So I had great success with my first extraction, 100g root bark providing about a gram of clean white crystals with Noman's tek. Not sure on the exact yield because I started using the first crystals before my final pull was done but it was decent enough. I have the rest of a kilo left and I'm wondering what to do with it. What seems to be the best thing to do is just stick with what works, and do several 100g extractions until I'm out of bark. This should theoretically have the same result every time as long as I perform it the same way.

A larger (400-500+ grams bark) extraction is convenient and attractive though. The pictorials I've seen with larger amounts though tend to be very yellow and impure looking and would require rextalization for more pure product. I'm curious as to the yield differences in a larger extraction as well. So anyone with experience with both, is there any reason NOT to do a larger extraction? I will probably end up doing it anyway, and if yield/purity suffers I'll finish off the kilo with 100g extractions, but a heads up would be nice.

Congrats bro! SWIM just started too and it almost seems like extracting will be more fun than ingestions.... ANyways, looking at Noman's tek, it looks like it accommodates larger amounts than 100 grams, up to and including 1 kg... You just adjust the amount of base, solvent, etc., as needed. Did you give your bark the zinc treatment beforehand? Have you heard about this?

100g extracts all the way, cleaner, easier, less fussy. i'd say doing 5 small extracts would be easier than 1 500g extraction.

I like larger extractions as I find working with larger volumes a hell of a lot less fiddly. I don’t care about losing a bit on a bigger extract either.

With larger amounts I find it’s far easier to go for A/B over STB because you can reduce your acid solution quite drastically and can avoid working with massive volumes of basic solution. 6L acidified water used to pull 500g mimosa can easily be reduced to around 500mL and will also not need to be brought up to as a high a pH as in STB.

Regarding yield with STB I have found no difference between yields from 200g and 500g. I have only had a couple of goes with A/B so can’t give you the best answer, but I can’t see any reason for a difference in yield.

Swim likes the precision of 100g extractions. Heptane FTW!!!! Swim bought a box of mason jars at walmart for 8 bucks. That's 12 1 quart jars. Swim will usually do 6 extractions at once.

SWIM really likes the 1lb A/B extraction herself. So much faster to any comparable STB and just as easy. She can't wait to try out the BLAB as soon as the time comes.

Ahhhh, a kindred spirit My thoughts exactly.


BLAB is awesome, especially if you salt out with vinegar and do the heat conversion to fb; that gives you the option to make solventless changa as well as jimjam.

A gallon milk jug works well for a 200 gram stb extraction, just add enough extra water to bring the water level closer to the top so the naptha is easier to get out.

Swim's spice is yellow, but that's at least partially because he re-uses naptha so it's already partially saturated. Yellow doesn't seem to be any problem though .

Faster than STB? I find that hard to believe. I'll have jars in the freezer starting to precipitate about 2 hours after I start.

Of what weight though? After 4 hours of an 1lb A/B, the jars are in the freezer and it's pulled dry by the next afternoon.

I haven't. What's the zinc treatment?

I ended up doing this. Maybe I'll go even bigger next time, but this is a small step up and may actually be easier to work with the increasing volumes. I will report back tomorrow

First pull is drying, looks to be about a gram. Much yellower this time although still fairly white. I think this may have to do with using more naphtha? I might do less naphtha on the next pulls, using the same amount I used for 100g. I must say though, having pipettes this time was amazing. Never using a turkey baster again.
