OK, I've been comparing the "feel" of batches of spice prepared by different teks.
For my money the effect of spice prepared using lower temperature for extraction eg using
a crockpot ala marsofold's tek is superior to spice prepared from an extract that has been
subjected to extensive boiling.

So I have been thinking about my next extraction.

I propose a "low temperature extraction" using the following steps:

1 initial extraction using the herbal percolator with acidified water pH 4 no hotter than, say 130 degrees, or whatever
minimum temperature is necessary for the percolation to actually pull spice, as governed by experience. Using ascorbic acid as the acidifying agent.

2 reduction of that extraction using a home food dehydrator. Some fussing might be necessary to adapt the available devices to the "dehydration" of a liquid, but I'm thinking it could be done. Dehydration temperature again no hotter than the extraction temperature. Dehydrate until the liquid is thick and syrupy, not necessarily all the way to a resin.

3 addition of CaOH to produce a crumbly consistency similar to Q21Q21's tek

4 extract using favorite solvent.

I am interested in experiencing the effect of spice prepared at the absolute minimum temperature that allows efficient extraction and reduction.

Before I proceed, any feedback or suggestions?

if you don't want to use heat, you can just do a dry tek.

Just do any tek at room temp...works fine...you'll just yield less.

I'd challenge you to test this blind, I'd think you couldn't tell appart the different results and that it's self suggestion.

Wouldn't lower temperatures yield less spice, making it more inefficient?

thanks for the feedback. All is appreciated.
OK so the difference is probably in my head, but I will probably try a low temp
extraction just for the hell of it. Comments about low yeilds are appreciated. So is the
suggestion of using a "dry" tek which I hadn't considered.

I dont mean to discourage you. In fact I actively want to promote experimentation... I'm just suggesting that , once your no-heat extraction is made, you do a blind test and see, after your extraction is done, if you can really tell the difference or not. It would be interesting to know

From my understanding, low temps don't necessarily mean less yield. As far as the hot water bath goes, once the solution has been basified and you are doing NP solvent pulls, not using heat would just mean less alkaloid per each solvent pull. Warm NP solvents just hold more DMT than room temp solvent. So the same amount of spice could easily be yielded, as long as the person performed more NP solvent pulls to make up for the lower solubility.

As far as the acid boils go, I have tried using fully boiling water and I have tried just simmering around 130 F, and I did not notice much of a difference in yield between the two.

Endlessness, thanks.
I have always liked your screen name.

the thought just occured to me now, that you could use freezing to lyse the cells instead of heat.
just moisten the bark and stick it in the freezer over night.

so now i am wondering to myself.. maybe there is a way to extract MHRB and preserve the yuremamine?

hopefully endlessness will come in here and dispel any whisperings of faith in my pipe dream

Yuremamine is unstable to bases, so how would you proceed to extract?

right on cue.

maybe use acetone or isopropyl (i am too illiterate in solubility to know what solvents would actually work) or whatever to pull the salted alks.. and somehow purify from there (maybe by cleaning it with a NPS to dissolve impurities after you get the initial extract?) or something?

clearly, i am no chemist
