it is really cheap. can swim use it?

swim bought last time 25g of lime for ~3 pounds /ripoff?!/

As SWIM does not have a proper separatory funnel, this is a regular occurrence for him. He doesn't think it's a problem. That's the benefit of a nontoxic tek! SWIM suspects that a large amount of orange oil may result in some unexpected impurities that may impact the weight of the product.

Never heard of that brand but it is probably fine. Snoop around in some UK reef aquarium boards if you are concerned.

In general kalkwasser is totally safe to use. Reef aquarists are serious about kalkwasser purity because it is used as a constant supplement. Most people who use kalk drip a saturated solution into the tank constantly to replace evaporated water. A large aquarium system with intense lighting can evaporate 10% daily. This means any impurities present in the kalk will concentrate rapidly. Crappy kalk can contain traces of phosphate, edible lime is known to contain phosphate. This is bad for aquaria because it leads to algea overgrowth but it won't hurt an extraction.

search for deva botanicals (uk-based). they sell it much cheaper.

SWIM just did his extraction in the last few days. His yields were not as good as expected, only yielding around .5% or around 500mg from 100g of powder. He is going to test it this weekend for activity. SWIMs a little dissappointed because this is from the compras source, that according to these boards, others have had bad experience and low yields in the past. one even yielding only 4 trips out of 1800g's ! SWIM has ordered from the more reputable heavenly producers and hopes to get a bit more lucky this time around.

From the compras extract there definately was an emulsion between the vinegar and limonene, and even a heavier waxy layer that formed on the very bottom that was tan colored, has other experienced this? SWIM saved in in case it was active, because swim has yet to try the amber colored extract. SWIM thinks it was just something that was insoluble in limonene but still got through the filter from SWIM pushing a little too hard. Oh and it was only in the second and third pull, not the first at all.

the cacti iv been using so far came from compras i havent tried others yet.. however iv gotten .8-1.3% from the 4 extractions iv done

Thanks for the Kalkwasser info guys. Got 100 grams of peruvianus powder coming. We'll see how reputable this *bay seller is and will report. SWIM can't wait! Never tried mesc.

which bay vendor?

Could you use citric acid solution instead of vinegar with this tek to get mescaline citrate instead, and get crystals rather than the waxy acetate?

"Citric acid is a pain to use for mescaline extraction. It’s really hard to get rid of the excess citric acid at the end. SWIM tried all sorts of methods to get rid of the excess citric acid (freezer precipitation, acetone washes, etc.) and none of them worked well at all. Just forget about using citric acid. It’s better to use something that will evaporate away like hydrochloric acid or vinegar." - 69ron

I found this in 69ron's mesc hcl thread.

Thanks man

Well so much for that one I guess.

My friend is unfortunately having having a lot of trouble getting any of his limonene back out of the cactus mix. It all seemed to be absorbed into the gelatinous mass, maybe he used too much water, or too little. Only about 15 mls (!) limonene poured off with the french press. He tried to squish it out, but green ooze started coming through the wire mesh, and virtually no limonene came out. Anyway, he tried adding about another 150 mls of limonene, mixed it less vigorously this time. Seems to be holding its own against the ooze.
Has anyone else had similar problems? How much limonene should come out of the first pull anyway?

SWIM found 500g's on a well known auction site for £8. The seller does other chems like NaOH also.

Damn, my friend says the blob absorbed almost all that 150 mls extra limonene. Got maybe 20 mls back. He added yet another 100 mls...
I'm pretty sure he added too much water, the cactus mix was more like foamy salmon mousse than cookie dough.

Also his cactus powder contained a good portion of dust-sized particles, maybe 20% dust. I think maybe this could have affected his sorry outcome too.

I'm thinking maybe he should set the blob in a wire mesh sieve and perhaps the limonene will slowly filter out overnight.

He's floundering badly. Damn his guestimated measurements. Damn them.

What about using a french press ?

And I want to add that this thread got a drug geek friend of mine in peru all excited. He would like to follow the procedure and I hope we'll hear back from him soon because he promised me to tell me his experience.

He's using a french press. No dice.

Oh sorry, I've read too quickly. Im no chemist, but maybe it would be possible to dry the mess and start all over again ?

"TrancePlants".

i am also waiting for a package from them... ill let you know my yeilds

Does anyone know if "100% cold pressed & untreated orange oil" sounds safe enough to use?
