Hello,

I really wish I was already in a position to test my theory myself, but unfortunately this may still take at least a few weeks... I have already "imagined" a protocol for a test but I am by far not yet able to perform it myself...

But maybe someone has already tested my theory or maybe someone has enough theoretical background to prove or disprove it...

I think that when pulling with a warm non-polar solvent of the light kind (e.g. naphtha) from a cold (room temperature) basic solution it would be more efficient to mix/let separate/decant the nps only once rather than mixing/let separate several times before decanting and simply doing more pulls (also less nps per pull?) would be more efficient/faster (if you freeze precip and save the solvent)...

The question is, if you mix/let separate several times before decanting and we call the amount being pulled 100%, what percentage would be pulled if mixing/separating only once before decanting? If this would be quite high, would that prove my theory?

Sorry for not giving a more elaborate explanation, but it's Monday

PS If anyone is interested in the test protocol I imagined I'll gladly post it
PPS I have also "imagined" a similar test protocol to check to what extent (if any) cells are still being lysed/ alkaloids being "freed" during the basic stage of an extraction...

I'm doing a test on pull lengths this week, I'm going on the same thinking as you, i normally do 5 pulls with 3 mixes per pull, but this week im gonna try a single mix per pull to see what happens.

Thanks and please keep us updated

I imagine that doing as much as ten pulls mixing/letting separate only once rather than three times you would still save a third of the time spent...

Solvent-wise I would go for equal amounts for comparative reasons, once the theory has been proven using less nps per pull might be interesting...

Cheers!

I certainly will

I have tried this and the upshot is:

Quick pulls = whiter precipitates
Long pulls = Yellower precipitates

Obviously the longer the warm naphtha mixes with the base mix, the more spice it will pull (upto saturation point) but naphtha, being naphtha, it will pick up other plant goodies including the yellow staining and NMT etc.

If you want clean white xtals then do quick (one shot) pulls BUT you will have to do a LOT of them to exhaust your bark of desirables.

If you don't mind, or actively want, the yellow product (and the full spectrum mix) then long drawn out pulls are preferable. (this ensures that you grab Everything that the bark has to offer which can be cleaned up later if desired)

Also see Understanding Polar Migration for an explanation on speed of transfer.

Also 1g of spice will sit comfortably in 30-50ml of warm naphtha...so pulling with any more than that is really overkill imo.
You just have to ensure that your vessel has a thin neck where the solvent is sitting and can be reached with ease, rather than spread out thin [wide mouthed vessel]

just a quick update

I did 5 pulls on a room temp mix with hot naphtha, I rolled each pull for 3 mins then allowed it to separate and pulled. I got slightly over 1% of white crystally magic.

I then heated the mix and pulled 3 times with hot naphtha, for each pull I shook the jar for about 10 secs and allowed it to separate, I did 3 shakes per pull. I got another 350mg of orange magic from these pulls.

so that's about 1.3% from the pulls so far. Im planning on starting a long pull tonight to make sure I got all the magic out

Hello 3rdl,

How much bark did you start with? MHRB or AC?
Amount of naphtha per pull?

Thanks

PLUR

about 100g of MHRB that was blended to a powdery slightly fibrous consistency,

3x freeze thaws in vinegar

cooked for 3x2 hrs in acidic water

based, salted and warmed for 2hrs

left to cool to room temp and pulled the next day.

each pull was with about 50ml of naphtha

50% evap before freeze precip.

freeze precip for 24hrs
