly cake" to which his roomie replied "No, it's easier!"

So technically there isn't a lot that can go wrong, once the lime is added and it isn't too liquidy then it is pretty much idiot-proof (not implying anything)
Nonetheless it is ALWAYS best to start small scale on the first run.
Literally SWIY could try 30-50g just to get used to the process, then up it too a higher number when you get it right.

Thanks q21q21!

SWIM attempted just this. 1kg MHRB, with this tek. Scaling up volumes of materials (vinegar, solvent, water to salt out solvent, lime...)
SWIM is sure he used more than enough lime, and otherwise followed everything correctly.
(the vinegar acid step was indeed done prior to adding lime, using 100ml vinegar, 100ml water per 100g bark, adjusting to get to described consistency)
~ 2L xylene was used, and during salting out, an equivalent quantity of water was added in steps after the vinegar agitation.
Water was evaporated (took a while, below 100C), and revealed not much other that a brownish tar that is quite dry and does not appear to vaporize too effectively. There wasn't too much of this either.
SWIM added more Lime to the bark to be sure, then did another mix and pull with the same xylene. At this point the solvent was showing a yellow hue, once again clouded up upon vinegar agitation, hot water was added. There did not appear to be much yellowing of the vinegar layer though.
Evaporating this pull now.

Is it possible swim used too much solvent? (though the tek says what was used is fine...)

The bark was from the same supplier that swim previously extracted a good 3.8 gm from 1 lb, using marsofold tek, so swim know the bark is decent quality.

Any thoughts?

*Looking back on the tek, it mentions adding the water to salt out the xylene a little bit at at time:
"-Next add some warm or hot tap water to the solvent(it sinks to the bottom) a little bit at a time and agitate it.
SWIM's initial tests suggest that about 1ml of hot water per 3ml of solvent will dissolve 80% or more of the DMT while the it will take an additional 2-4ml per 3ml solvent to get the rest of the DMT."

Is this implying that small amounts of water be added, then removed before adding more? The picture shown of the salting process shows only a very small bottom layer.
Is this where swim went wrong, by adding all the water (albeit slowly) then drawing it out all at once?

From personal experience I find it much easier to work in small batches. I attempted a 1kg extraction once and it was a mess. Like q21q21 said above me, who really needs 10g of DMT sitting around? From a legal perspective it is probably much safer to work in small batches as well.
