I measured 100g of dry Peruvian Torch chips.
I then made a solution of 75% EtOH/H2O (Everclear brand) saturated with Aluminum Sulfate (alum), dissolved by rigorous shaking until no more would go into solution.
This alum saturated everclear was added to cactus chips, just enough to cover. An additional tablespoon (aprox) of dry alum was later added directly to the soggy chips.
This was left for about 18 hrs at room temp, by which time cactus had absorbed all of the liquid.
This was placed onto a food dehydrator sheet and dried at 125F (52C) for about 12 hrs.
The dried alum treated cactus took on a distinctly hard, brittle, rock texture and appearance (like a box of pebbles). This was ground with a coffee mill into powder.
I added 25-30grams of bentonite, a natural silicate clay ("aztec secret" brand), to the milled powder.
A solution of 3g agar powder (telephone brand) stirred into 1L (+/-) of cold H2O then brought to a boil until agar was dissolved and "bloomed." This was mixed by hand into the cactus/alum powder and poured into large ice cube trays. The total volume of the liquid at the point was less than 1.5L. These ice cube trays were placed in the freezer for 12 (+/-) hrs to allow agar to set and then freeze completely.
The green cactus cubes are put onto a dehyrdrator tray and dried at 125F for 12-18hrs, breaking up the drying cubes into smaller pieces every few hours. The cactus cubes went from ice, to jello, to spongy/slimy, leathery, then brittle and dry with the final consistency of similar to chunky cornflakes (but to be more accurate, if obscure, the stuff feels exactly like the textured soy protein isolate/TVP dried chunks sold in bulk sections of healthfood stores in North America.)
These crushed cactus/agar/alum chunks were powdered in the coffee mill. The milled powder was combined with 100g of CaOH (wages brand). This flour was covered with 50/50 EtOH/H2O to a mudpie consistency (like a pancake batter). As expected the alum and lime reacted at this point (fizzing, foaming like baking soda/vinegar, but milder/slower). The bowl went into the dehyrdator (150f) for 2-3hrs until it had a more cookie/biscuit dough texture and could be scooped into "cookie" sized portions and placed onto the dehydrator sheet and "baked" at 125-150f (forgot) for 2-3 hrs until dry and crumbly. This was crumbled into a powder and put back in the dehydrator till dry. This greyish powder had an aromatic/mediciny smell distinct from the plaster smell of lime. This was covered with approx 500-600ml of everclear and placed on a magnetic stirrer for 48hrs.
This was decanted, then poured through coffee filters to separate particulates. This filtered solution was placed into a pyrex dish, adding to this a probably excessive amount of glacial acetic acid (about 5-10ml?). This was evaporated to about 1/2-1/3 at which point insoluble compounds were visible as particulates. These were removed by paper coffee filters.
This lighter, transparent acetate liquid was put into the dehydrator at 125f for about 12hrs until the liquid is evaporated.
The acetate tar was scraped off the baking dish easily and collected for assay or further extraction.
My goal was to produce a cactus reduction/tar that was of comparable quality to those made via IPA soaking, but requiring less solvent than is called for with these alcohol isolates. My research lead me to early patents which utilize processes not often explicitly addressed in the cactus extractions found here. Of particular interest are the known processes treating the pectin-like polysaccharide cactus mucilage with metal salts (alum), adsorption of phytochemicals onto the surface certain minerals/compunds (acid bentonite, agar, and aluminum hydroxide from the alum/lime reaction) and their elution into selected solvents (acidic/basic everclear). Both processes—the selective capture and release of target compounds—are relatively accessible, both conceptually and materially, to laymen (like me); generally the process of desolubilizing pectin-like cactus slime with alum, adsorption of desired alkaloids onto seaweed and minerals and elution into alcohol seem safe, that is safe relative to established methods, and might be used to good effect as an adjunct to standard extractions, like the iso tar/resin routes for cactus medicine.
On the other hand, the quality of the product from this or any first "experiment" by a layman are VERY MUCH SUSPECT in terms of errors that could make such a process or its products ineffective, inferior, or even deadly. In this case, using methods and materials which are (as far as I can tell) untested for making cactus tar resulted in a light yellow, transparent liquid that looks about as weak as nun's piss next to the thick black/green ink that I have ALWAYS gotten before with tested and effective alcohol teks using vinegar. I don't have to weigh it to tell that the overall yield is much less material than I would expect from 100g of ANY cactus I've extracted—strange after all nothing was taken out of the cactus/alcohol system, instead I added a large volume of material to end up with less extract.

QUESTIONS TO THE EXPERTS IN ADVANCE OF BIOASSAY
First off, what the hell is in the tan/brown tar? What's probably not in it vs true ISO tar? It looks almost identical to cannabis wax, so I'm guessing that this is some wax/lipid fraction (as opposed to chlorophyll in typical alcohol extracts). ???
What dangerous reaction products might have formed out of alum, acetic acid, lime, agar, or aluminum silicate clay? Are these likely remaining in the tar and how might I remove them?
What are the chances that this extract will have a comparable effect even close to the darker more complete tar isolates?
Am I totally naive, misunderstanding some key concepts of the science involved here?? I'm not conceding total failure just yet, but I can't find it reassuring that no one within the long shared project of Trichocereus extraction, accomplished kitchen chemists included, would have attempted this route?
And if this hacktus tar is active enough to attempt on another batch—which for all my pessimism I really DO hope it is—what tweaks/improvements can be made? Can/should the dried tar product be dissolved in 99%IPA to eliminate more undesirable compounds? What part(s) of this elaborate, Rube Goldberg of a recipe, can/should be omitted or combined for a simpler route to the same results? Nix the agar? No need for bentonite? Are there any steps that seem glaringly counterproductive or redundant; does the whole procedure qualify for the dustbin of ideas?
Any feedback would be appreciated muchly.
