SOOO..... how does boiling/steeping the bark and reducing it instead of adding the lime directly to the vinegar-soaked bark make a tek that effortlessly yields greater than 1% of pure spice or 1.5% or more crimson jimjam goo into a frustrated non-working mess?

I was under the impression (having read through Amor Fati's non-toxic approach and other drytek procedures such as 69ron's mescaline extraction) that when using lime you need to follow drytek procedures. You essentially tried to use lime for a standard A/B extraction, thus it failed to work. 69ron has multiple comments on the drytek procedure and why lime needs to be used according to drytek guidelines in order to have a successfull extraction. If I remember correctly, in an aqueous solution, lime won't act as a strong enough base and your extraction will fail. I feel like this is a pretty fundamental principle of the dryteks upon which "your" tek is based.

One thing that was left out: the lime was not added so that it was a solution. It was added so it was a THICK PASTE. It really looked exactly like it does with the bark in it.

Right...adding lime wouldn't make a solution...you added lime to a solution...looking like it has the bark in it is not the same as having the bark in it. A thick paste made by adding lime to a small amount of liquid to get a paste-consistency is not the same as making a bark/lime paste.

It is hard to believe that this method wouldn't work. I do not think that the use of calcium hydroxide requires drytekking. SWIM once did A/B, basified with calcium hydroxide and pulled with xylene, no problem; the only problem was the big amount of insoluble and had to be let to settle away from the xylene before it could be withrdawn from the basic solution.

What I suspect to be the culprit is too little boiling and the absence of an acid (?) In an acid cook one wants to diffuse the alkaloids out of the bark and into the water. The diffusion either just happens with the alkaloids leaving the bark and/or there might be a certain amount of tissue damage that facilitates diffusion.

The presence of an acid (other than the ones present in the bark) esp an acid that would make a highly soluble dmt salt, aids diffusion. Extended boiling also aids diffusion and also causes a certain amount of tissue damage. Either factors appear to lack from the treatment of both batches.

Q21q21, did SWIY save the bark after the acid cooks? Maybe if he gives them the regular treatment (STB/Ca(OH) drytek/extended acid cook/etc) they may deliver the goods.

SWIM can say with a great deal of confidence and evidence that lime works as well as--maybe even better than--lye STB, if used in a specific way.

SWIM's first lime trial's % yield is rivaling that of his simultaneous lye extraction (which is saying quite a bit, considering his excellent results thus-far) with two pulls on each. SWIM finds that this certainly seems to work when the lime and bark are whipped up into a doughy paste (as with cactus extraction), which would probably generally require that powdered bark is used (though SWIM suspects that it's poor water absorbance would still hinder the process unless mixed incredibly well with a slight excess of water); however, SWIM's managed to accomplish this with whole MHRB using a blender. This is only SWIM's first trial, and the bark had been treated with heat and vinegar prior to the use of lime; though SWIM suspects this is unnecessary and will attempt to verify this in his third trial.

Most seem to have a hard time extracting with a lime solution, but that amount of water really isn't necessary anyway. SWIM can hardly think of an extraction that would require immersing the plant material in a solution, in light of recent developments.

Interesting how the use of lime and limonene are coming to center stage with two of the most important substances for the psychonaut (DMT and Mescaline). Maybe these should be referred to as "limteks"--generally referring to nontoxic teks that use lime paste and limonene.

Edit:
SWIM can somewhat understand why nontoxic drytek techniques haven't quite caught on with DMT, as he's attempted drytek with MHRB, acetone and sodium carbonate and botched it, and also with lime, sodium carbonate, limonene, and chaliponga and didn't get decent yields at all. He realized that the problem was that the mixture wasn't quite homogeneous (not a problem with cactus, considering how well it absorbs water), and that's the realization that inspired his latest experiments. SWIM also believes that drytek doesn't always seem to work because it's difficult to judge whether the material has been completely basified prior to drying, which will halt the reaction altogether, leaving it with incredibly variable results. So a properly homogeneous mixture that can remain moist should yield more consistent results.

shoot, another accidental omission. Vinegar was added in each steep and boil. So that's not the problem.

SWIM's not frustrated from the loss because he isn't anywhere near out of spice, he's just confused.
Bark is now the lime + concentrated brew paste is drying at the garage window, hopefully that'll work..
